In this article, we will delve into the world of infrared beam diodes, exploring their working principles, types, applications, and future trends.

Working Principle of Infrared Beam Diode

The infrared beam diode operates based on the principle of semiconductor physics. When an electric current is applied to the diode, electrons and holes are injected into the p-n junction, leading to the recombination of electrons and holes.
