Introduction to Infrared SMD Diode
What is an Infrared SMD Diode?
An infrared SMD diode, also known as an infrared LED (Light Emitting Diode), is a semiconductor device that emits infrared light when an electric current is applied to it. It is widely used in various applications, such as remote controls, communication systems, and security systems. The main advantage of an infrared SMD diode is its compact size, which makes it ideal for integration into small electronic devices.
Working Principle of Infrared SMD Diode
The working principle of an infrared SMD diode is based on the photoelectric effect. When an electric current passes through the diode, electrons and holes are generated in the semiconductor material. When these electrons and holes recombine, they release energy in the form of infrared light. The wavelength of the emitted light is typically between 700 nm and 1500 nm, which falls within the infrared spectrum.
