Fuji Electric — 1MBI300S-120 IGBT Power Module 1200 V • 300 A • Single IGBT (1-Pack) • Integrated Freewheel Diode • Isolated Baseplate
What it is

The Fuji Electric 1MBI300S-120 is a high-power 1200 V, 300 A single IGBT module designed for industrial switching and power-conversion applications. The module combines a high-current IGBT with an integrated antiparallel freewheel diode in a rugged, electrically isolated package designed for direct heatsink mounting.

The 1MBI300S-120 is suited to UPS inverter and converter stages, industrial motor drives, DC-link choppers, welding equipment and other high-power switching systems. Its single-switch configuration makes it especially useful for servicing legacy equipment originally designed around discrete high-current IGBT modules.
