Infrared LED 5mm: A Brief Overview

The 5mm infrared LED, also known as an infrared emitting diode, is a compact and versatile component widely used in various applications. With its small size and high efficiency, the 5mm infrared LED has become an essential component in the field of electronics. In this article, we will delve into the details of the 5mm infrared LED, its applications, and the advantages it offers over other types of LEDs.

What is an Infrared LED 5mm?

An infrared LED 5mm is a semiconductor device that emits infrared light when an electric current is applied to it. It consists of a p-n junction, where the p-type and n-type materials are combined to create a forward-biased diode. When the diode is forward-biased, electrons and holes recombine at the junction, releasing energy in the form of infrared light. The 5mm refers to the diameter of the LED's lens, which is typically 5 millimeters. This small size makes the 5mm infrared LED suitable for compact applications where space is limited. The infrared light emitted by the LED is invisible to the human eye, which makes it ideal for applications that require stealth or covert operations.
