The Mitsubishi CM300EXS-24S is a 300A, 1200V IGBT module engineered for high-efficiency power switching in industrial-grade applications. Built to Mitsubishi's EXS-series standards, this module integrates fast-switching IGBT chips with freewheeling diodes optimized for hard-switching converter topologies. Its combination of high current capacity, robust isolation voltage, and low saturation voltage (V_CE(sat)) makes it a reliable choice for engineers designing or maintaining high-power inverter systems where thermal management and switching performance are non-negotiable.

The CM300EXS-24S is widely deployed in AC and DC motor drive systems, industrial servo drives, UPS systems, induction heating equipment, and traction inverters. Its 1200V blocking voltage provides the headroom needed for three-phase 480V bus applications with standard derating margins. OEMs and end-users in steel processing, paper manufacturing, oil and gas, HVAC, and renewable energy generation rely on this module as a core switching element in both legacy installations and current-generation power conversion platforms.

Quick Reference: CM300EXS-24S

Key Features of the CM300EXS-24S:

• 1200V collector-emitter breakdown voltage with 300A continuous collector current rating for high-power switching stages
• Low V_CE(sat) characteristics reduce conduction losses and improve overall inverter efficiency across the load range
• Integrated freewheeling diodes with optimized reverse recovery characteristics minimize switching stress in hard-switching topologies
• High isolation voltage between baseplate and terminals supports safe integration into multi-level or multi-phase converter assemblies
• EXS-series package designed for direct baseplate mounting to heatsink, enabling efficient thermal coupling in thermally demanding environments
• Compatible with standard IGBT gate drive circuits (typically 15V/-8V or 15V/-15V) simplifying drop-in replacement in existing drive platforms

With a current factory lead time of 99 weeks on new production orders, the CM300EXS-24S represents exactly the kind of long-lead, hard-to-source component that halts production lines and stretches maintenance budgets. Whether you're managing a critical repair, building safety stock, or sourcing for a scheduled overhaul, waiting on factory allocation is not a viable option. ATI Accurate Technology maintains inventory of difficult-to-find IGBT modules like the CM300EXS-24S specifically to bridge that gap — keeping your equipment running and your procurement timeline intact without compromise on part quality or authenticity.
