Vpm2sm Datasheet Guide

This is the recommended mode for the VPM2SM. A reverse bias voltage is applied to the cathode.

The VPM2SM is manufactured by several brands (Littelfuse, ON Semi, Vishay, STMicroelectronics, and Chinese brands like Brightking). However, there is no single "VPM2SM" JEDEC standard number – it is often a proprietary or distributor-specific part code. vpm2sm datasheet
