Fuji Electric — 1MBI400S-120 IGBT Module
1200 V •
400 A •
Single IGBT (1-pack) with antiparallel fast diode •
Isolated baseplate
What it is

1200 V, 400 A single IGBT module widely used in UPS bridges, motor drives, and high-power converters.
Low switching/conduction loss, fast free-wheel diode, and an isolated base simplify thermal and EMC design.

At-a-Glance
  • Voltage / Current: 1200 V / 400 A (module rating)
  • Topology: Single IGBT (1-pack) with antiparallel diode
  • Mounting: Screw-mount, isolated baseplate
  • Use Cases: UPS inverter/rectifier; industrial motor drives; DC-link choppers; welders/laser supplies
  • Condition Options: New old stock or tested reclaimed pulls
Features
  • Low conduction loss — VCE(sat) (typ.) ≈ 2.3 V @ 400 A, 25 °C.
  • Rugged diode — Fast FWD with low VF and short trr for clean commutation.
  • Thermally efficient — RthJC ≈ 0.04 °C/W (IGBT), ≈ 0.12 °C/W (diode).
  • Service-friendly — Common Fuji S-series single-pack footprint.
