8ETH03S/8ETH03-1 Vishay High Power Products Hyperfast Rectifier, 8 A FRED PtTM FEATURES • Hyperfast recovery time 8ETH03-1 8ETH03S • Low forward voltage drop • Low leakage current • 175 °C operating junction temperature • Designed and qualified for industrial level Base cathode 2 2 N/C D2PAK 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. 3 1 3 Anode 1 N/C DESCRIPTION/APPLICATIONS Anode TO-262 PRODUCT SUMMARY trr 35 ns IF(AV) 8A VR 300 V ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL TEST CONDITIONS MAX.
