PDF datasheet, 156 KB, covering ON Semiconductor NTMFS4943N, an N-channel power MOSFET in the SO-8FL package. It is useful when a laptop power stage shows a short or a missing rail and the switching transistor needs to be checked or replaced. The pin diagram shows where to probe, and the electrical tables give voltage, current and on-resistance for comparing substitutes. Check the marking code against the device marking section, because small differences between NTMFS variants matter in high-current converters.
