Powersem PSCH 25/08 800V 32A Rectifier Module
PSCH 25/8 Half-Controlled Rectifier Bridge
The PSCH 25/8 from Powersem is a half-controlled rectifier bridge designed for single-phase power electronics applications. It combines controlled switching via thyristors and freewheeling diodes, enabling flexible performance for industrial and commercial systems. Its design supports moderate voltage and current while maintaining efficient power conversion and consistent operation under heavy load.
Built for reliability, the PSCH 25/8 uses robust semiconductor components with well-specified off-state voltage and good thermal characteristics. The freewheeling diode ensures safe handling of inductive loads, preventing voltage spikes and improving system durability. Its package and mounting options make it suitable for environments where cooling, mechanical endurance, and long lifetime are needed.
Typical applications include AC/DC conversion in power supplies, motor control, UPS systems, and rectifier circuits in industrial equipment. For OEM and systems designers, PSCH 25/8 offers a balance of cost, performance, and ruggedness. Integration is facilitated by standard mounting styles and predictable behavior under partial load and switching stresses.
