Equivalent & Substitute Parts Reference: SCS220KGC

Part Overview

The SCS220KGC is a silicon carbide (SiC) Schottky diode from Rohm Semiconductor, rated for 1200 V and 20A average rectified current in a TO-220AC through-hole package. The part is classified as “Obsolete,” making it necessary to source alternative or substitute models for designs requiring 1200 V, 20A SiC Schottky diodes. Identifying substitutes ensures continuity for maintenance, repair, or ongoing production where SCS220KGC is specified.
