Toshiba TPCA8030-H datasheet, a 168 KB PDF for a power MOSFET in a small surface-mount package used in notebook voltage regulators. When a rail is shorted to ground, this sheet lets you confirm which pins are gate, drain and source and what on-resistance and voltage rating to expect. It is also handy for picking an equivalent transistor when the original is unavailable. Match the marking on the board part to the document and compare the package outline before soldering a substitute.
