Space-Saving Device Offers Low Max. RthJC of 0.36 °C/W and Wettable Flanks to Improve Thermal Performance and Solderability in Industrial Applications

To provide higher efficiency for industrial applications, Vishay Intertechnology, Inc. introduced a new 80 V TrenchFET Gen IV n-channel power MOSFET in the PowerPAK 8x8SW bond wireless (BWL) package with best-in-class on-resistance. Compared to competing devices in the same footprint, the Vishay Siliconix SiEH4800EW offers 15 % lower on-resistance while reducing RthJC by 18 %.

With on-resistance down to 0.88 mΩ typical at 10 V, the device released today minimizes power losses from conduction to increase efficiency while improving thermal performance with a low maximum RthJC of 0.36 °C/W. With its 8 mm by 8 mm footprint, the space-saving device occupies 50 % less PCB space than MOSFETs in the TO-263 package while offering an ultra-low profile of 1 mm.

The SiEH4800EW implements a fused lead to increase the source PAD solderable area to 3.35 mm², which is four times larger than a traditional PIN solder area. This decreases the current density between the MOSFET and PCB, reducing the risk of electro-migration risk and enabling a more robust design. In addition, the device’s wettable flanks enhance solderability while making it easier to visually inspect the reliability of solder joints.

The MOSFET is ideal for synchronous rectification and OR-ing functionality. Typical applications will include motor drive controls, power tools, welding equipment, plasma cutting machines, battery management systems, robotics, and 3D printers. In these applications, the device offers high-temperature operation to +175 °C, and its BWL design minimizes parasitic inductance while maximizing current capability.

RoHS-compliant and halogen-free, the MOSFET is 100 % Rg and UIS tested.

In an energetic discussion with Yatish Mohan, Managing Director, India at Rohde & Schwarz (R&S), a vision stood out: fusing leading-edge global technology with India’s strategic priorities in localisation, innovation, and infrastructure development. With India speeding up its digitalisation and security upgrades, R&S is positioning itself at the center — not only as a supplier, but as a long-term ecosystem ally.

Localisation & Compliance: A Non-Negotiable Priority

India’s policy climate is changing fast, and R&S is perfectly in sync with it. With a mandatory 20% local content norm for every government tender, including through GeM and direct procurement channels, the company has designed its operational and supply chain models accordingly.

Their SKD (Semi-Knocked Down) assembly model, where RF modules and mechanical components are imported from Germany for final assembly in India, maintains high standards while ensuring compliance. Although the PLI scheme continues to be applicable, it is not yet a core thrust, with R&S continuing to ramp up its volumes in India.

Critically, local value addition goes beyond physical elements. R&S ensures that software development, integration, and IT infrastructure—from servers to PCs and switches—are locally sourced and installed. In defence and aerospace, where the level of scrutiny is even greater, the capacity to prove indigenous components and technologies is critical to tender wins.

Scaling Operational Capabilities in India

 R&S already has a strong presence in India, covering sales, calibration, maintenance, R&D, IT support, and partial SKD manufacturing. Now, the emphasis is on scaling these functions—specifically sales, service, and application engineering—to address the burgeoning demand across industries.

Mr Mohan underscored the significance of developing local talent, technical and commercial. With its expansion, R&S is also investing in intensive training schemes for its customers and employees to build further product insights and improve long-term results.

 Aviation Security & Industrial Development: Market Tectonics Are Shifting

 India is becoming a hub for cutting-edge security technology, particularly in aviation security. R&S’s whole-body scanners have already passed successful pilots in Bangalore, Delhi, Hyderabad, Goa, and Cochin, and interest is picking up across embassies, parliaments, malls, and high-security auditoriums.

With airport traffic exploding and infrastructure growing fast under India’s civil aviation drive, the opportunity is obvious: high-throughput, high-accuracy security screening isn’t a luxury — it’s a necessity.

In the industrial space, major manufacturers of perfumes, jewellery, and precious metals are turning to technology to mitigate internal theft as well as provide better facility security. Again, here, Mohan observes a willingness to spend money on high-quality, tested technologies.

Product Strategy: Deep RF Expertise, Long-Term Vision

 R&S’s worldwide leadership lies in its core competence in RF and wireless Test instrument product ranges extend as high as 170 GHz, up to 330 GHz with frequency extension. The company is perennially among the top T&M manufacturers worldwide in different product segments, from general purpose oscilloscopes or signal generators and analyzers for applications in multiple industries down to the more specialised segments like EMC test equipment.

R&S considers itself a technology partner for the entire wireless communications ecosystem. Together with chipset suppliers, device and infrastructure OEMs, test houses and network operators, the company has enabled connectivity for generations up to 5G and will continue to do so with 6G and beyond. Solutions already address NTN and the new FR3 frequency range, a candidate for 6G, as well as technologies like Reconfigurable Intelligent Surfaces (RIS) and Integrated Sensing and Communications (ISAC), enabling the next generation of wireless communication.

Beyond wireless, R&S offers test solutions that cover all kinds of applications in electronics testing, making sure digital designs, power electronics, high-speed digital interfaces, RF and microwave components or medical devices meet the highest quality standards.

