Vishay Launches New FRED Pt Fifth Generation Hyperfast and Ultrafast Recovery Rectifiers

     Vishay Intertechnology announced the launch of 15 new FRED Pt 5th generation 600 V and 1200 V Hyperfast and Ultrafast recovery rectifiers using SOT-227 small package. The conduction and switching losses of Vishay Semiconductors rectifier have reached an advanced level among similar devices, improving the efficiency of high-frequency inverter and soft switching or resonant circuit.

     Recently released devices can be used with MOSFET or high-speed IGBT, and are applicable to PFC, electric (EV)/hybrid electric vehicle (HEV) battery charging station output rectifier stage, solar inverter boost stage and UPS. In these applications, the conduction loss of the rectifier is lower than that of the previous generation devices, and the reverse recovery loss is low. In addition, the semiconductor devices packaged by SOT-227 are insulated from the copper substrate, making it easy to build a universal radiator and small assembly.

     30A/600V devices adopt single-phase bridge configuration, and 60A - 300A/600V - 1200V devices adopt double diode configuration. The rectifier has two speed types, namely, X-type Hyperfast and H-type Ultrafast. H-type rectifier has the advantage of low conduction loss, while X-type rectifier has the advantage of fast recovery. The operating temperature of the device reaches+175 ° C.
