Introduction to Infrared Transmitter SMD Diode

Infrared transmitter SMD diodes are semiconductor devices that emit infrared light when an electric current passes through them. They are typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) materials, which have excellent infrared emission properties. These diodes are characterized by their small size, low power consumption, and high efficiency, making them ideal for integration into compact electronic devices.

How Infrared Transmitter SMD Diodes Work

The working principle of an infrared transmitter SMD diode is based on the photoelectric effect. When an electric current is applied to the diode, electrons are excited from the valence band to the conduction band, creating a depletion region. This region is filled with positively charged holes and negatively charged electrons. As the electrons recombine with the holes, they release energy in the form of photons, which are emitted as infrared light. The emitted light is typically in the near-infrared spectrum, which is invisible to the human eye. The wavelength of the emitted light can be controlled by the composition and structure of the diode material. Infrared transmitter SMD diodes are available in a range of wavelengths, from 780 nm to 950 nm, to cater to different applications.
