Vishay VSKT142 12PBF SCR Module

The Vishay VSKT142/12PBF SCR module is a high-power thyristor module designed for controlled rectification, power regulation, and motor control in industrial electrical systems. This dual SCR module features an electrically isolated baseplate and heatsink-mount construction, enabling reliable high-current switching in demanding environments. With a repetitive peak off-state voltage of 1200 V and an average forward current of 140 A, it supports both AC and DC power-control applications such as DC drives, soft starters, welding equipment, battery charging systems, and power-conversion units. Its rugged industrial-grade silicon-controlled rectifier design is well-suited for motor-control systems, induction heating equipment, renewable-energy installations, and process-control machinery requiring precise power delivery. The VSKT142/12PBF is RoHS compliant (PBF designation) and is commonly used for replacement or retrofit projects in industrial power-control systems, with common replacements including Vishay VSKT162/12PBF, Semikron SKKT142/12E, and Infineon TT142N12KOF.
