Indexed as a schematic, this 175 KB PDF is named 80EPF10, a code following International Rectifier style for a rectifier diode part rather than a board number. Expect a datasheet with package details, terminal layout and electrical characteristics; no device or brand is mentioned. Technicians use such sheets when diagnosing a shorted or open diode and choosing a compatible substitute. Related 80EPF02 sheets appear in the index, so confirm the digits on the component match this one.
