MSCGLQ75DDU120CTBL3NG

Overview

The MSCGLQ75DDU120CTBL3NG is a double dual common emitter high-speed IGBT4 power module manufactured by Microchip Technology. It features a 1200 V collector-emitter voltage rating and supports a continuous collector current of 160 A at 25 °C, decreasing to 75 A at 80 °C. The device integrates SiC Schottky diodes with zero reverse recovery characteristics. Key electrical parameters include a maximum gate-emitter voltage of ±20 V, a typical collector-emitter saturation voltage of 2.05 V at 75 A, and a total power dissipation capability of 470 W. The junction-to-heatsink thermal resistance is specified at 0.318 °C/W.

Feature Summary

• High speed IGBT4 technology providing low voltage drop, low leakage current, and reduced switching losses.
• Integrated SiC Schottky diodes offering zero reverse and forward recovery with temperature-independent switching behavior.
• Kelvin emitter configuration designed for simplified driver circuit implementation.
• Si3N4 substrate combined with thick copper layers to enhance thermal performance.

Applications

• High reliability power systems
• AC switches

Procurement Notes

Verify the specific datasheet revision (DS00004078A) against the manufacturer's official website before finalizing design specifications. Confirm that the package weight of 32.5 g and mounting torque requirements between 0.7 and 0.9 N.m align with the mechanical constraints of the target heatsink assembly. Ensure electrostatic discharge handling procedures are strictly followed during component installation.

Selection Notes

Select this module when designing circuits requiring a 1200 V blocking capability with integrated fast-recovery diodes. The 160 A continuous current rating at 25 °C allows for robust operation in high-power applications. Consider the 0.318 °C/W thermal resistance for heatsink sizing calculations. Verify that the operating junction temperature range of -55 °C to 175 °C meets the environmental demands of the intended system.
