SKKH122-16E Semikron - Power Transistor Module

SKKH122-16E Description

Rated at 1600 V and 122 A, the Semikron SKKH122-16E is a thyristor module. It is used in phase-controlled rectifiers, soft starters, battery chargers and temperature controllers for furnaces and heaters. 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.
