Photodiode

Layout symbol

Diode that lets a small current flow when light hits it. Usually connected in reverse (cathode toward the positive supply) with a resistor, so the voltage across the resistor rises with more light. The current is tiny, so it's often followed by an amplifier. Very fast, used in IR receivers and light measurement. Learn more about photodiodes
