Vishay Semiconductors VS-E7FX0x12 FRED Pt® Hyperfast Rectifiers

Vishay Semiconductors VS-E7FX0x12 FRED Pt® Hyperfast Rectifiers are specifically designed with optimized performance of forward voltage drop and hyperfast recovery time. The planar structure and the platinum-doped lifetime control guarantee leading performance, ruggedness, and reliability characteristics. These devices are intended for use as clamp, snubber, and freewheeling diodes in flyback auxiliary power supplies, bootstrap and desaturate for HV MOSFET and IGBT drivers, and high-frequency rectifiers in a cuk and sepic circuit for LED lighting. The rectifier’s extremely optimized stored charge and low recovery current minimize the switching losses and reduce power dissipation in the switching element.
