STP2NC70Z, STP2NC70ZFP STD1NC70Z, STD1NC70Z-1 N-CHANNEL 700V - 7.3? - 1.4A TO-220/FP/DPAK/IPAK Zener-Protected PowerMESH™III MOSFET TYPE VDSS RDS(on) ID Pw STP2NC70Z 700 V < 8.5 ? 1.4 A 50 W STP2NC70ZFP 700 V < 8.5 ? 1.4 A 25 W STD1NC70Z 700 V < 8.5 ? 1.4 A 45 W 3 STD1NC70Z-1 700 V < 8.5 ? 1.4 A 45 W 2 1 TYPICAL RDS(on) = 7.3 ? TO-220 TO-220FP EXTREMELY HIGH dv/dt CAPABILITY 100% AVALANCHE TESTED GATE CHARGE MINIMIZED VERY LOW INTRINSIC CAPACITANCES 3 3 2 1 1 IPAK DPAK DESCRIPTION The third generation of MESH OVERLAY™ Power MOSFETs for very high voltage exhibits unsur- passed on-resistance per unit area while integrating back-to-back Zener diodes between gate and source. Such arrangement gives extra ESD capabil- ity with higher ruggedness performance as re
