Infineon FS100R12KE3-B3 Industrial Power Supply Module

The Infineon FS100R12KE3-B3 is a 1200 V, 100 A dual IGBT power module (EconoPACK) with integrated freewheeling diodes, designed for industrial power electronics where compact, reliable high-power switching is required. It mounts on a baseplate for heat sink integration and requires an external heat sink for cooling, making it well-suited for inverter and motor-drive systems. Commonly installed in variable frequency drives, servo drive systems, power conversion units, and industrial control cabinets, it supports industrial automation drives, AC motor control, UPS systems, renewable energy inverters, welding equipment, and other high-power conversion assemblies; common replacements include Infineon FS100R12KE3, Infineon FF100R12KE3, and Fuji 2MBI100U4H-120.
