STB3NC90Z N-CHANNEL 900V - 3.2? - 3.5A D2PAK Zener-Protected PowerMESH™III MOSFET TYPE VDSS RDS(on) ID STB3NC90 900V < 3.5? 3.5 A TYPICAL RDS(on) = 3.2? EXTREMELY HIGH dv/dt AND CAPABILITY GATE TO - SOURCE ZENER DIODES 3 100% AVALANCHE TESTED 1 VERY LOW GATE INPUT RESISTANCE GATE CHARGE MINIMIZED D2PAK DESCRIPTION The third generation of MESH OVERLAY™ Power MOSFETs for very high voltage exhibits unsurpassed on-resistance per unit area while integrating back-to- back Zener diodes between gate and source. Such ar- rangement gives extra ESD capability with higher rug- gedness performance as requested by a large variety of single-switch applications.
