VS-VSKV91/04

SCRs - Modules Overview

The Vishay VS-VSKV91/04 is a thyristor module featuring two SCRs with common anodes, rated for a maximum repetitive peak reverse voltage of 400 V. It supports a maximum average on-state current of 95 A and a continuous RMS current of 150 A. The device utilizes the AAP Gen 7 (TO-240AA) package with an exposed direct bonded copper substrate to achieve low thermal resistance. Designed for industrial applications, it operates within a junction temperature range of -40 °C to +125 °C.
