The STF6N52K3 is listed as obsolete. Buyers should evaluate functionally similar SuperMESH3 devices from STMicroelectronics with comparable 525 V and 5 A ratings in the same TO-220FP package. ## Thermal and mounting — TO-220FP full-pack advantage The TO-220FP full-pack package isolates the tab from the drain potential, so no mica washer or insulating pad is needed when mounting to a grounded heatsink. The through-hole mounting suits point-to-point wiring and board-level repairs.","metaTitle":"STF6N52K3 N-Channel MOSFET, 525 V, 5 A, TO-220FP, Obsolete","metaDescription":"STF6N52K3 SuperMESH3 N-channel MOSFET, 525 Vdss, 5 A Id, 1.2 Ohm Rds(on) at 10 V.
