STP9NK65Z STP9NK65ZFP N-CHANNEL 650V - 1? - 7A TO-220/TO-220FP Zener-Protected SuperMESH™Power MOSFET TARGET DATA TYPE VDSS RDS(on) ID Pw STP9NK65Z 650 V < 1.2 ? 7 A 110 W STP9NK65ZFP 650 V < 1.2 ? 7 A 30 W TYPICAL RDS(on) = 1.0 ? EXTREMELY HIGH dv/dt CAPABILITY IMPROVED ESD CAPABILITY 3 3 2 100% AVALANCHE RATED 2 1 1 GATE CHARGE MINIMIZED VERY LOW INTRINSIC CAPACITANCES TO-220 TO-220FP VERY GOOD MANUFACTURING REPEATIBILITY DESCRIPTION The SuperMESH™ series is obtained through an extreme optimization of ST’s well established strip- INTERNAL SCHEMATIC DIAGRAM based PowerMESH™ layout. In addition to pushing on-resistance significantly down, special care is tak- en to ensure a very good dv/dt capability for the most demanding applications. Such series comp