The solutions also address all trends in the automotive industry, like connectivity and infotainment systems, automotive radar or in-vehicle networks. And the aerospace and defense sectors rely on R&S test instruments. There are also strong relations within the global research and education community.

Privately owned and proudly independent, R&S has the luxury of long-term thinking. As Mohan puts it, “We invest in technologies that may not be profitable today, but are vital for the future.”

Building Ecosystem Trust: Beyond Sales

R&S’s engagement strategy is wonderfully non-transactional. Their Technology Symposiums are not sales pitches — they’re forums for deep technology sharing, establishing trust throughout the ecosystem with participants such as CDOT, Qualcomm, Samsung, and top academic institutions.

Under this model, selling is a spin-off of honest cooperation and learning, not aggressive prospecting. There is also a change in mindset needed in India, Mohan says — especially when launching non-conventional applications of cutting-edge technology, like full-body scanners in civilian or commercial environments.

Rohde & Schwarz isn’t simply sending equipment to India — it’s inserting itself into India’s technology and security ecosystem. Through sophisticated localisation policy, an audacious talent programme, and an evident product and market strategy, the firm stands ready to contribute to shaping the high-tech destiny of India.

As Mohan concludes, “India is not just a market for us — it’s a strategic hub. We’re building for the long term.”

As a Ducati owner, traveler and overall a “I can fix that” guy, in the years I’ve put together a kit of items that are the essentials for fixing or debugging on the field most stuff. The kit comprehend: - Programmable PSU + Leads - LiPo holder + charger + boost to 12V with integrated light - Soldering Iron TS80 (converted to usb C with PD) - Lighter - Shrink Tubes and hotglue - Cable Ties - Wire and solder - Pair of Tweezers - USB C cable - Precision cutter - Multitool with Wire strippers - A “Roll” of thermal resistant tape, copper tape, electrical tape All the textile comes from a pair of broken underwear that I have very unprofessionally sawn together. The kit pretty much always goes with me, if I need to travel via plane I just remove the wire strippers (since they have a knife in them). In the years this thing was useful to me multiple times I do also have a stripped down version that is pocketable. I wanted to share it since I believe could be of use to some. submitted by /u/lollokara [link] [comments]

One classic set you’ll see in most vintage mystery movies is an interrogation room with a “two-way” mirror on one wall. This cool gadget lets the witnesses see the suspects from another room while the suspects can see only themselves. Which direction the two-way mirror works in is determined by which side has more light. The bright side is the suspect’s mirror. The dim side is the witness’s window.

So, what does that have to do with electronics?

This simple design idea describes a two-way current mirror that, in dubious analogy to the optical kind, can mirror or transmit according to whether the input or output side is more positive. It comprises just two BJTs and one diode and is highlighted yellow in Figure 1’s 555 triangle wave VCO.

Figure 1 D1, Q3, and Q4 comprise the two-way current mirror. It passively conducts Q2’s collector current to C1 via Q3’s base-collector when OUT versus C1 is negative, but becomes an active inverting unity-gain current source when OUT goes positive and reverses the polarity.

Wow the engineering world with your unique design: Design Ideas Submission Guide

 Here’s how it works.

Let’s call the D1 node the input, and the C1 node the output. When U1’s OUT pin is low, D1 and the mirror are reversed biased. Now, Q2’s collector current I has nowhere to go except to forward-bias Q3’s base-collector junction, as shown in Figure 2. This connects Q2 to C1 so current I linearly ramps C1 negative.

Figure 2 When OUT goes low, Q4 is off while Q3 saturates and transmits negative current I to C1. Keep Vin < 1 V so Q2 won’t saturate.

When C1 descends to U1’s trigger voltage (1.33 V), OUT transitions positive. This swaps polarity across the mirror, forward biasing it, pulling the emitters of Q3 and Q4 positive relative to C1. Q3 and Q4 then assume the role of a normal active unity-gain current mirror. They now mirror an inverted positive version of I to C1, making it ramp positive, as shown in Figure 3. 

Figure 3 With OUT high, the mirror goes active and inverts I into a positive current to charge C1.

When C1 charges up to U1’s threshold (3.67 V), OUT snaps negative again and a new oscillation cycle begins, finishing output of a (theoretically) symmetrical isosceles triangle waveshape. Keep Vin < 1 V.

Details, including strengths and weaknesses, of the classic two-transistor current mirror can be found in numerous electronics design references.

Of course, a complementary version of the two-way mirror could also be made with NPN transistors. If a current source replaces Q2’s current sink, it will work equally well.

You might be wondering what’s D1 for? When OUT goes low, both transistor emitters are reverse-biased, so no current should flow through the input node anyway. Therefore, D1 is superfluous, right?

Well, no, it isn’t. The reason is summed up in the term “reverse beta.” It turns out that when you reverse-bias a BJT’s base-emitter junction and forward-bias its base-collector, significant current flow is possible—even likely—from collector to emitter. The associated current gain of this upside-down configuration is always way lower than normal beta, but it’s still more than leakage and definitely too significant to ignore. We need D1.

That wraps up the whodunit of the two-way current mirror. Thanks for reading. Sorry if it’s old news to you. It was new news to me when I thought of it, and I hope to show more applications for it in the near future.
