CD420860B Powerex - Thyristor

CD420860B Description

CD420860B is an 800 V, 60 A thyristor (SCR) made by Powerex. 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.

USComponent (Young & New Century LLC) supplies power modules, thyristors, diodes and other industrial components, including legacy parts. Contact us for a quote on the CD420860B, and please confirm ratings against the datasheet before ordering.
