DD81S1400K-K Infineon - Power Transistor Module

DD81S1400K-K Description

Rated at 1400 V and 81 A, the Infineon Technologies (formerly Eupec) DD81S1400K-K is a diode module. Typical applications include AC-to-DC rectification in drives and power supplies, freewheeling paths and battery charging. 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.
