Ultrafast recovery rectifiers

7 August 2013 Power Electronics / Power Management

Vishay has introduced 10 solderable FRED Pt Hyperfast and Ultrafast recovery rectifiers that include the industry’s first 3 A devices in the SMA package, 3 A and 4 A devices in the SMB package, and 4 A and 5 A devices in the SMC package.

Combining extremely fast and soft recovery characteristics with low forward voltage drop and low leakage current, the new rectifiers reduce switching losses in consumer products, LCD TVs, power supplies and electronic ballast lighting. ‘U Speed’ Ultrafast rectifiers offer the advantage of lower forward voltage while ‘H Speed’ Hyperfast devices provide a lower reverse recovery charge.

The rectifiers are intended for power factor correction (PFC) diodes, boost diodes for discontinuous conduction mode (DCM) and critical conduction mode (CRM), and freewheeling diodes in power switching applications. They feature a planar structure and platinum doped lifetime control to guarantee high overall performance, ruggedness and reliability characteristics. The components offer an operating junction temperature to +175°C for a more robust design.
