Toshiba datasheet for the TPCA8059-H, a 231 KB PDF. The TPCA8059-H belongs to Toshiba's N-channel power MOSFET range in the SOP Advance package, used in switching stages of laptop DC-DC converters. The document provides pin assignment, on-resistance, gate threshold, gate charge and maximum ratings. Technicians use it to find the gate and drain pins, test for a shorted phase to ground or input, and confirm that a replacement part has matching ratings and the same footprint before soldering.
