STMicroelectronics lists the STF40NF06 as Obsolete. The -55°C to 175°C junction range means this part was specified into military-temperature applications; if a drop-in replacement is needed, a parametric search on 60 V Vdss, 23 A Id, and TO-220FP package is the starting point, but no pin-compatible alternate is documented. With a 32 nC total gate charge at 10 V and 920 pF input capacitance at 25 V drain bias, the STF40NF06 is a medium-speed switch. The 4 V gate threshold at 250 µA gives a comfortable margin for 5 V logic-driven gate drivers, but the 10 V drive voltage for minimum Rds(on) means a bootstrap or dedicated gate-drive rail is needed to hit the 28 mOhm figure. The ±20 V Vgs max leaves headroom for gate ringing in hard-switched topologies.","metaTitle":"STF40NF06 N-Channel MOSFET, 60 V, 23 A, TO-220FP","metaDescription":"STripFET II N-channel MOSFET, 60 V Vdss, 23 A Id, 28 mOhm Rds(on) at 10 V.
