How 0805 Infrared LED Diodes Work

0805 Infrared LED Diodes work on the principle of the photoelectric effect. When an electric current is applied to the diode, it emits infrared light due to the recombination of electrons and holes in the semiconductor material. The infrared light is then emitted in a specific direction, which can be controlled by the design of the LED's housing. The semiconductor material used in 0805 Infrared LED Diodes is typically a combination of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light at a specific wavelength. The most common wavelengths for 0805 Infrared LED Diodes are 940 nm and 870 nm, although other wavelengths are also available to suit specific applications.
