Hyperfast and Ultrafast recovery rectifiers reduce switching losses
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. These FRED Pt rectifiers offer designers a choice of current ratings, packages, and speeds to optimise efficiency in their applications; the devices increase power density to facilitate lower system costs. "U Speed" Ultrafast rectifiers offer the advantage of lower forward voltage while "H Speed" Hyperfast devices provide a lower reverse recovery charge.
The FRED Pt 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. The devices 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. The devices offer an MSL moisture level of 1 per J-STD-020, and LF maximum peak of +260 °C.
