MBR6045WT

Diode Arrays Overview

The Vishay MBR6045WT is a center tap Schottky rectifier featuring two independent legs in a TO-247AC package. It provides a maximum average forward current of 30 A per leg (60 A total) and a repetitive peak reverse voltage of 45 V. The device operates at junction temperatures up to 150 °C with a typical forward voltage drop of 0.55 V at 30 A and 125 °C. Maximum non-repetitive surge current reaches 2900 A for a 5 µs sine pulse, while thermal resistance from junction to case is 1.0 °C/W per leg.
