STP5NK65Z N-CHANNEL 650V - 1.5? - 5A TO-220 Zener-Protected SuperMESH™Power MOSFET TYPE VDSS RDS(on) ID Pw STP5NK65Z 650 V < 1.8 ? 5 A 85 W TYPICAL RDS(on) = 1.5 ? EXTREMELY HIGH dv/dt CAPABILITY IMPROVED ESD CAPABILITY 100% AVALANCHE RATED GATE CHARGE MINIMIZED VERY LOW INTRINSIC CAPACITANCES VERY GOOD MANUFACTURING TO-220 REPEATIBILITY DESCRIPTION The SuperMESH™ series is obtained through an extreme optimization of ST’s well established strip- based PowerMESH™ layout. In addition to pushing INTERNAL SCHEMATIC DIAGRAM on-resistance significantly down, special care is tak- en to ensure a very good dv/dt capability for the most demanding applications. Such series comple- ments ST full range of high voltage MOSFETs in- cluding revolutionary MDmesh™ products. A
