STW20NM50 N-CHANNEL 500V - 0.20? - 20A TO-247 MDmesh™Power MOSFET TYPE VDSS RDS(on) ID STW20NM50 500V < 0.25? 20 A TYPICAL RDS(on) = 0.20? HIGH dv/dt AND AVALANCHE CAPABILITIES 100% AVALANCHE TESTED LOW INPUT CAPACITANCE AND GATE CHARGE 3 2 LOW GATE INPUT RESISTANCE 1 TIGHT PROCESS CONTROL AND HIGH TO-247 MANUFACTURING YIELDS DESCRIPTION The MDmesh™ is a new revolutionary MOSFET technology that associates the Multiple Drain pro- cess with the Company’s PowerMESH™ horizontal INTERNAL SCHEMATIC DIAGRAM layout. The resulting product has an outstanding low on-resistance, impressively high dv/dt and excellent avalanche characteristics. The adoption of the Company’s proprietary strip technique yields overall dynamic performance that is significantly better than
