Mitsubishi QM20DX-H Power Bipolar Transistor, IGBT Module

The QM20DX-H is a Mitsubishi power bipolar transistor, listed under the IGBT Modules subcategory of semiconductors. The lifecycle stage is noted as mature, meaning the part remains in active distribution but is not a new-design target. Typical applications include power switching in industrial drives, inverters, and power supplies. No direct replacement or pin-compatible alternative is known; confirm fit by cross-referencing the module footprint with your application's requirements.
