Mitsubishi — CM300DU-12H IGBT Module
600 V •
300 A •
Dual half-bridge (2 IGBTs + antiparallel diodes) •
Isolated baseplate
What it is

600 V, 300 A dual IGBT power module (two-transistor half-bridge) with reverse-connected fast free-wheel diodes
and an insulated baseplate. A proven workhorse for UPS bridges, industrial motor drives, welders, and general-purpose inverters thanks
to low VCE(sat), wide SOA, and straightforward thermal integration.

At-a-Glance
  • Voltage / Current: 600 V / 300 A (600 A peak, pulse)
  • Topology: Dual IGBT half-bridge with antiparallel diodes
  • Mounting: Screw-mount, isolated baseplate
  • Use Cases: UPS inverter/rectifier stages; industrial motor drives; welding/laser power
  • Condition Options: New old stock or tested reclaimed pulls
Features
  • Low conduction loss — VCE(sat) typ. ≈ 1.8–2.1 V (max ≈ 2.5 V) @ 300 A, 25 °C.
  • Fast commutation — super-fast FWDi; short trr for clean bridge operation.
  • Rugged gate rating — ±20 V VGE max with wide RBSOA.
  • Robust isolation — 2.5 kVRMS baseplate test simplifies grounding strategy.
