Semikron — SKM75GAR123D IGBT Power Module 1200 V • 75 A • GAR Chopper / Booster Configuration • Integrated CAL Freewheel Diode • Isolated Baseplate • SEMITRANS 2
What it is

The Semikron SKM75GAR123D is an industrial-grade 1200 V, 75 A IGBT power module from the SEMITRANS 2 family. Its GAR circuit configuration is designed for chopper and booster applications and combines a high-power IGBT switching element with an integrated fast, soft-recovery CAL diode.

Designed for high-power switching rather than linear operation, the SKM75GAR123D provides a compact power stage for UPS systems, DC-link switching, industrial inverters, motor-drive power electronics and switched-mode power supplies. The electrically isolated copper baseplate simplifies heatsink mounting while maintaining electrical isolation between the power circuit and cooling surface.

Module Representative Applications Replacement Notes
SKM75GAR123D Chopper and booster stages; UPS systems; industrial inverters; motor drives; DC-link switching; switched-mode power supplies Verify 1200 V rating, 75 A current class, GAR circuit topology, gate-drive requirements, terminal configuration, dimensions and thermal characteristics before substitution. GAR, GAL and GB versions are electrically different configurations and should not be treated as interchangeable solely because they share the SEMITRANS housing.
