The Mitsubishi CM50E3U-24H is a 50A, 1200V IGBT module engineered for high-frequency switching applications in industrial power electronics. Built to Mitsubishi's proven E3U-series standard, this module integrates insulated gate bipolar transistor technology with a fast-recovery freewheeling diode in a robust, isolated baseplate package. It offers low saturation voltage, controlled tail current, and a thermally efficient construction that supports reliable continuous operation in harsh industrial environments—making it a preferred choice for design engineers and maintenance teams managing demanding drive and inverter platforms.

The CM50E3U-24H is widely deployed in variable frequency drives (VFDs), AC servo amplifiers, uninterruptible power supplies (UPS), solar inverters, induction heating equipment, and general-purpose industrial inverters. Its 1200V blocking voltage and 50A continuous collector current rating make it well-suited for three-phase motor control systems operating from 400V to 690V bus voltages. The module's isolated baseplate simplifies heatsink mounting and electrical isolation in multi-axis drive cabinets, reducing assembly complexity while maintaining safe thermal dissipation across the full operating current range.

Key Features of the CM50E3U-24H:

• 1200V VCES and 50A IC rating suitable for 400V–690V three-phase industrial drive applications
• Low VCE(sat) reduces conduction losses, improving system efficiency at rated and partial loads
• Integrated fast-recovery anti-parallel freewheeling diode minimizes switching losses during commutation
• Isolated copper baseplate construction enables direct heatsink mounting without additional isolation hardware
• Controlled tail current characteristic reduces EMI and di/dt stress on gate drive circuitry during turn-off
• Compact module footprint compatible with standard Mitsubishi E3U-series mechanical and electrical footprints, simplifying form-fit-function replacement

With a factory lead time of 38 weeks for new production, the CM50E3U-24H presents a serious procurement challenge for facilities managing unplanned downtime or time-sensitive production schedules. Mitsubishi IGBT modules in this voltage and current class are frequently subject to extended allocation queues, and obsolescence risk increases as platforms age. Sourcing from a stocking distributor eliminates that exposure entirely. ATI Accurate Technology maintains inventory of hard-to-find, long-lead-time, and obsolete power semiconductors specifically to support engineers and buyers who cannot afford to wait on factory production cycles.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders placed before 5PM EST.
