2DI50A-140 Fuji Electric - Power Transistor Module

2DI50A-140 Description

Fuji Electric makes the 2DI50A-140, a 1400 V, 50 A Darlington transistor module. 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.
