APT60DQ120LCTG

Overview

The APT60DQ120LCTG is a dual ultrafast soft recovery rectifier diode module manufactured by Microsemi Corporation. It features two independent elements in a common cathode configuration within a TO-264 package. The device supports a maximum repetitive reverse voltage of 1200V and an average forward current of 60A per leg at a case temperature of 103°C. Key electrical characteristics include a maximum forward voltage of 3.35V at 120A, a maximum reverse leakage current of 500µA at 1200V and 125°C, and a junction capacitance of 37pF at 200V reverse bias. The module is rated for non-repetitive surge currents up to 540A and avalanche energy of 20mJ.
