SKR71-12 Semikron - Thyristor / Diode Module

SKR71-12 Description

Semikron SKR71-12 is a rectifier diode. Diode modules like this are common in rectifier front ends, DC power supplies, welders and plating equipment. 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.
