QM200HA-HK IGBT NEW QM200HAHK

Product Overview

The Mitsubishi QM200HA-HK High Power Switching Insulated Type Transistor Module is a robust, industrial-grade power semiconductor device designed for high-current switching applications. Part of Mitsubishi's QM series power transistor family, the QM200HA-HK is configured as a Darlington NPN silicon power transistor pair with an integrated fast recovery freewheeling (FWD) diode — all in an electrically insulated package with a metal baseplate for direct heatsink attachment.

With a collector current rating of 200A and a collector-emitter voltage rating of 600V, this module is engineered for demanding environments such as industrial motor drives, uninterruptible power supplies (UPS), constant voltage constant frequency (CVCF) inverters, CNC/NC machine tool controls, and arc welding equipment. The insulated package construction eliminates the need for electrical isolation between the module and the heatsink, reducing thermal resistance and simplifying mechanical assembly in high-density power electronics enclosures.

Darlington Transistor vs. IGBT: Why QM200HA-HK Uses Darlington Architecture

The QM200HA-HK uses a Darlington pair (Darlington configuration) rather than an IGBT architecture. Key differences:

• Current Drive: Darlington transistors are current-controlled devices — a small base current controls a much larger collector current. The internal Darlington pair amplifies this relationship to achieve hFE ≥ 75

• Voltage Rating: With VCEX = 600V, the QM200HA-HK handles DC bus voltages up to approximately 400-500V in typical inverter designs — suitable for 220V/380V AC motor drive applications

• Switching Speed: Fall time of ≤3 µs makes this module suitable for switching frequencies up to approximately 10-20 kHz — adequate for most industrial motor drive and UPS applications

• Thermal Management: The metal baseplate and insulated construction allow direct attachment to a heatsink with minimal thermal resistance, enabling sustained high-current operation

• Integrated Freewheeling Diode: The built-in fast recovery diode handles inductive kickback from motor windings during switching transitions, protecting the transistor from voltage spikes

Thermal Management Guidance

Proper thermal design is essential for reliable operation of the QM200HA-HK:

• Heatsink Required: The module must be mounted to an appropriately sized heatsink. The rated collector dissipation of 800W assumes adequate heatsink cooling with thermal compound

• Thermal Resistance: Mount with thermal interface material (thermal grease or phase change compound) between the module baseplate and heatsink for optimal heat transfer

• Air Cooling: Forced air cooling (fan) is recommended for continuous operation above 50% of rated current in enclosed panels

• Temperature Monitoring: Consider adding a temperature sensor or thermocouple near the module's baseplate to implement thermal cutback protection in the drive circuit

• Maximum Junction Temperature: Do not exceed Tj(max) = +150°C. Design thermal system to keep junction temperature below +125°C for reliable long-term operation
