Introduction to IR Diode SMD

What is an IR Diode SMD?

An IR diode SMD, or Surface Mount Device, is a type of electronic component that emits infrared radiation when an electrical current passes through it. This category of diodes is widely used in various applications, including remote controls, fiber optic communication, and optical sensors. The SMD technology allows for compact and efficient design, making IR diodes SMD an essential component in modern electronics.

Working Principle of IR Diode SMD

The working principle of an IR diode SMD is based on the semiconductor physics. When a forward voltage is applied across the diode, electrons and holes are injected into the depletion region, causing recombination. This recombination process releases energy in the form of photons, which are infrared light. The intensity of the emitted light is directly proportional to the current flowing through the diode.
