BZW06-28B

BZW06-28B Description

The BZW06-28B from STMicroelectronics is a high-performance unidirectional Zener TVS diode designed for robust transient voltage suppression in general-purpose applications. Part of the BZW06, TRANSIL™ series, this device offers a 28.2V reverse standoff voltage with a minimum breakdown voltage of 31.4V, ensuring reliable protection against voltage spikes. Its 600W peak pulse power (8/20µs) and 59V maximum clamping voltage at 68A surge current make it ideal for safeguarding sensitive electronics from transient events. Encased in a DO-15 package, the diode features a low 500pF capacitance at 1MHz, minimizing signal distortion in high-speed circuits.
