FS100R12KT4G Présentation
An IGBT (Insulated Gate Bipolar Transistor) module combines multiple IGBT dies and anti-parallel diodes on a common isolated substrate inside a single molded housing. In the power-conversion hierarchy, the IGBT module sits above discrete transistors and below complete power assemblies, forming the switching stage of motor drives, solar inverters, and UPS systems. A sixpack topology contains six switches, one per branch, which is the standard configuration for three-phase DC-to-AC inversion.
Key features include the 1200 V collector-emitter blocking voltage suited to 400 V/690 V-class industrial DC links, a 100 A nominal DC collector current, and a power dissipation rating of 515 W per the DigiKey listing. The trench/field-stop IGBT4 generation delivers reduced saturation voltage and switching losses versus the earlier IGBT3 generation, while the EmCon4 Emitter Controlled diode minimizes reverse-recovery charge, lowering turn-on loss spikes in hard-switched bridges.
The module integrates an NTC thermistor for real-time junction-temperature monitoring, enabling overtemperature protection and derating strategies in the inverter controller. Solder-pin connection technology defines the base FS100R12KT4G version, while the FS100R12KT4G_B11 variant uses Infineon PressFIT press-in contacts for solder-free, replaceable assembly. Infineon qualifies the part for industrial applications according to relevant tests of IEC 60747, 60749 and 60068.
Typical applications are three-phase motor drives for industrial automation, solar and wind power converters, servo amplifiers, and uninterruptible power supplies, where a compact, isolated six-switch stage with thermal feedback is required.
A key design consideration is thermal management: with 515 W maximum dissipation, the module demands a liquid-cooled or generously sized air-cooled heatsink, correct thermal-interface material application, and NTC-based derating to keep junction temperature within limits.

Applications typiques
FS100R12KT4G convient pour 6 applications: Industrial Three-Phase Motor Drives, Solar String Inverters, Uninterruptible Power Supplies (UPS), Servo Drives and Robotics, Wind Power Converters, Welding and Induction Heating Power Supplies.
Industrial Three-Phase Motor Drives
The FS100R12KT4G is a natural fit for general-purpose variable-frequency drives (VFDs) in the 30-55 kW class running from 400/480 V AC mains with a 540-680 V DC link. Its 1200 V blocking rating provides the necessary margin over DC-link overvoltage events, while the 100 A nominal current supports continuous motor currents with short overload capability. The TRENCHSTOP IGBT4 trench/field-stop silicon reduces both VCE(sat) and turn-off energy compared to IGBT3, improving inverter efficiency at typical 4-16 kHz PWM carrier frequencies. The integrated NTC allows the drive controller to derate output current as heatsink temperature rises, protecting the module in hot enclosures. Mounted on a forced-air heatsink with proper thermal interface material, the module covers the full six-switch bridge in one isolated EconoPACK 3 footprint, shortening busbar runs and reducing stray inductance.

Solar String Inverters
In three-phase solar string inverters, the FS100R12KT4G forms the DC-to-AC output bridge fed from a boost stage holding the DC link near 600-800 V. The 1200 V class rating withstands DC-link surge and grid transient conditions, while the 100 A current class supports 30-50 kW power stages. The EmCon4 Emitter Controlled diodes exhibit low reverse-recovery charge, which directly reduces turn-on losses and EMI ringing at every PWM edge - a critical benefit at the 99%+ efficiency targets of modern inverters. The NTC output feeds the inverter MPPT/derating controller so that thermal limits are respected during peak irradiance. Because the sixpack integrates all six switches with isolation in one chassis-mount package, inverter designers save assembly area and simplify creepage/clearance compliance for IEC industrial qualification.

Uninterruptible Power Supplies (UPS)
Online double-conversion UPS systems in the 20-80 kVA range use a sixpack module like the FS100R12KT4G in both the rectifier/PFC stage and the output inverter stage. The module's 1200 V rating tolerates the 700-800 V DC bus typical of three-phase 400 V UPS designs, and 100 A class current covers continuous load current with headroom for short-circuit and battery-transfer transients. Trench/field-stop IGBT4 silicon limits conduction and switching losses during continuous double conversion, improving overall UPS efficiency. The NTC thermistor supports fan-speed control and overload protection in confined UPS cabinets. The solder-pin version suits the laminated busbar and PCB hybrid assemblies common in UPS power stages, while qualified industrial testing per IEC 60747/60749/60068 gives reliability assurance for critical backup power applications.

