What it is

1200ย V, 400ย 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: 1200ย V / 400ย 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 โ€” VCE(sat) (typ.) โ‰ˆย 2.3ย V @ 400ย A, 25ย ยฐC.
  • Rugged diode โ€” Fast FWD with low VF and short trr for clean commutation.
  • Thermally efficient โ€” RthJC โ‰ˆย 0.04ย ยฐC/W (IGBT), โ‰ˆย 0.12ย ยฐC/W (diode).
  • Service-friendly โ€” Common Fuji S-series single-pack footprint.
