The 6MBP100BJ060 is part of Fuji Electric's established 6MBP series — a family of six-pack IGBT Intelligent Power Modules that integrate a complete three-phase inverter bridge into a single package. The "6M" identifies the six-transistor configuration: two IGBTs per phase (upper and lower) across all three phases — upper and lower bridge arms for U, V, and W in one module.
At 100A and 600V, the 6MBP100BJ060 drives three-phase induction and synchronous motors in the 11–22kW class from standard 380–480V AC supplies — the power level that covers the majority of general industrial motor drive applications.

Building a three-phase inverter from three separate half-bridge modules (or six individual IGBTs) requires individual heatsink mounting, multiple thermal interface preparations, and careful PCB layout to minimise parasitic inductance between modules. The 6MBP100BJ060's six-pack format addresses each of these:
Single mounting footprint: All six IGBTs are mounted in a single housing on a single heatsink contact surface — one mounting operation, one thermal interface application, one module replacement in maintenance.
Minimised commutation loop inductance: The 6-pack layout optimises the physical distances between upper and lower switch pairs — reducing the stray inductance in the commutation loop that generates voltage spikes during switching. Lower spike voltage means lower voltage stress on the IGBTs and less EMC interference from the switching transitions.
CNC machine tool spindle and servo drives: The 100A / 600V rating directly matches FANUC, Mitsubishi, and Siemens CNC drive power stage requirements for mid-range spindle and axis servo amplifiers.
Variable frequency drives (VFDs): General-purpose industrial VFDs for pump, fan, conveyor, and process motor control in the 11–22kW class from 400V supply — the most widely used power class in industrial automation.
Industrial servo drives: Servo amplifier power stages for robot joints, linear axis drives, and precision machine drives requiring fast, accurate torque control.
Uninterruptible power supplies (UPS): UPS inverter stages for industrial and commercial power backup systems — the 6-pack format simplifies the UPS inverter design.
Solar inverters: Grid-tie inverter stages for commercial and small industrial photovoltaic systems — converting DC from the solar array to grid-quality AC.
Q1: What does the "6" in 6MBP100BJ060 indicate, and how is it different from 7MBP100?
The "6" indicates a six-pack module — six IGBTs forming a complete three-phase inverter bridge (upper and lower for each of three phases). The "7MBP" series contains seven IGBTs — the same six-pack bridge plus a seventh IGBT dedicated to the dynamic braking chopper function. Use 6MBP100BJ060 in drives that handle braking externally or through a separate chopper module; use 7MBP for integrated braking applications.
Q2: What gate drive supply voltage does 6MBP100BJ060 require?
The J-series IPM gate drive circuit requires a split power supply — typically ±15V DC (positive supply for turn-on, negative supply for turn-off and active clamp). The exact supply voltage requirements are confirmed from the 6MBP100BJ060 application note or datasheet. Operating outside the specified gate supply range risks IGBT latch-up or incomplete turn-off — both potentially destructive conditions.
Q3: What fault output does 6MBP100BJ060 generate on protection activation?
When the overcurrent, short-circuit, under-voltage, or over-temperature protection activates, the module drives its fault output pin to the active state (typically low) — a signal that the host drive controller reads to initiate a controlled shutdown sequence. The protection signal must be cleared (via a reset pulse after the fault condition is resolved) before the module will resume normal operation. This fail-safe requires active acknowledgement before restart.
Q4: What minimum dead time is required in the PWM signals for 6MBP100BJ060?
Dead time — the interval between turning off one IGBT and turning on the complementary switch in the same half-bridge — prevents both upper and lower IGBTs conducting simultaneously (shoot-through). The minimum dead time for J-series Fuji IPMs is determined by the module's propagation delays and turn-off characteristics. Confirm from the 6MBP100BJ060 datasheet for the specific minimum dead time specification to use in the PWM generation circuit.
