The Mitsubishi CM75RL-24NF is a 75A, 1200V IGBT module from Mitsubishi's RL-series platform, engineered for demanding switching applications where efficiency, thermal performance, and reliability are non-negotiable. This module features a standard dual or six-pack topology suited for high-frequency PWM operation, low V_CE(sat) characteristics, and a co-packaged fast-recovery freewheeling diode. Its isolated base plate simplifies heatsink mounting and supports high power density system designs operating across wide thermal ranges in industrial environments.

The CM75RL-24NF is widely deployed in AC variable frequency drives (VFDs), servo amplifiers, UPS systems, induction heating equipment, and industrial welding inverters. Its 1200V blocking voltage and 75A continuous collector current rating make it a strong fit for three-phase motor control stages in the 15–37kW range. OEM machine builders, elevator drive manufacturers, and process automation integrators commonly specify this module when designing or repairing drives that must meet IEC and UL performance standards under continuous industrial duty cycles.

Key Features of the CM75RL-24NF:

• 1200V V_CES collector-emitter blocking voltage with 75A rated continuous collector current for mid-range industrial drive applications
• Low V_CE(sat) minimizes conduction losses during high-duty-cycle PWM switching, reducing thermal stress on the module and heatsink assembly
• Integrated co-packaged fast-recovery freewheeling diodes with matched reverse recovery characteristics for clean commutation at elevated switching frequencies
• Isolated copper base plate construction provides electrical isolation from heatsink while ensuring low thermal resistance (R_th(c-s)) for efficient heat transfer
• Optimized gate charge and switching times compatible with standard IGBT gate driver ICs operating at 15V / -8V bipolar supply rails
• Short-circuit withstand capability (t_SC) supports protective gate drive designs in fault-tolerant inverter and converter topologies

With a current factory lead time of 44 weeks for new production, procurement teams relying solely on the manufacturer's supply chain face significant exposure — especially in MRO, field repair, and production line downtime scenarios. The CM75RL-24NF is an active part, but long lead times in the power semiconductor market remain a persistent challenge across the industry. ATI maintains inventory of hard-to-find and long-lead-time IGBTs precisely for these situations, providing engineers and buyers a reliable source without the multi-quarter wait.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts.
