The 36MT120 is an International Rectifier IGBT module rated at 36 amperes and 1200 volts, built to deliver reliable high-frequency switching performance in a rugged, industry-standard module format. With its 1200V blocking voltage and low on-state losses, this device is engineered for applications where thermal efficiency and switching precision are non-negotiable. The module's robust construction supports demanding duty cycles in both continuous and pulsed operation, making it a proven choice for engineers designing or maintaining industrial power electronics platforms that require long-term dependability.

The 36MT120 sees widespread use across industrial and commercial power conversion equipment, including variable frequency motor drives, solar inverters, UPS systems, induction heating equipment, and welding power supplies. Its 1200V rating provides necessary headroom for line-connected three-phase systems, while the 36A current rating suits mid-power drive and converter topologies. Retrofit and field replacement applications are common, particularly in legacy industrial machinery where original equipment manufacturers have long discontinued active support but the underlying power stage design remains serviceable and cost-effective to maintain.

Quick Reference: 36MT120

Key Features of the 36MT120:

• 1200V collector-emitter breakdown voltage providing robust margin for 480/600VAC three-phase line-connected applications
• 36A continuous collector current rating suited for mid-range drive and inverter power stages
• Low V_CE(sat) for reduced conduction losses and improved thermal efficiency at operating current levels
• Integrated freewheeling diode optimized for fast recovery, minimizing reverse recovery losses during hard-switching commutation
• Industry-standard module footprint enabling direct drop-in replacement in existing PCB and heatsink assemblies
• Isolated baseplate construction simplifying heatsink mounting and electrical isolation in multi-module configurations

With a current factory lead time of 99 weeks for new production, sourcing the 36MT120 through standard distribution channels is not a viable option for most maintenance and procurement teams facing unplanned downtime or scheduled outages. International Rectifier's absorption into Infineon Technologies has further complicated the availability picture for legacy IR module part numbers. Engineers managing aging equipment or building service inventory for installed base systems cannot afford to wait nearly two years for critical power switching components — making access to stocked, new OEM inventory essential.
