Photodiode Circuit Symbol - Electronics Component Diagram #3030277 (License: Personal Use)

This schematic symbol represents a photodiode-a semiconductor device that converts light into electrical current. The two angled arrows denote incoming photons striking the PN junction (vertical bar), while the diagonal line identifies the cathode terminal. Widely used in optical sensors, light meters, and communication receivers, this symbol helps engineers quickly identify light-sensitive components in circuit schematics.

Used in electronics textbooks, datasheets, PCB design software, and educational content to illustrate optoelectronic components; matches user intent for learning circuit symbols or designing light-detection circuits.
