System Architecture & Signal Flow
The 6MBP75JA120 implements a standard three-phase, two-level voltage source inverter (VSI) topology. The six IGBT switches (Q1–Q6) are arranged in three half-bridge legs, each controlling one output phase (U, V, W). Gate signals from the PWM controller are applied to each IGBT gate via isolated gate drivers (recommended: ±15V gate drive). The integrated freewheeling diodes conduct during dead-time intervals, clamping inductive flyback voltages. DC bus voltage is applied across the P and N terminals, while AC output is taken from the U, V, W terminals to the motor load. Thermal management is achieved via a heatsink mounted to the module base plate, with thermal interface material (TIM) applied to minimize contact resistance.

Technical FAQ
Q: Is the 6MBP75JA120 a direct replacement for the 6MBP75JA060?
A: No. The 6MBP75JA060 is rated at 600V VCES, while the 6MBP75JA120 is rated at 1200V. They are not interchangeable without circuit redesign.
Q: What gate drive voltage is recommended?
A: Fuji recommends +15V / -15V gate drive for optimal switching performance and short-circuit protection margin.
Q: Can this module be used in a single-phase inverter?
A: Yes, two of the three half-bridge legs can be used for a single-phase H-bridge configuration, though the 6-in-1 package is optimized for three-phase topologies.
Q: What thermal interface material (TIM) is recommended?
A: A silicone-based TIM with thermal conductivity ≥ 1.0 W/m·K is recommended. Apply a thin, uniform layer to the base plate before mounting to the heatsink.
Q: Do you provide SPICE or simulation models?
A: Fuji Electric publishes IGBT simulation models on their official website. Contact support@konmask.com for assistance locating the correct model file.
