STW7NC90Z N-CHANNEL 900V - 1.55? - 6A TO-247 Zener-Protected PowerMESH™III MOSFET TYPE VDSS RDS(on) ID STW7NC90Z 900 V < 1.9 ? 6 A TYPICAL RDS(on) = 1.55? EXTREMELY HIGH dv/dt CAPABILITY GATE-TO-SOURCE ZENER DIODES 100% AVALANCHE TESTED VERY LOW INTRINSIC CAPACITANCES GATE CHARGE MINIMIZED TO-247 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 request- ed by a large variety of single-switch applications.
