Ultrafast Rectifier, x 3 A FRED Pt 3 TO-47 long lead 3-pins PRODUCT SUMMARY Anode Base common cathode Common cathode Package TO-47 long lead 3-pins I F(AV) x 3 A V R 6 V V F at I F.75 V t rr typ. 6 ns T J max. 75 C Diode variation Common cathode 3 Anode FEATURES Ultrafast recovery time Low forward voltage drop 75 C operating junction temperature Designed and qualified according to commercial qualification Material categorization: for definitions of compliance please see www.vishay.com/doc?999 DESCRIPTIONS/APPLICATIONS VS-CPU6... series are the state of the art ultrafast recovery rectifiers 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/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.
