Vishay Siliconix SiR474DP datasheet, provided as a 322 KB PDF. The SiR-series designation indicates an N-channel power MOSFET, and the DP suffix refers to the PowerPAK SO-8 package often seen on laptop VRMs. The document lists pin assignments, drain-source voltage, on-resistance and thermal ratings. Use it to confirm gate, source and drain locations when measuring a shorted rail, and to find a suitable replacement in the same footprint. Check the marking code on the chip against the sheet.
