8ETU04 Vishay High Power Products Ultrafast Rectifier, 8 A FRED PtTM FEATURES • Ultrafast recovery time Base cathode • Low forward voltage drop • Low leakage current 2 • 175 °C operating junction temperature • Designed and qualified for industrial level DESCRIPTION/APPLICATIONS 1 Cathode TO-220AC FRED PtTM series are the state of the art ultrafast recovery rectifiers specifically designed with optimized performance of forward voltage drop and ultrafast 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 diode 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 Anode PRODUCT SUMMARY trr 60 ns IF(AV) 8A VR 400 V ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL TEST CONDITIONS VALUES UNITS 400 V Repetitive peak reverse voltage VRRM Average rectified forward current IF(AV) TC = 155 °C 8 Non-repetitive peak surge current IFSM TC = 25 °C 100 Repetitive peak forward current Operating junction and storage temperatures A IFRM 16 TJ, TStg - 65 to 175 °C ELECTRICAL SPECIFICATIONS (TJ = 25 °C unless otherwise specified) PARAMETER Breakdown voltage, blocking voltage Forward voltage SYMBOL VBR, VR VF TEST CONDITIONS MIN.
