Offered in TO-263 (D²PAK) Package, Device Combines High Pulse Absorption to 15 J/0.1 s With Power Dissipation of 35 W

Vishay Intertechnology, Inc. announced that it has extended its D2TO35 series of surface-mount thick film power resistors with a new AEC-Q200 qualified device that delivers higher pulse absorption up to 15 J/0.1 s. Offered in the TO-263 (D²PAK) package, the Vishay Sfernice D2TO35H provides high power dissipation of 35 W at a +25 °C case temperature.

The Automotive Grade device released today features a unique design that provides 30 % higher energy absorption than the standard D2TO35 resistor for enhanced protection against short transient pulses. The result is more stable operation in high stress environments, reducing the risk of failure and improving overall system reliability while requiring fewer components to save board space, simplify layouts, and reduce overall solution costs.

The D2TO35H offers high temperature operation to +175 °C; a broad range of resistance values from 1 Ω to 14 kΩ, with tolerances down to ± 2 %; and thermal resistance of 4.28 °C/W. The device will serve as the active discharge, discharge, or precharge resistor for controls, 48 V board nets, BMS, fuel cells, and on-board chargers for HEVs, EVs, and low speed electric vehicles; energy monitoring and metering systems; agricultural vehicles and farm equipment; industrial motor drives, welding equipment, and power tools; and military weapons guidance systems.

The RoHS-compliant resistor offers a non-inductive design and is solder reflow secure at 270 °C/10 s.

Sycamore-W, an ultra-thin near-field MEMS speaker from xMEMS, brings premium audio to smartwatches and fitness bands. With dimensions of just 20×4×1.28 mm, it reduces speaker package volume by up to 70%, freeing space within wrist-worn devices for additional biometric sensors or larger batteries. At just 150 mg, Sycamore-W also minimizes weight impact in space-constrained wearables.

Compared to conventional coil speakers—typically 3 mm to 4 mm thick and weighing up to 3 grams—Sycamore-W’s slim profile and low mass significantly reduce bulk. The lighter design minimizes strain and improves comfort for all-day wear.

With solid-state durability, the MEMS speaker offers component-level IP58-rated ingress protection and withstands mechanical shocks up to 10,000 g. It delivers zero phase delay and improved low-frequency response compared to dynamic drivers, exhibiting 1st-order decay—where output falls off more gradually (1/f vs 1/f², or –20 dB vs –40 dB from 2 kHz to 20 Hz)—for stronger bass performance.

Samples of the Sycamore-W are available now to early access customers, with volume production slated for Q2 2026.

The LSM6DSV320X inertial measurement unit (IMU) from ST features dual accelerometers for activity tracking up to 16 g and impact detection up to 320 g. To support edge computing, it integrates a machine-learning core for context awareness with exportable AI features, along with embedded functions such as a finite state machine for configurable motion tracking.

Housed in a compact 3×2.5-mm module, the IMU suits applications ranging from wearables and consumer medical devices to smart home and vehicle crash-detection systems. In addition to the 3-axis accelerometers, it includes a gyroscope with a range of up to ±4000 dps. All three sensors are fully synchronized to simplify application development.

Other features include an embedded sensor fusion low-power algorithm for spatial orientation and an adaptive self-configuration (ASC) function. With ASC, the sensors automatically adjust their settings in real time when a specific motion pattern or machine-learning core signal is detected—without requiring host processor intervention.

In production now, the LSM6DSV320X is supported in the Edge AI Suite and will be added to AIoT Craft by the end of 2025.

Qorvo has expanded its QPG6200 portfolio of low-power wireless SoCs supporting Matter over Thread, Zigbee, and Bluetooth LE. Featuring the company’s ConcurrentConnect technology, the devices enable seamless multiprotocol communication for smart home, industrial automation, and other IoT applications.

