Photodiode Symbol - Electronic Component Diagram & Explanation #1498780 (License: Personal Use)

This black-and-white schematic symbol represents a photodiode in electronic circuit diagrams. The vertical rectangle denotes the semiconductor junction, with two angled arrows indicating incident light, and a diagonal line across the circle signifying the cathode side (P-N junction orientation). It conveys both optical sensitivity and directional current flow under illumination.

Used in technical documentation, educational materials, datasheets, and PCB design software to represent photodiodes in schematics; matches user intent for learning component symbols, designing light-sensing circuits, or interpreting circuit diagrams.
