2DI300A-050 Fuji Electric - Power Transistor Module

2DI300A-050 Description

2DI300A-050 is a 300 A Darlington transistor module made by Fuji Electric. It is built with 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.
