BZW04-5V8B Description

Short technical summary and product information.

The BZW04-5V8B is a bidirectional Transil TVS diode designed for transient overvoltage protection. It features a peak pulse power dissipation of 400W (10/1000µs waveform) with a stand-off voltage of 5.8V. The breakdown voltage ranges from 6.45V to 10V at 10 mA, and the clamping voltage is 10.5V at 38A peak pulse current (10/1000µs) and 13.4V typical at 174A (8/20µs).

 

This device offers a low clamping factor and fast response time, making it suitable for protecting voltage-sensitive circuits. Typical capacitance is 3500 pF at 1 MHz. The leakage current is 1000 µA maximum at 5.8V. It is rated for operation over a junction temperature range of -65°C to 175°C.

 

The BZW04-5V8B is packaged in a DO-204AC (DO-15) axial leaded through-hole package, suitable for PCB mounting. It is UL recognized per the datasheet. The device is bidirectional, providing protection for both positive and negative transients.
