Introduction

The 0805 LED diode, also known as an SMD (Surface Mount Device) LED, has become a staple in the electronics industry due to its compact size, high efficiency, and versatility. This article aims to provide an in-depth introduction to the 0805 LED diode, exploring its features, applications, and the market trends surrounding this popular component.

What is a 0805 LED Diode?

A 0805 LED diode is a type of light-emitting diode (LED) that measures only 2.0mm x 1.25mm in size. The name "0805" refers to the component's physical dimensions in millimeters, with the first two digits representing the length and the last two digits representing the width. This compact size makes the 0805 LED diode ideal for applications where space is limited, such as in mobile devices, wearable technology, and automotive lighting. The 0805 LED diode operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The color of the emitted light depends on the type of semiconductor material used, such as gallium nitride (GaN), silicon carbide (SiC), or aluminum gallium indium phosphide (AlGaInP).
