2DI75D-050A Fuji Electric - Power Transistor Module

2DI75D-050A Description

The Fuji Electric 2DI75D-050A is a Darlington transistor module, rated for 600 V and 75 A. Inside, it has two switches in a half-bridge (2-in-1) arrangement. It was a workhorse in drives and power supplies before IGBTs took over, and it is still needed to repair that equipment.
