DT142N14KOF Infineon - Power Transistor Module

DT142N14KOF Description

Infineon Technologies (formerly Eupec) DT142N14KOF is a thyristor module rated at 1400 V. You'll find thyristors like this in soft starters, static switches, DC motor controllers and heater controls. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.