Based on the previously announced QPG6200L—now in production with leading smart home OEMs—the QPL6200J, QPL6200M, and QPL6200N deliver up to 20 dBm transmit power in a compact QFN package. Output power is software-configurable to meet global regulatory requirements. All devices are powered by an Arm Cortex-M4F processor running at up to 192 MHz, with 2 MB of nonvolatile memory and 336 kB of RAM.

The table below highlights key differences.

A PSA Certified Level 2 development kit based on the QPG6200L is available now, with the full device family scheduled for production in the third quarter of 2025.

Anritsu’s Site Master cable and antenna analyzers are now available with optional vector network analyzer (VNA) and vector voltmeter (VVM) capabilities. These additions extend their use to field testing of filters and amplifiers, as well as maintenance of radar and antenna systems, including VHF omnidirectional range (VOR) and instrument landing system (ILS) navigation equipment.

The two-port, one-path VNA covers 5 kHz to 4 GHz or 6 GHz. Calibration options include standard open/short/load accessories, the one-step InstaCal module, or factory ReadyCal for immediate measurements. With over 100 dB of dynamic range and –45 dBm to +9 dBm output power, it supports testing of filters, diplexers, and amplifiers in communication base stations. A 380-µs/point sweep speed accelerates alignment and tuning.

The VVM performs cable phase matching in complex phased array antenna systems, such as VOR/ILS systems at major airports. A table display of individual results simplifies phase matching of multiple cables.

The VNA and VVM options for the Site Master MS2085A and MS2089A portable analyzers are now available, with existing instruments eligible for upgrade.

Infineon’s CoolGaN 650-V G5 bidirectional switch (BDS) integrates two switches in a single device to actively block current and voltage in both directions. Its monolithic common-drain design with a double-gate structure, based on gate injection transistor technology, improves efficiency, reduces die size, and replaces conventional back-to-back configurations.

The GaN switch simplifies cycloconverter designs by enabling single-stage power conversion, eliminating the need for multiple conversion stages. In microinverters, it supports higher power density and a lower component count. It also enables advanced grid functions such as reactive power compensation and two-way power flow.

The CoolGaN 650-V G5 BDS is offered in a TOLT package with RDS(on) values of 110 mΩ and 55 mΩ. It is now open for ordering, with samples of the 110-mΩ version available.

My first encounter several decades ago with a pillar of modern technology yielded more than just one lesson.

NEREM 1967 was the IEEE Northeast Electronics and Engineering Meeting held at the Sheraton-Boston Hotel and the War Memorial Auditorium in Boston, MA, from November 1 to 3, 1967. I was there, although most of the engineering population in the Northeastern United States could probably have shared that claim back then; it was perhaps the busiest mass of human activity I’ve ever encountered in one common environment.

The display booths were extremely elaborate, but the one thing I couldn’t help noticing was that all these demonstrations of test equipment sported a constellation of these strange but intense little red lights that, in many cases, formed numbers, but some of which had to be viewed from pretty much straight on or the light would vanish.

Of course, they were early versions of LEDs.

Shortly afterward, having learned what an LED was, I obtained a sample. It was a Monsanto type MV-50 (Figure 1), which, when I wired it up, I saw its little red light. At the same time, a separate light of realization went off in my head as I finally understood what it was that I’d been seeing all over the place at the NEREM show.

Next, I began studying some LED datasheets.

One parameter that kept appearing at the forefront of many datasheets was light output rated in candelas. The candela is a unit of luminous intensity or luminous power per unit of solid angle, and the numbers for that parameter rivaled each other from product to product.

However!!

The physical dimensions of some LEDs of that era were really quite small and some of them had very directional and limited light output patterns. Even though the candela ratings could be “impressive”, the total light output from some of them was, if you’ll forgive me for being judgmental, puny.

The stress that was placed on the high intensity rating seemed like an exercise in specmanship. Still, if you want to know how far LED technology has come in the ensuing fifty-odd years, take a late-night walk-through Times Square in Manhattan and don’t forget your sunglasses.
