Semikron — SKM400GB123D IGBT Module 1200 V • 400 A • Dual half-bridge (2 IGBTs + antiparallel CAL diodes) • Isolated baseplate (SEMITRANS 3)
What it is

1200 V / 400 A dual half-bridge IGBT module in the low-inductance SEMITRANS 3 package. Features soft-recovery
CAL free-wheel diodes and an insulated DCB baseplate for straightforward heatsinking in UPS, drives, and high-power SMPS.

At-a-Glance
  • Voltage / Current: 1200 V / 400 A (per module)
  • Topology: Dual IGBT half-bridge with antiparallel CAL diodes
  • Mounting: Screw terminals; isolated copper base (DCB)
  • Package: SEMITRANS 3 — ~106 × 62 × 31 mm
  • Applications: UPS inverters, motor drives, welders, high-power SMPS
Features
  • Soft CAL diodes — low reverse-recovery for cleaner switching.
  • Short-circuit rugged — family-typical tSC ≈ 10 µs.
  • 4 kV isolation — terminals↔baseplate hi-pot (AC, 1 min).
  • Low package inductance — SEMITRANS 3 bus layout.
