163CMQ100

Overview

The Vishay 163CMQ100 is a Schottky rectifier module featuring a dual anode common cathode configuration housed in a TO-249AA package. It provides a maximum DC reverse voltage of 100 V and supports a maximum average forward current of 160 A per leg under specified conditions. The device operates reliably within a junction temperature range of -55 to 175 °C, utilizing proprietary barrier technology for low reverse leakage at elevated temperatures.
