SKKT56-12E Semikron - Thyristor / Diode Module

SKKT56-12E Description

SKKT56-12E is a 1200 V, 55 A thyristor module made by Semikron. Common uses are AC switches, soft starters, DC drives and controlled rectifiers in industrial power 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.

USComponent has sourced power semiconductors for maintenance teams and OEMs since 2001. For price and availability of the SKKT56-12E, send us a request for quote. Please confirm the specifications against the manufacturer's datasheet before purchase.