Servo Drives and Robotics
AC servo amplifiers driving 400 V-class permanent-magnet motors benefit directly from the FS100R12KT4G's low-loss switching and integrated thermal feedback. At PWM carrier frequencies of 8-16 kHz used for low acoustic noise and smooth torque, switching losses dominate; the TRENCHSTOP IGBT4 generation's reduced turn-off energy keeps module temperature manageable at the 10-30 A continuous phase currents typical of mid-size servos, well within the 100 A module rating and leaving strong peak-current margin for dynamic acceleration. The NTC enables real-time thermal monitoring for torque limiting in robotic joints and CNC axes. The compact EconoPACK 3 chassis-mount package lets drive designers pack the full three-phase bridge, gate drivers and current sensing onto a single compact power PCB inside the servo amplifier housing.

Wind Power Converters
Small and medium wind turbine converters (10-50 kW class) use the FS100R12KT4G in the generator-side or grid-side three-phase bridge. Wind applications demand rugged modules that survive wide thermal cycling; the EconoPACK 3's proven bond-wire and substrate construction, qualified against IEC 60747, 60749 and 60068 test suites, addresses this reliability requirement. The 1200 V class suits DC links of 600-800 V, and the 100 A rating plus EmCon4 diode robustness handle the erratic, gust-driven current profiles characteristic of wind input. The integrated NTC supports nacelle controller derating algorithms during low-wind thermal steady states and storm transients. Designers should verify lifetime cycling against Infineon's application note AN2015-01 and its loss/thermal calculator to model real wind duty cycles before prototyping.

Welding and Induction Heating Power Supplies
High-frequency welding inverters and induction heating sources use sixpack modules in bridge configurations where switching loss and diode recovery dominate thermal budget. The FS100R12KT4G's EmCon4 diodes, with their low reverse-recovery charge, mitigate the turn-on current spikes seen in hard-switched H-bridge and resonant topologies, while trench/field-stop IGBT4 silicon tolerates the short-circuit and hard-switching events inherent to metal fabrication environments. The 1200 V rating gives headroom on 540-650 V rectified three-phase inputs, and the 100 A class supports the high intermittent current pulses of welding duty cycles. The NTC enables fast thermal foldback in machines with sealed, dust-laden enclosures where fan filters degrade over time. The chassis-mount EconoPACK 3 package simplifies mounting directly onto the machine's finned aluminum heat spreader.

- Integrated NTC thermal feedback (vs FS100R12KS4)
Notes de conception
With up to 515 W of dissipation, heatsink selection dominates reliability. Estimated: at 300 W average loss and a target 50 C junction-to-ambient rise, total thermal resistance (junction-to-case + interface + heatsink) must be below about 0.17 C/W, which typically requires forced air or liquid cooling; a natural-convection extrusion will not suffice. Use a thin, evenly applied thermal grease layer and tighten the mounting screws to the datasheet torque in the specified sequence. Use the NTC (with the datasheet R-T curve) to derate output current above ~80 C heatsink temperature.
Minimize stray inductance in the DC-link loop between the DC+ and DC- terminals and the link capacitors: use laminated busbars or wide PCB copper directly over the module terminals, and place snubber/film capacitors within a few centimeters of the terminals. High commutation-loop inductance causes VCE overshoot at turn-off that can approach the 1200 V rating during short-circuit or overload turn-off events. Keep gate-driver traces short and twisted-pair or differential to each module gate/emitter pin to prevent parasitic turn-on.
Do not substitute cross-brand 'equivalents' (e.g., Mitsubishi CM100DY-24A, Fuji 2MBI100S-120, Semikron SKM100GB12T4 listed by some distributors) onto an EconoPACK 3 footprint - they are dual modules, not sixpacks, and will not fit. Confirm lifecycle status before new designs: community reports mark the FS100R12KT4G as NRND, so new PCBs should verify active-status alternatives with Infineon. Finally, drive the NTC through proper isolation/filtering - it is referenced to module power potential, not system ground.
