Fuji Electric 7MBI75SA-120B-50 Power Supply Module

Fuji Electric 7MBI75SA-120B-50 Power Supply Module is an Intelligent Power Module (IPM) designed for high-power switching in motor drives and inverter systems. It provides 75 A collector current and 1200 V collector-emitter voltage in a 3-phase inverter bridge configuration with logic-level control signals, built for industrial environments. The module includes protection for overcurrent, overtemperature, and undervoltage conditions and operates from -40°C to +150°C (junction); it mounts via screws and requires a heatsink for cooling, with an insulation voltage rated at approximately 2500 V AC. Widely used in industrial inverters, servo drives, UPS systems, and automation equipment to control motor drives and energy conversion equipment, it supports reliable high-power switching performance in manufacturing plants and HVAC systems. Common replacements include Fuji 7MBI75SA-120, Mitsubishi PM75RLA120, and Infineon FS75R12KE3, reflecting cross-compatibility within industrial power-electronics fleets.
