BZW50-39 Description

Short technical summary and product information.

The BZW50-39 is a 5000W (5kW) unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It features a reverse standoff voltage of 39V and a clamping voltage of 90V, providing robust overvoltage protection for sensitive electronics.

 

This Zener-based TVS diode can handle a peak pulse current of 667A under an 8/20µs waveform. It is designed for general purpose applications and is not intended for power line protection. The device operates as a single-channel unidirectional protector.

 

Packaged in a through-hole R-6 axial leaded package, the BZW50-39 is suitable for wave soldering and manual assembly. The axial lead style facilitates easy mounting on printed circuit boards or in wiring harnesses. The junction capacitance is 4800pF at 1MHz, which should be considered for high-speed signal lines.
