Introduction to the 1206 Infrared LED Diode

What is a 1206 Infrared LED Diode?

The 1206 Infrared LED diode, also known as an SMD (Surface Mount Device) infrared LED, is a compact and highly efficient component used in various applications that require the detection or emission of infrared light. Measuring just 1.2mm x 0.6mm, this tiny diode is designed to fit into tight spaces without compromising its performance. Infrared LEDs emit light in the infrared spectrum, which is not visible to the human eye, and are widely used in remote controls, barcode scanners, and communication systems.

Working Principle

The 1206 Infrared LED diode operates based on the principle of electroluminescence. When an electric current is applied to the diode, it emits photons in the infrared spectrum. The diode is made up of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which has a direct bandgap that allows it to emit infrared light efficiently. The semiconductor material is sandwiched between a p-type and an n-type layer, which creates a PN junction. When electrons from the n-type material recombine with holes from the p-type material, they release energy in the form of infrared light.
