The CM1000HA-28H-J is a large-format, high-current IGBT module from Mitsubishi Electric, engineered for heavy-duty power electronics applications requiring robust switching performance at elevated voltages and currents. Rated at 1000A collector current and 1400V (VCES), this module features Mitsubishi's H-series IGBT chip technology, which optimizes conduction and switching losses while maintaining thermal stability under continuous high-load operation. The CM1000HA-28H-J is housed in a standard large power module package and integrates a freewheeling diode, making it suitable for inverter topologies without external anti-parallel diode components.

This module is widely deployed in industrial motor drives, traction inverters for rail and heavy transport, high-power UPS systems, induction heating equipment, and medium-voltage converter systems. Its combination of high blocking voltage and kilowatt-class current handling makes it a go-to solution for engineers designing converters in the 500kW–multi-megawatt range. The module is also used in renewable energy systems such as wind turbine converters and utility-scale solar inverters where long-term reliability is critical.

High-power IGBT modules like the CM1000HA-28H-J are frequently subject to long lead times from standard distribution channels due to their specialized manufacturing requirements and sustained demand in industrial and infrastructure markets. OEMs, repair depots, and system integrators facing production holds or field replacements often struggle to source these parts quickly through conventional means. ATI Accurate Technology maintains inventory of hard-to-find, long-lead-time, and obsolete power semiconductors specifically to bridge these supply gaps and keep critical systems running.
