The CM50TJA-34KA is a high-voltage IGBT module manufactured by Mitsubishi Electric, rated for 50A continuous collector current and a 1700V collector-emitter voltage. Built to Mitsubishi's proven TJA-series architecture, this module delivers low saturation voltage, fast switching characteristics, and integrated gate drive compatibility that meets the demands of modern industrial power electronics. Its robust isolated baseplate construction ensures reliable thermal transfer to heatsink assemblies, making it a dependable choice for engineers designing or maintaining high-voltage converter systems.

The CM50TJA-34KA is well suited for applications including medium-voltage motor drives, traction inverters, UPS systems, induction heating equipment, and industrial power supplies operating at elevated bus voltages. Its 1700V blocking capability makes it particularly valuable in three-level NPC inverter topologies and other architectures where standard 1200V devices lack the necessary voltage margin. Renewable energy converters, grid-tie inverters, and high-power welding systems also benefit from the switching efficiency and ruggedness this module provides.

Key Features of the CM50TJA-34KA:

• 1700V VCES blocking voltage provides essential margin for medium-voltage bus applications and three-level inverter topologies
• 50A rated collector current supports continuous operation in demanding industrial duty cycles
• Low VCE(sat) reduces conduction losses and heat generation, improving overall system efficiency
• Integrated freewheeling diodes optimized for soft recovery, minimizing EMI and switching-related voltage spikes
• Isolated copper baseplate construction facilitates direct heatsink mounting with industry-standard footprint compatibility
• Compatible with standard IGBT gate driver ICs and optocoupler-based drive circuits operating at ±15V gate voltage

With a factory lead time of 99 weeks for new production, the CM50TJA-34KA represents a serious procurement challenge for plant engineers and supply chain teams managing scheduled maintenance, capital projects, or unplanned equipment failures. Mitsubishi's high-voltage IGBT modules in the TJA series have historically experienced extended backlogs due to demand in traction and industrial sectors. Waiting on factory allocation is rarely a viable option when a production line or critical system is at risk. ATI Accurate Technology maintains distributor stock of hard-to-find and long-lead-time modules like the CM50TJA-34KA specifically to bridge this gap.
