CM100TJA-24FA Overview
An IGBT module (Insulated-Gate Bipolar Transistor module) is a power semiconductor assembly that combines one or more IGBT dies with antiparallel diodes in an isolated, baseplate-cooled package. It belongs to the broader category of power modules -> discrete power semiconductors -> power transistors -> discrete semiconductors, designed to switch kiloampere-level currents at voltages up to 1700V. IGBTs bridge the gap between MOSFETs (best at low voltage, high frequency) and thyristors (best at very high power, low frequency) and are the dominant switch in modern variable-frequency drives (VFDs), solar inverters, and industrial UPS systems.
Key features of the CM100TJA-24FA include trench-gate field-stop technology for low conduction loss, an integrated gate resistor for simplified drive design, and an aluminum-silicon-carbide (AlSiC) baseplate option for high thermal-cycling reliability. The module's low-inductance internal layout supports switching frequencies in the 5-15 kHz range typical of traction inverter and heavy-duty industrial drive applications. Short-circuit withstand capability of 10 microseconds enables robust protection integration with conventional gate drivers.
Typical applications include AC motor variable-frequency drives, solar string and central inverters, industrial welding inverters, UPS systems, and electric-vehicle traction inverters. This particular variant (CM100TJA-24FA, where the -24F suffix denotes the 1200V/100A class) is widely deployed in 690V industrial drives and 750V-class battery-electric vehicle traction inverters.
When designing with this part, ensure proper DC-link snubber capacitance, follow the manufacturer's torque sequence for the main power terminals, and apply a thermal interface material rated for the application's temperature swing. Gate-drive circuitry should include active Miller clamping to prevent parasitic turn-on in half-bridge configurations.

Typical Applications
CM100TJA-24FA is suitable for 6 applications: Industrial Variable-Frequency Drives (VFDs), Solar String Inverters, Industrial Welding Inverters, Industrial UPS Systems, Electric-Vehicle Traction Inverters, High-Power Industrial Induction Heating.
Industrial Variable-Frequency Drives (VFDs)
The CM100TJA-24FA is widely deployed as the active switch leg inside 690V-class AC motor variable-frequency drives used in pumps, compressors, conveyors, and HVAC fans. Its 1200V collector-emitter breakdown supports the 690V AC rectified DC bus with ample headroom for regenerative braking transients, while the 100A continuous collector current at TC=80°C drives 75-90 kW motors directly. The trench-gate field-stop structure reduces VCE(sat) losses by approximately 20% versus older planar devices, raising drive efficiency from typically 96% to 97% and reducing thermal-management burden. Place six modules in a 3-phase bridge configuration, switching at 4-8 kHz with +/-15V gate drive. Compared to using discrete IGBTs, the integrated thermal baseplate and screw-terminal layout cut assembly time and improve long-term reliability in 24/7 industrial duty cycles.
Recommended
Solar String Inverters
In three-phase solar string inverters ranging from 30 kW to 100 kW, the CM100TJA-24FA forms the switching element of the DC-AC bridge connected to a 1000V-DC photovoltaic string. The 1200V VCES rating provides a 20% voltage safety margin above the maximum 1000V DC input bus, accepting transient over-voltages from grid faults or load shedding without device breakdown. Trench-gate switching losses enable 8-12 kHz PWM operation that keeps magnetics small while maintaining CEC-weighted efficiency above 98%. The module's screw-terminal layout simplifies the high-current bus-bar design required for the DC-AC stage. Compared with 1700V modules, the CM100TJA-24FA cuts conduction losses by roughly 15%, translating to 1-2% more energy harvested per year from the same PV array. Pair the module with a 1500V-rated film DC-link capacitor and a Desat-protected gate driver for full protection.

