SKKT72-16E Semikron - Thyristor / Diode Module

SKKT72-16E Description

Semikron makes the SKKT72-16E, a 1600 V, 125 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.
