BZW04-9V4B Description

Short technical summary and product information.

The BZW04-9V4B is a bidirectional transient voltage suppressor (TVS) diode designed for overvoltage and ESD protection in general purpose applications. It features a standoff voltage of 9.4 V and a breakdown voltage of 15.6 V, providing a clamping response for transient events. The device is rated for 400 W peak pulse power (10/1000 µs waveform) and 25.7 A peak pulse current, with a steady state power dissipation of 1 W. It offers very fast response time and operates over a junction temperature range of -55°C to 175°C.

 

This TVS diode is housed in a through-hole DO-204AL (equivalent to DO-41) axial lead package, weighing approximately 0.4 g. The case material is UL 94V-0 rated, and the device is lead-free and halogen-free per the datasheet. It is suitable for general purpose overvoltage protection, free-wheeling diode circuits, and ESD protection in commercial and industrial grade designs.
