STW9NC70Z N-CHANNEL 700V - 0.90 ? - 7.5A TO-247 Zener-Protected PowerMESH™III MOSFET TYPE VDSS RDS(on) ID STW9NC70Z 700 V < 1.2 ? 7.5A TYPICAL RDS(on) = 0.9 ? EXTREMELY HIGH dv/dt CAPABILITY GATE- TO-SOURCE ZENER DIODES 100% AVALANCHE TESTED VERY LOW INTRINSIC CAPACITANCES GATE CHARGE MINIMIZED DESCRIPTION TO-247 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 request- ed by a large variety of single-switch applications.
