What it is

1200ย V / 400ย A dual half-bridge IGBT module in the low-inductance SEMITRANSย 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: 1200ย V / 400ย A (per module)
  • Topology: Dual IGBT half-bridge with antiparallel CAL diodes
  • Mounting: Screw terminals; isolated copper base (DCB)
  • Package: SEMITRANSย 3 โ€” ~106ย ร—ย 62ย ร—ย 31ย mm
  • Applications: UPS inverters, motor drives, welders, high-power SMPS
Features
  • Soft CAL diodes โ€” low reverse-recovery for cleaner switching.
  • Short-circuit rugged โ€” family-typical tSC โ‰ˆ 10ย ยตs.
  • 4ย kV isolation โ€” terminalsโ†”baseplate hi-pot (AC, 1ย min).
  • Low package inductance โ€” SEMITRANSย 3 bus layout.
