BZW04-37 Description

Short technical summary and product information.

The BZW04-37 is a unidirectional transient voltage suppressor (TVS) diode from Diotec Semiconductor. It features a reverse stand-off voltage of 36.8V, a breakdown voltage of 40.9V, and a maximum clamping voltage of 59.3V at a peak pulse current of 6.7A (10/1000µs waveform). The device can handle 400W peak pulse power and 1W steady-state power dissipation. It also offers a peak forward surge current of 40A (8.3ms half sine-wave) and a forward voltage of less than 3V at 25A.

 

Designed for over-voltage and ESD protection, the BZW04-37 is suitable for commercial and industrial grade applications. It is housed in a DO-15 (DO-204AC) axial leaded through-hole package, weighing approximately 0.4g. The case material is UL 94V-0 rated. Operating junction temperature range is -50°C to 175°C. The device is RoHS3 compliant (exemption 7a), REACH unaffected, and conflict minerals compliant per the datasheet.
