Datasheet for the AON6414A MOSFET from Alpha and Omega Semiconductor, a 268 KB PDF without a manufacturer tag in the name. The part is common in DC-DC converter stages on notebook boards, where a shorted MOSFET often pulls a rail to ground. Use the sheet to confirm which pads are gate, source and drain, and to compare voltage, current and on-resistance ratings when looking for a replacement. Verify the top marking on the component, since visually similar parts can have quite different specifications.
