Silicon Power Electronics introduces an economical range of bridge rectifiers using high-quality glass passivated diode/thyristor chips with high voltage and high surge current rating. Features include electrically insulated package and excellent thermal conductivity ensuring life of the product. Typical applications include Invertors, UPS, Welding machines, and Alternator.


Stud mounted diffused junction Silicon rectifiers are specially designed for rotating applications.
Diodes are spin tested at 3600rpm and pull tested to ensure quality for rotar application
