BZW04-376BRL Description

Short technical summary and product information.

The BZW04-376BRL is a bidirectional transient voltage suppression (TVS) diode from STMicroelectronics designed for general-purpose overvoltage protection. It features a reverse standoff voltage of 376V and a maximum clamping voltage of 603V at the rated peak pulse current of 800mA (10/1000µs waveform). The device can handle 400W of peak pulse power, making it suitable for protecting sensitive electronics from voltage transients.

 

This TVS diode is housed in a DO-204AC (DO-15) axial-lead through-hole package, which allows for easy insertion in PCB designs or point-to-point wiring. It offers a single bidirectional channel, eliminating the need for orientation in AC or bidirectional signal lines. The typical capacitance is 35pF at 1MHz, which is appropriate for general-purpose protection applications where signal integrity is not severely impacted.

 

Designed for general-purpose use, the BZW04-376BRL is commonly employed in power supply lines, industrial equipment, and telecommunications circuits where protection against inductive load switching or lightning-induced transients is required. The through-hole mounting provides robust mechanical attachment in high-reliability or high-vibration environments.
