what this module carries
The Mitsubishi QM200HA2H is a 4-pole transistor module with 200 A switching current and 1000 V collector-emitter voltage. The 4-pole arrangement suits half-bridge or full-bridge topologies. Operating temperature range -40 °C to 150 °C suits industrial cabinets and outdoor enclosures. Dimensions are 108 x 62 x 36 mm.
peer module – QM200HA-2H
The QM200HA-2H shares identical electrical ratings and the same 108 x 62 x 36 mm footprint. The difference? On the secondary market the QM200HA-2H often turns up as a used pull. If you're sourcing for a new build, the QM200HA2H is the order code to quote. If you're chasing a last-minute replacement and the -2H is what's on the shelf, it will drop in electrically and mechanically — same 200 A, same 1000 V, same 4-pole arrangement.
Plan a proper heatsink — 200 A through a silicon junction generates heat that a DIN-rail clip won't shed. The baseplate dimensions are 108 x 62 x 36 mm. Gate drive needs to be isolated; a 4-pole module means two separate gate pairs if it's a half-bridge, or four independent gates for a full-bridge.
