The 4mm size makes them highly versatile, suitable for integration into compact devices and systems.

How 4mm Infrared LED Diodes Work

4mm Infrared LED diodes operate on the principle of the PN junction, where an electric current passes through a semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP), to emit light. When the diode is forward biased, electrons and holes recombine at the PN junction, releasing energy in the form of photons. In the case of infrared LEDs, these photons fall within the infrared spectrum, which is not visible to the naked eye.
