Photodiode Symbol - Electronic Component Diagram Representation #1261228 (License: Personal Use)

This is the universally recognized schematic symbol for a photodiode-a semiconductor device that converts light into electrical current. The circle denotes the component body, the two vertical bars represent the P-N junction, the dot indicates the cathode, and the horizontal line signifies the electrical connection; some variants include an arrow pointing inward to denote light incidence. It's used in circuit diagrams across engineering disciplines to signal optoelectronic functionality.

Used in electronic schematics, datasheets, educational materials, and PCB design software to represent photodiodes in circuits involving light detection, optical communication, or sensing applications. Matches user intent for technical reference, component identification, or learning electronics symbols.
