This article aims to provide an in-depth introduction to the 3mm infrared transmitter diode, covering its working principle, applications, advantages, and market trends.

Introduction to 3mm Infrared Transmitter Diode

The 3mm infrared transmitter diode, also known as a 3mm IR LED, is a semiconductor device that emits infrared light when an electric current is applied. It is a type of diode that is designed to produce light in the infrared spectrum, which is not visible to the human eye. The 3mm size refers to the diameter of the diode, making it a compact option for various applications where space is limited.

Working Principle

The 3mm infrared transmitter diode operates based on the principle of electroluminescence. When an electric current is passed through the diode, electrons and holes are recombined at the junction between the p-type and n-type semiconductor materials. This recombination releases energy in the form of photons, which are emitted as infrared light.

The wavelength of the emitted light depends on the composition of the semiconductor materials used in the diode. For 3mm infrared transmitter diodes, the typical wavelength range is between 780nm to 950nm, which falls within the near-infrared region.
