STP10NK70Z STP10NK70ZFP N-CHANNEL 700V - 0.75? - 8.6A TO-220/TO-220FP Zener-Protected SuperMESH™Power MOSFET TYPE VDSS RDS(on) ID Pw STP10NK70Z 700 V < 0.85 ? 8.6 A 150 W STP10NK70ZFP 700 V < 0.85 ? 8.6 A 35 W TYPICAL RDS(on) = 0.75 ? EXTREMELY HIGH dv/dt CAPABILITY IMPROVED ESD CAPABILITY 3 2 100% AVALANCHE RATED 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 comple- m
