1DI480A-055 Fuji Electric - Bipolar Transistor Module

1DI480A-055 Description

The Fuji Electric 1DI480A-055 is a Darlington transistor module, rated for 600 V and 480 A. Inside, it has a single switch with its freewheeling diode (1-in-1). It was a workhorse in drives and power supplies before IGBTs took over, and it is still needed to repair that equipment.
