Introduction to Infrared SMD Diode
What is an Infrared SMD Diode?
An infrared SMD diode, also known as an infrared emitting diode (IRED), is a type of semiconductor device that emits infrared radiation when an electric current is applied to it. These diodes are widely used in various applications, including remote controls, sensors, and communication systems. The SMD (Surface Mount Device) technology allows for compact and efficient integration into electronic circuits.
How Does an Infrared SMD Diode Work?
An infrared SMD diode consists of a p-n junction, where the p-type and n-type semiconductor materials are joined together. When a forward bias voltage is applied to the diode, electrons from the n-type material move towards the p-type material, and holes from the p-type material move towards the n-type material. This movement of charge carriers creates a recombination process, which emits infrared radiation.
The emitted infrared radiation has a wavelength range of approximately 700 to 1500 nanometers. This range is suitable for various applications, such as infrared remote controls, night vision devices, and optical communication systems.
