1 Ultralow V F Hyperfast Rectifier for Discontinuous Mode PFC, 5 FRED Pt 3 2L TO-22C 2 FETURES Hyperfast recovery time Benchmark ultralow forward voltage drop 75 C operating junction temperature Low leakage current Designed and qualified according to JEDEC -JESD 47 Material categorization: for definitions of compliance please see Base cathode 2 3 Cathode node PRIMRY CHRCTERISTICS I F(V) 5 V R 6 V V F at I F.85 V t rr typ. 6 ns T J max. 75 C Package 2L TO-22C Circuit configuration Single DESCRIPTION State of the art, ultralow V F, soft-switching hyperfast rectifiers optimized for Discontinuous (Critical) Mode (DCM) Power Factor Correction (PFC). The minimized conduction loss, optimized stored charge and low recovery current minimize the switching losses and reduce over dissipation in the switching element and snubbers. The device is also intended for use as a freewheeling diode in power supplies and other power switching applications. PPLICTIONS C/DC SMPS 7 W to 4 W e.g. laptop and printer C adaptors, desktop PC, TV and monitor, games units and DVD C/DC power supplies.
