STP5NB40 STP5NB40FP N-CHANNEL 400V - 1.47? - 4.7A TO-220/TO-220FP PowerMesh™ MOSFET TYPE VDSS RDS(on) ID STP5NB40 400 V < 1.8 ? 4.7 A STP5NB40FP 400 V < 1.8 ? 4.7 A TYPICAL RDS(on) = 1.47 ? EXTREMELY HIGH dv/dt CAPABILITY 100% AVALANCHE TESTED 3 3 VERY LOW INTRINSIC CAPACITANCES 2 2 1 1 GATE CHARGE MINIMIZED TO-220 TO-220FP DESCRIPTION Using the latest high voltage MESH OVERLAY™ process, STMicroelectronics has designed an ad- vanced family of power MOSFETs with outstanding performances. The new patent pending strip layout coupled with the Company’s proprieraty edge termi- INTERNAL SCHEMATIC DIAGRAM nation structure, gives the lowest RDS(on) per area, exceptional avalanche and dv/dt capabilities and unrivalled gate charge and switching characteris- tics.
