BZW50-15

BZW50-15 Description

The BZW50-15 from STMicroelectronics is a unidirectional Zener-type TVS diode designed for general-purpose transient voltage suppression in electronic circuits. Part of the BZW50, TRANSIL™ series, it offers robust protection with a 15V reverse standoff voltage and a 16.6V minimum breakdown voltage, ensuring reliable operation under transient conditions. Its 35V maximum clamping voltage @ Ipp and 5kW peak pulse power (8/20µs) make it highly effective at diverting high-energy surges, safeguarding sensitive components. With a low capacitance of 13500pF @ 1MHz, it minimizes signal distortion, making it suitable for high-speed applications. The device is RoHS3 compliant and features a through-hole mounting for easy integration.
