BZW04-376B ST Transient Voltage Suppressors (TVS)

The BZW04-376B is a 400W bidirectional Transil TVS diode from STMicroelectronics in DO-41 through-hole package, featuring 376V breakdown voltage for high-voltage circuit transient protection. For selection, verify reverse standoff voltage, breakdown voltage range, clamping voltage at peak pulse current, peak pulse power of 400W for 10/1000µs waveform, low leakage current, fast response time, and operating junction temperature from -55°C to +150°C. Bidirectional configuration provides symmetrical protection for AC applications or bipolar signal lines. Features include planar technology, compliance with IEC 61000-4-2/4-4/4-5 standards, and UL recognition. Ideal for voltage spike protection in industrial power supplies, high-voltage AC-DC power supply lines, communication equipment, I/O interfaces, and any system requiring 400W bidirectional transient suppression for high-voltage rails.
