The Mitsubishi QM30HA-H is a single-phase IGBT module engineered for demanding industrial switching applications where thermal stability, low conduction losses, and consistent gate-drive response are critical. Built to Mitsubishi's established H-series design standards, this module integrates IGBT chips with a fast-recovery freewheeling diode in a compact, isolated base package. Its construction supports reliable operation across a broad temperature range, making it a dependable choice for OEM designs and field replacements in high-cycle environments where component failure carries significant downtime cost.

The QM30HA-H sees widespread use in AC motor drives, servo amplifiers, UPS systems, induction heating equipment, and industrial inverters. Its switching performance and isolation characteristics make it suitable for both new equipment designs and direct drop-in replacements in legacy variable-frequency drive platforms. Industries including manufacturing automation, HVAC, material handling, and process control rely on this Mitsubishi module family to maintain uptime across continuous-duty applications where power quality and thermal management are non-negotiable engineering requirements.

Quick Reference: QM30HA-H

Key Features of the QM30HA-H:

• 30A continuous collector current rating with 600V VCES for industrial-grade power handling
• Integrated fast-recovery freewheeling diode minimizes reverse recovery losses in PWM inverter topologies
• Isolated copper base plate provides electrical isolation while enabling direct heatsink mounting for effective thermal management
• Low V_CE(sat) characteristics reduce on-state conduction losses, improving overall inverter efficiency
• Gate-emitter threshold voltage optimized for standard IGBT gate driver circuits operating at ±15V
• Compact, industry-standard package footprint supports straightforward PCB and bus bar integration in OEM and retrofit designs

With a factory lead time of 40 weeks for new production, the QM30HA-H presents a real procurement challenge for maintenance teams managing unplanned failures or engineers building schedules around tight delivery windows. Mitsubishi IGBT modules in this class are frequently constrained at the distribution level, and waiting on factory runs is rarely viable when production lines are at risk. ATI Accurate Technology maintains independent stock of the QM30HA-H specifically to bridge this gap, providing immediate access to genuine OEM components without dependence on manufacturer lead times or broker uncertainty.
