Introduction to Infrared Transmitter SMD Diode

What is an Infrared Transmitter SMD Diode?

An infrared transmitter SMD diode, also known as an infrared LED (Light Emitting Diode), is a semiconductor device that emits infrared light when an electric current is applied to it. It is widely used in various applications, such as remote controls, wireless communication, and consumer electronics. In this article, we will delve into the details of infrared transmitter SMD diodes, their working principles, applications, and the advantages they offer over other types of diodes.

Working Principle of Infrared Transmitter SMD Diode

The working principle of an infrared transmitter SMD diode is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are generated in the semiconductor material. These charge carriers recombine at the junction, releasing energy in the form of photons. The wavelength of these photons falls within the infrared region of the electromagnetic spectrum, which is not visible to the human eye. The semiconductor material used in infrared transmitter SMD diodes is typically gallium arsenide (GaAs) or gallium phosphide (GaP). These materials have a direct bandgap, which allows them to efficiently emit infrared light. The forward voltage required to operate the diode varies depending on the material and the desired wavelength of the emitted light.
