This dual rating means the MOSFET can be driven directly from a 5 V logic-level gate driver for reduced component count, or from a standard 10 V rail to achieve the lowest possible Rds(on) for minimum conduction losses. The ±20 V maximum gate-source voltage provides headroom against overshoot on the gate drive line. ## Thermal and package considerations for the TO-220 build The through-hole mounting (TO-220-3) suits point-to-point wiring or PCB mounting with a tab soldered to a copper island.","metaTitle":"STMicroelectronics STP140N4F6 N-Channel MOSFET","metaDescription":"STP140N4F6 N-Channel MOSFET from STMicroelectronics STripFET F6 series. 40V Vdss, 80A Id, 168W Pd, TO-220 package.
