Working Principle of IR Diode SMD

An IR Diode SMD operates on the principle of the光电效应, where electrons are emitted from the n-type semiconductor material when it is forward biased. These electrons combine with the holes in the p-type semiconductor, resulting in the release of infrared radiation. The emitted radiation has a wavelength range of 700 to 3000 nanometers, which is invisible to the human eye. The intensity of the emitted radiation depends on the forward current and the physical characteristics of the diode. The IR Diode SMD is typically made of materials like gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs). These materials have excellent electrical and optical properties, making them suitable for IR Diode SMD applications. The diode is encapsulated in a small package, which protects the internal structure and ensures efficient heat dissipation.
