STB80PF55 P-CHANNEL 55V - 0.016 ? - 80A D2PAK STripFET™ II POWER MOSFET PRELIMINARY DATA TYPE VDSS RDS(on) ID STB80PF55 55 V < 0.018 ? 80 A TYPICAL RDS(on) = 0.016 ? EXCEPTIONAL dv/dt CAPABILITY 100% AVALANCHE TESTED APPLICATION ORIENTED 3 CHARACTERIZATION 1 D2PAK DESCRIPTION TO-263 This Power MOSFET is the latest development of (Suffix “T4”) STMicroelectronis unique "Single Feature Size™" strip-based process. The resulting transistor ADD SUFFIX “T4” FOR ORDERING IN TAPE & REEL shows extremely high packing density for low on- resistance, rugged avalanche characteristics and less critical alignment steps therefore a remark- able manufacturing reproducibility.
