APTGF400U120D4G

Overview

The APTGF400U120D4G is a single-switch Non-Punch Through (NPT) Fast IGBT power module manufactured by Microsemi. It features an isolated D4 package with a collector-emitter breakdown voltage of 1200 V and a continuous collector current rating of 510 A at Tc = 25°C, decreasing to 400 A at Tc = 80°C. The maximum power dissipation is 2500 W at Tc = 25°C. The integrated parallel diode exhibits a forward voltage of 2.1 V at 400 A and 25°C. Electrical characteristics include a gate threshold voltage ranging from 4.5 V to 6.5 V and a maximum gate-emitter voltage of ±20 V. The junction-to-case thermal resistance is 0.05 °C/W for the IGBT and 0.09 °C/W for the diode.
