AEC-Q101 Qualified Devices Save Board Space While Offering High Stability for Automotive Applications

Vishay Intertechnology, Inc. introduced a new series of uni/bidirectional 1500 W surface-mount PAR transient voltage suppressors (TVS) in the SMB (DO-214AA) package. To meet the demands of automotive applications, the Vishay General Semiconductor T15BxxA and T15BxxCA series are AEC-Q101 qualified and offer high temperature operation to +185 °C.

Compared to TVS in the SMC (DO-214AB) package, the Automotive Grade devices released today provide a 58 % smaller footprint to save board space and lower system costs. The unidirectional T15BxxA series offers extremely stable breakdown voltages from 12 V to 51 V, while the bidirectional T15BxxCA series provides breakdown voltages from 12V to 100 V. The devices offer excellent clamping capability — 17.0 V to 70.1 V for the T15BxxA and 17.0 V to 137 V for the T15BxxCA — and very fast response times.

The TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. Typical applications will include lighting, electro-mechanical brake (EMB), and fuel pump control; 48 V DC/DC converters and inverters; integrated starter generators, BMS, vehicle control units (VCU), and on-board chargers; and telematics control units (TCU) for audio, electronic stability control (ESC), and radar sensors.

The devices meet MSL level 1 standards per J-STD-020 and are RoHS-compliant and halogen-free.

I made this dummy PCB on my 3D printer before submitting a front panel board to the PCB manufacturer. Turned out to be a nice method to avoid part alignment mishaps. The accuracy was in fact down to about 0.1 mm 💪 submitted by /u/Party-Butterfly-4857 [link] [comments]

I had to add a bypass set of capacitors at the voltage divider that was feeding the + input of the opamp. I also had to add a low - pass filter on the signal input, especially if I attempted to use my phone as audio input it had a lot of noise on it and apparently the phone expects a somewhat low impedance or it will get even noiser. I then also had to put a capacitor / resistor network across the feedback resistor to enforce lowering the gain at higher frequencies which prevented the opamp from oscillating during large signal swings. And now it is fully functional, mounted to a heatsink. Puts out about 14watts into 4 ohms at 30volts supply. Will do almost 20 watts into 2ohm load. I will be switching the potentiometer out for a smaller PCB style one and also integrating the input filter directly on the board soon. submitted by /u/Perfect-Campaign9551 [link] [comments]

In this article, we'll investigate how varying the amplitude and frequency of the modulating tone impacts the bandwidth of FM signals. We'll also compare the modulation index in AM and FM schemes.
