A cross-reference search against similar Vdss and Rds(on) ratings is the practical path for a new production allocation. ## 1.5 Ohm Rds(on) — what the on-resistance number means for your design The 10 V drive voltage is the recommended gate drive to achieve the lowest on-resistance; driving the gate with a lower voltage, say 5 V, will increase Rds(on) significantly — the gate threshold voltage can be as high as 4.5 V at 50 µA, so margin at low gate drive is thin. ## TO-220FP full-pack — mounting and isolation The TO-220FP (TO-220-3 Full Pack) is a through-hole package with a fully molded, electrically isolated backside tab. Unlike a standard TO-220 where the metal tab is connected to the drain, the full-pack version lets you bolt the device directly to a grounded heatsink without an insulating washer. This simplifies assembly and reduces thermal resistance from junction to case. The three leads are formed for through-hole soldering on a standard 2.54 mm pitch. No special footprint beyond the usual TO-220 layout is needed.","metaTitle":"STF5NK52ZD SuperMESH N-Channel MOSFET, 520 V, 1.5 Ohm","metaDescription":"STF5NK52ZD N-channel 520 V MOSFET in TO-220FP full-pack, 1.5 Ohm Rds(on) at 2.2 A.
