K1270MA450

Overview

The K1270MA450 is a medium voltage silicon SCR manufactured by IXYS, designed for high-power phase control applications. It features a 4500 V repetitive peak off-state voltage and a 1270 A on-state current rating. The device utilizes a TO-200AC (K-PUK) chassis mount package to facilitate efficient thermal management in industrial settings. Key electrical characteristics include a gate trigger voltage of 3.8 V and a holding current of 16 A. Operating within a junction temperature range of -40°C to +125°C, it ensures reliable performance under demanding conditions.
