Datasheet for the SI4483AD, a Vishay P-channel power MOSFET, in a 161 KB PDF. Laptop and motherboard technicians meet this kind of part in load switches and power path circuits, such as adapter or battery input selection. The document gives pinout, package outline, on-resistance, gate threshold and maximum voltage and current ratings. Use it to identify pins when testing for shorts, to confirm a suspected failed part, or to pick a substitute with comparable voltage rating, RDS(on) and package.
