In a typical layout, the tab is soldered to a copper pad on the PCB — that pad area sets the junction-to-ambient thermal resistance. For the 80 W dissipation rating at case temperature, a proper thermal pad with vias to an inner-layer copper plane is expected. ## Temperature range and compliance The part is ROHS3 compliant.","metaTitle":"STD4NK80ZT4 N-Ch MOSFET, 800V 3A DPAK, Active","metaDescription":"STD4NK80ZT4 N-channel MOSFET, 800V Vdss, 3A continuous drain, 3.5 Ohm Rds(on) at 10V, DPAK surface mount.
