STS5DNF20V N-CHANNEL 20V - 0.030 ? - 5A SO-8 2.7V-DRIVE STripFET™ II POWER MOSFET TYPE VDSS RDS(on) ID < 0.040 ? ( @ 4.5 V ) STS5DNF20V 20 V 5 A < 0.045 ? ( @ 2.7 V ) TYPICAL RDS(on) = 0.030 ? @ 4.5 V TYPICAL RDS(on) = 0.037 ? @ 2.7 V ULTRA LOW THRESHOLD GATE DRIVE (2.7 V) STANDARD OUTLINE FOR EASY AUTOMATED SURFACE MOUNT ASSEMBLY SO-8 DESCRIPTION This Power MOSFET is the latest development of STMicroelectronis unique "Single Feature Size™" strip-based process. The resulting transistor shows extremely high packing density for low on- INTERNAL SCHEMATIC DIAGRAM resistance, rugged avalanche characteristics and less critical alignment steps therefore a remark- able manufacturing reproducibility.
