20CTH03PbF/20CTH03FPPbF Vishay High Power Products Hyperfast Rectifier, 2 x 10 A FRED PtTM FEATURES 20CTH03PbF 20CTH03FPPbF • Hyperfast recovery time Pb-free • Low forward voltage drop Available • Low leakage current RoHS* • 175 °C operating junction temperature COMPLIANT • Fully isolated package (VINS = 2500 VRMS) Base common cathode 2 • Lead (Pb)-free (“PbF” suffix) • TO-220 designed and qualified for AEC Q101 level • TO-220FP designed and qualified for industrial level 2 Common cathode 1 Anode 2 Common cathode 3 Anode TO-220AB DESCRIPTION/APPLICATIONS 3 Anode 1 Anode 300 V series are the state of the art hyperfast recovery rectifiers designed with optimized performance of forward voltage drop and hyperfast recovery time. The planar structure and the platinum doped life time control, guarantee the best overall performance, ruggedness and reliability characteristics. These devices are intended for use in the output rectification stage of SMPS, UPS, dc-to-dc converters as well as freewheeling diodes in low voltage inverters and chopper motor drives. Their extremely optimized stored charge and low recovery current minimize the switching losses and reduce over dissipation in the switching element and snubbers.
