Mitsubishi QM100DY-H IGBT Power Transistor Module

The Mitsubishi QM100DY-H is an advanced insulated-gate bipolar transistor (IGBT) power module designed for high-power switching applications. Rated at 600V collector-emitter voltage and 100A collector current, it integrates two IGBT switches with freewheeling diodes in a single compact, insulated package. The module is widely used in industrial inverters, servo drives, DC motor controllers, NC equipment, and welding machines where efficient and reliable power conversion is required.

Dual IGBT Configuration

The QM100DY-H contains two IGBT switches in a dual configuration, making it suitable for half-bridge and full-bridge power converter topologies. Each IGBT is paired with an integrated freewheeling diode that provides reverse current protection, essential for inductive loads such as motor windings. The insulated packaging simplifies heat sink mounting and ensures electrical safety, with an isolation voltage rating of 2500 V between module terminals and the base plate.

High-Power Switching Performance

With a 100A collector current rating and 620W power dissipation capacity, the QM100DY-H can handle substantial power levels while maintaining thermal stability. The module is optimized for high-frequency switching applications, making it suitable for modern pulse-width modulation (PWM) inverters and servo drives. The wide junction temperature range of -40°C to +150°C ensures reliable operation in demanding industrial environments.

Application Domains

The QM100DY-H is used in AC and DC motor drives, industrial inverters for pump and fan control, servo drives for precision positioning, CNC machine tool spindle drives, and welding equipment power stages. It is also suitable for uninterruptible power supplies (UPS) and switching power supplies requiring high current capacity.
