650 V, 70 A three-phase inverter module — the EconoPACK™ 2 floor
The Infineon FS50R07N2E4_B11 is a 650 V, 70 A IGBT module in the EconoPACK™ 2 series, configured as a three-phase inverter with six Trench Field Stop IGBTs and anti-parallel diodes in a single module. The module is rated for a maximum power dissipation of 190 W and includes an integrated NTC thermistor for direct junction-temperature monitoring — no external sensor needed. Junction temperature range covers -40°C to 150°C, suiting industrial motor drives, servo drives, and grid-tied inverters where the module is chassis-mounted and the baseplate is cooled via a heatsink or cold plate.
At the rated operating point of 50 A collector current with a 15 V gate drive, the typical Vce(on) is 1.95 V — this sets the conduction loss floor at 97.5 W per IGBT at that current, which drives the thermal resistance budget to the heatsink. The input capacitance (Cies) is 3.1 nF at 25 V collector-emitter, which gives the gate-driver designer a load for sizing the peak gate current and the drive power — a standard 15 V gate driver with a few amps peak can handle the switching without excessive cross-conduction. Collector-emitter breakdown is rated at 650 V, so the module can safely operate on a 400 VDC bus (typical for three-phase 230 VAC input drives) with margin for switching overshoot.
Active production, ROHS3, and NTC integration
The NTC thermistor is wired to auxiliary pins on the module — the resistance-vs-temperature curve is published in the datasheet and lets the control board read junction temperature without a separate sensor.
