The Mitsubishi CM100DY-34A is a dual (chopper) configuration IGBT module rated for 100A continuous collector current and 1700V collector-emitter voltage. Built on Mitsubishi's proven 7th-generation IGBT die technology, this module delivers low saturation voltage, fast switching characteristics, and integrated freewheeling diodes in a compact, isolated baseplate package. It is engineered for reliability under high thermal stress, making it a dependable choice for high-voltage power conversion stages where efficiency and switching precision are non-negotiable.

The CM100DY-34A sees widespread deployment in industrial AC motor drives, regenerative braking systems, UPS inverters, induction heating equipment, and railway traction converters. Its 1700V blocking capability makes it particularly well-suited for applications connected to 690VAC or higher bus voltages where standard 1200V devices lack sufficient margin. Maintenance engineers replacing failed modules in legacy servo drives or custom inverter platforms frequently specify this part, and procurement teams supporting MRO or capital equipment builds rely on spot inventory to avoid costly production halts.

Key Features of the CM100DY-34A:

• 1700V VCES rating provides robust voltage margin for 690VAC and higher bus voltage systems
• 100A continuous collector current with high short-circuit withstand capability for fault-tolerant designs
• Integrated anti-parallel freewheeling diodes eliminate external diode components and simplify PCB layout
• Low VCE(sat) reduces conduction losses and thermal dissipation at full load
• Isolated copper baseplate construction ensures electrical isolation while maximizing thermal conductivity to heatsink
• Industry-standard footprint and pinout compatible with equivalent dual IGBT module form factors for drop-in replacement

With a published factory lead time of 34 weeks, waiting on new production of the CM100DY-34A is rarely a viable option for engineers facing an unplanned equipment failure or a time-sensitive build schedule. Mitsubishi 1700V-class modules in this current range are among the most lead-time-sensitive devices in the power semiconductor market. Facilities running aging drives or custom inverter platforms built around this module cannot afford to treat it as a just-in-time purchase. Maintaining a spare on the shelf or sourcing immediately from an authorized stocking distributor is the only reliable strategy to protect uptime.
