FS100R12N2T7_B15 Infineon 1200V 100A Sixpack IGBT Module
The FS100R12N2T7_B15 from Infineon is a 1200V, 100A six-pack IGBT module engineered around the IGBT7 TRENCHSTOP chip generation paired with an EmCon HE freewheeling diode. Built for three-phase inverter topologies in a single, compact housing, it targets designers who need a balance of switching efficiency, thermal headroom, and mechanical simplicity in industrial drive platforms.
This page consolidates the verified electrical and mechanical data so engineering and sourcing teams can evaluate suitability without ambiguity. Reference values are aligned with the manufacturer datasheet: FS100R12N2T7_B15 datasheet.
Why Engineers Specify the FS100R12N2T7_B15
The defining advantage of this module is the integration of a complete three-phase inverter (Sixpack) in one package. By consolidating six switches and six diodes, it shortens commutation loops, simplifies busbar design, and reduces parasitic inductance compared with discrete half-bridge assemblies.
The IGBT7 silicon delivers a lower VCE(sat) at rated current and an extended maximum junction temperature of Tvj op = 175°C, providing additional thermal margin for overload events without derating the continuous current rating.
What is the primary benefit of the IGBT7 chip in this module? Lower conduction losses and a 175°C operating junction temperature for higher inverter output current density.

Target Applications
For 400 V AC industrial drives requiring a compact 1200 V inverter stage, this 100 A Sixpack is the optimal building block. The combination of voltage class and current rating maps directly onto the most common low-to-medium-power three-phase systems.
- Variable frequency drives (VFD) for pumps, fans, and conveyors
- Servo drives for CNC machinery and robotics
- Solar string inverters in the 30–55 kW range
- UPS systems and energy-storage power conversion stages
- HVAC compressor inverters and commercial chillers
Design and Integration Notes
The module includes an NTC temperature sensor referenced to the baseplate-adjacent ceramic, enabling accurate thermal protection through the gate driver or controller. Symmetrical low-inductance terminal layout supports clean DC-link snubbing and predictable switching behavior at typical PWM frequencies of 4–16 kHz.
Designers replacing earlier IGBT4-based Sixpacks with this IGBT7 generation should re-verify gate resistor selection and dv/dt at the motor terminals, since the faster switching can excite cable resonances if motor filters are absent.
Is an external freewheeling diode required? No, the module integrates EmCon HE diodes matched to the IGBT switching characteristics for full inverter operation.

Frequently Asked Questions
Q: What is the maximum allowed switching frequency for the FS100R12N2T7_B15?
The module supports typical hard-switched PWM frequencies of 4–16 kHz in motor-drive applications. The exact upper limit depends on DC-link voltage, load current, gate resistor selection, and heatsink thermal resistance. Designers should validate against the loss curves and SOA charts in the official datasheet.
Q: Does the module include a brake chopper or input rectifier?
No. The FS100R12N2T7_B15 is a pure Sixpack inverter stage. For integrated rectifier and brake-chopper functions in one housing, a PIM-class device such as the FP75R12KT4_B16 is the corresponding topology.
Q: How should the integrated NTC be used?
The NTC is electrically isolated from the power circuit and is intended for monitoring module temperature. It is not a substitute for direct junction-temperature estimation, which still requires loss-model-based thermal calculation.
