Basic Principles of IR Emitter Diode

IR emitter diode is a semiconductor device made of materials such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide phosphide (InGaAsP). When the diode is forward biased, the electrons and holes in the semiconductor material recombine, releasing energy in the form of infrared light. The wavelength of the emitted light is determined by the composition and structure of the semiconductor material.

The main parameters of IR emitter diodes include:

1. Wavelength: The wavelength of the emitted light is an important parameter for selecting the appropriate application. The common wavelengths of IR emitter diodes are 830nm, 940nm, and 1060nm.

2. Output power: The output power of the IR emitter diode refers to the amount of infrared light emitted by the diode. The output power of commercial IR emitter diodes is generally between 0.1mW and 10mW.

3. Forward voltage: The forward voltage of the IR emitter diode refers to the voltage required to achieve the specified output power. The forward voltage of commercial IR emitter diodes is generally between 1.2V and 3.5V.

4. Operating temperature: The operating temperature of the IR emitter diode refers to the range of temperatures in which the diode can operate normally. The operating temperature of commercial IR emitter diodes is generally between -40℃ and 100℃.
