SKKD700-08 Semikron - Power Transistor Module

SKKD700-08 Description

SKKD700-08 is a 800 V, 47 A diode module made by Semikron. It is used in input rectifiers, freewheeling and clamping circuits, battery chargers and welding power sources. 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 (Young & New Century LLC) supplies power modules, thyristors, diodes and other industrial components, including legacy parts. Contact us for a quote on the SKKD700-08, and please confirm ratings against the datasheet before ordering.
