Introduction

Infrared SMD diodes, also known as infrared emitting diodes, are widely used in various applications due to their compact size, high efficiency, and reliable performance. As the demand for infrared technology continues to grow, the market for infrared SMD diodes is also expanding rapidly. This article aims to provide an in-depth introduction to the industry of infrared SMD diodes, covering their working principle, applications, market trends, and future prospects.

Working Principle of Infrared SMD Diodes

Infrared SMD diodes are semiconductor devices that emit infrared radiation when an electric current passes through them. The working principle of an infrared SMD diode is based on the principle of the PN junction. When the diode is forward biased, electrons and holes are injected into the depletion region, leading to recombination and the emission of infrared photons. The infrared radiation emitted by the diode is determined by the bandgap energy of the semiconductor material used. Different materials have different bandgap energies, resulting in different wavelengths of infrared radiation. For example, a diode made of gallium arsenide (GaAs) emits infrared radiation with a wavelength of 850 nm, while a diode made of indium gallium arsenide phosphide (InGaAsP) emits infrared radiation with a wavelength of 1550 nm.
