STGSH50M120D

Overview

The STGSH50M120D is an active industrial-grade IGBT module featuring a half-bridge topology within the M series. It integrates two IGBTs and antiparallel diodes in a compact ACEPACK SMIT package. The device supports a collector-emitter voltage of 1200 V and a continuous collector current of 50 A. It operates within a temperature range of -55°C to +175°C junction temperature. Key electrical parameters include a typical saturation voltage of 1.8 V at 50 A and an isolation rating of 3.4 kVrms/min. The component utilizes tape and reel packing and complies with Ecopack2 standards.

Feature Summary

• Optimized for hard switching commutation with low conduction and switching losses
• High short-circuit ruggedness ensuring essential feature reliability
• Positive VCE(sat) temperature coefficient for safe parallel operation
• Soft and fast-recovery antiparallel diode minimizing tail current

Applications

• Industrial motor drives
• Industrial motor control systems
• General-purpose inverters

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm exact packaging and variant specifications. Ensure the ACEPACK SMIT footprint matches your PCB layout requirements. Confirm that the 3.4 kVrms isolation rating meets your safety insulation class needs. Validate thermal management solutions for the 175°C maximum junction temperature limit during design integration.

Selection Notes

Select this component when high power density and surface-mount convenience are required for industrial applications. The M series offers a balanced trade-off between conduction and switching losses suitable for frequencies up to 20 kHz. Consider the positive temperature coefficient for easy paralleling to increase current capacity. Ensure the 1200 V rating provides adequate margin for your DC bus voltage.

Part Context

This part belongs to the STPOWER M series, designed for industrial segments requiring robust performance. It complements other ST IGBTs ranging from 300 V to 1700 V. The ACEPACK SMIT package distinguishes it from through-hole or standard discrete modules by offering a rugged, surface-mounted solution. It fits within ST's portfolio for general-purpose inverters and motor control applications.

Replacement Considerations

Consult official STMicroelectronics substitution guides for direct equivalents. Verify pinout compatibility and thermal characteristics before replacing existing designs with alternative packages or series.
