The FF400R33KF2CB3NOSA1 is a high-voltage IGBT inverter module from Infineon Technologies, rated for a collector-emitter voltage of 3300 V and a continuous DC collector current of 400 A at 80°C case temperature. It utilizes IGBT2 Fast technology with an AlSiC baseplate and AlN internal insulation. The module features a short-circuit withstand capability of 2000 A for up to 10 µs. Key electrical parameters include a typical collector-emitter saturation voltage of 3.40 V at 25°C and a forward diode voltage of 2.80 V at 25°C. Thermal resistance from junction to case is 26.0 K/kW for the IGBT and 51.0 K/kW for the diode.
Verify the specific ordering suffix B3NOSA1 against official Infineon documentation to confirm exact manufacturing lot details and compliance status. Ensure that the procurement channel provides valid traceability certificates matching the component marking. Cross-reference the datasheet revision 2.1 to confirm all technical specifications align with the delivered units before integration into production systems.
Select this module for applications requiring high blocking voltage and significant current handling capacity. Evaluate the thermal management requirements based on the specified junction-to-case thermal resistance values. Confirm that the gate drive circuitry can accommodate the recommended peak gate-emitter voltage limits and internal gate resistor characteristics to ensure optimal switching performance and device protection during operation.
This component belongs to the FFxxR series of high-power IGBT modules designed by Infineon Technologies.
