F4901 11a 24v Schematic Top -

The number F4901 is almost certainly not the base part number. It is a date/lot code.

The trick: Look at the physical package (SOT-23-6? SOIC-8? TO-252?). Measure pin-to-ground resistance. A 24V, 11A rating suggests a high-side load switch, buck converter, or linear regulator with a pass transistor. f4901 11a 24v schematic top

This is the standard view for wiring diagrams. The number F4901 is almost certainly not the

Note on Polarity:

The primary side of the F4901 11A 24V schematic carries lethal voltages (up to 370V DC). Follow these rules: The trick: Look at the physical package (SOT-23-6
