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