STL6NK55Z N-CHANNEL 550V - 1.2? - 5.2A PowerFLAT™ Zener-Protected SuperMESH™Power MOSFET TYPE VDSS RDS(on) ID (1) Pw (1) STL6NK55Z 550 V < 1.4 ? 5.2 A 75 W TYPICAL RDS(on) = 1.2 ? EXTREMELY HIGH dv/dt CAPABILITY IMPROVED ESD CAPABILITY 100% AVALANCHE RATED GATE CHARGE MINIMIZED VERY LOW INTRINSIC CAPACITANCES VERY GOOD MANUFACTURING PowerFLAT™(5x5) REPEATIBILITY (Chip Scale Package) 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