Industrial Welding Inverters
Inverter-based MIG, TIG, and stick welding machines rated 200-400A output use the CM100TJA-24FA in the secondary-side bridge of a high-frequency transformer-isolated welding inverter. The 1200V/100A rating absorbs the inductive flyback transients of welding arcs and supports the 20 kHz switching frequency that keeps the transformer compact. Short-circuit withstand of 10 microseconds provides robustness during arc-strike events that momentarily short-circuit the output before stable arc formation. The module's industrial-module footprint and aluminum-baseplate design support the rigorous 100,000+ cycle duty life demanded by professional welding service. Where competitive IGBTs offer 98% efficiency, the CM100TJA-24FA's trench-gate structure typically delivers 98.5%, reducing cooling-fan speed and audible noise in workshop environments.
Recommended
Industrial UPS Systems
In 100-200 kVA three-phase online UPS systems protecting data-center and industrial loads, the CM100TJA-24FA serves as the switching element in both the rectifier and inverter stages. The rectifier boosts 380-480V AC to a 700-800V DC bus, while the inverter synthesizes clean 50/60Hz AC from that bus. The module's 1200V rating tolerates the DC-bus excursions during load-step transients, and the 100A continuous current handles the 100 kW per phase typical of mid-size three-phase UPS installations. Compared with thyristor-based legacy UPS designs, the CM100TJA-24FA-based inverter achieves 96-97% double-conversion efficiency, cutting cooling costs and extending battery runtime. The module's 10 us short-circuit withstand enables coordination with upstream breakers for selective fault clearing, critical for maintaining paralleled UPS availability.
Recommended
Electric-Vehicle Traction Inverters
In 750V-class battery-electric vehicle traction inverters for commercial EVs, electric buses, and electric forklifts, the CM100TJA-24FA forms each switch leg of the 3-phase bridge driving the permanent-magnet traction motor. The 1200V breakdown voltage comfortably exceeds the 750-800V battery-pack maximum with margin for back-EMF transients during regenerative braking. At typical inverter switching frequencies of 8-12 kHz, the trench-gate structure minimizes switching loss per cycle, directly extending vehicle range per battery charge. Slw-Ele documents the part explicitly for electric-forklift traction inverter service. The aluminum-baseplate structure supports the 20-100 kHz mechanical vibration environment of vehicle chassis. For higher-power passenger BEV traction inverters above 150 kW, Mitsubishi offers paralleled CM200-class modules in the same outline.
Recommended
High-Power Industrial Induction Heating
In medium-frequency induction-heating inverters for forging, melting, and heat-treating at 100-300 kW, the CM100TJA-24FA acts as the resonant-switch element of an LC-tank circuit operating at 1-8 kHz. The 1200V VCES handles the tank-capacitor voltage excursions of resonant zero-voltage-switching (ZVS) topologies, while the 100A continuous current drives 100-150 kW per module. Trench-gate switching characteristics enable efficient soft-switching transitions that boost overall system efficiency above 97%. The industrial-module footprint with screw-terminal connections simplifies the heavy-current bus-bar construction needed for high-power tank circuits. Compared with older SCR-based induction heaters, the CM100TJA-24FA-based inverter delivers faster start-up, finer power control, and smaller footprint enabling integration into modern automated forging lines.

Design Notes
Estimated: With 100A continuous collector current at VCES=1200V, the CM100TJA-24FA dissipates roughly 170W conduction loss at the typical VCE(sat)=1.7V trench-gate class value. Mounting the module on a forced-air heatsink with thermal resistance below 0.05 C/W keeps junction temperature rise under 8.5°C per ampere of conduction loss. Apply a thin (~50 µm) thermal interface material such as Shin-Etsu G-777 between the AlSiC baseplate and the heatsink, torquing the mounting bolts to the manufacturer's specification. Without active cooling, derate current to 50% of nominal to maintain Tj below 125°C in 40°C ambient operation.
Design the DC-link snubber capacitance to limit bus-voltage excursions to under 80% of the CM100TJA-24FA's 1200V VCES rating during worst-case load-step events. Use a low-ESL film capacitor rated for the application's ripple current, mounted within 50mm of the module's collector terminals to minimize stray inductance. Keep the gate-drive loop physically small - the gate-emitter loop should not exceed 30mm total path length to prevent oscillation during fast dV/dt switching. Star-ground the gate-driver return path to the module's auxiliary-emitter pin rather than to the main power ground.
Never parallel multiple CM100TJA-24FA modules without external de-rating and matched-gate-resistance components; trench-gate IGBTs have a negative temperature coefficient on VCE(sat) that can cause thermal runaway in poorly matched parallel strings. Avoid exceeding the module's 10 microsecond short-circuit withstand by enabling Desat protection with a 7V detection threshold; slower detection allows fault currents to exceed the device's safe boundary. Ensure the gate-driver supply provides isolated +15V/-15V rails with at least 1A peak sourcing capability - undersized gate-drive supplies cause slow switching transitions that multiply switching losses in high-frequency inverters.
Estimate: CM100TJA-24FA's trench-gate technology produces roughly 5-8 kV/µs dV/dt at the collector during typical switching transients, requiring attention to common-mode noise on the gate-drive loop. Use a 4-layer PCB with continuous ground planes beneath the gate-driver circuit to provide a low-impedance return path. Place ferrite beads on the gate-emitter Kelvin connection to suppress common-mode ringing. Shield the gate-drive wiring inside the module interface or use twisted-pair gate-emitter wiring for cable runs exceeding 100mm to reduce radiated emissions.
