STP55NF03L STB55NF03L STB55NF03L-1 N-CHANNEL 30V - 0.01 ? - 55A TO-220/D2PAK/I2PAK STripFET™ II POWER MOSFET TYPE VDSS RDS(on) ID STP55NF03L 30 V <0.013 ? 55 A STB55NF03L 30 V <0.013 ? 55 A STB55NF03L-1 30 V <0.013 ? 55 A TYPICAL RDS(on) = 0.01 ? 3 3 1 2 OPTIMIZED FOR HIGH SWITCHING 1 OPERATIONS D2PAK I2PAK LOW GATE CHARGE TO-263 TO-262 LOGIC LEVEL GATE DRIVE 3 DESCRIPTION 2 1 This Power MOSFET is the latest development of STMicroelectronis unique "Single Feature Size™" TO-220 strip-based process. The resulting transistor shows extremely high packing density for low on- resistance, rugged avalanche characteristics and INTERNAL SCHEMATIC DIAGRAM less critical alignment steps therefore a remark- able manufacturing reproducibility. APPLICATIONS LOW VOLTAGE
