IRF840 N-CHANNEL 500V - 0.75 - 8A TO-220 PowerMeshTMII MOSFET TYPE VDSS RDS(on) ID IRF840 500 V < 0.85 8A s TYPICAL RDS(on) = 0.75 s EXTREMELY HIGH dv/dt CAPABILITY s 100% AVALANCHE TESTED s NEW HIGH VOLTAGE BENCHMARK 3 s GATE CHARGE MINIMIZED 2 1 DESCRIPTION (s) TO-220 The PowerMESHTMII is the evolution of the first ct generation of MESH OVERLAYTM. The layout re- finements introduced greatly improve the Ron*area figure of merit while keeping the device at the lead- ing edge for what concerns switching speed, gate charge and ruggedness.
