SKKT42-08E Semikron - Thyristor / Diode Module

SKKT42-08E Description

Semikron makes the SKKT42-08E, an 800 V, 75 A thyristor module. Typical applications include soft starters, AC power controllers, controlled rectifiers, DC motor drives and heating control. 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.
