Introduction to Infrared Transceiver Diode

What is an Infrared Transceiver Diode?

An infrared transceiver diode, also known as an infrared photodiode, is a semiconductor device that is used to detect and emit infrared radiation. It is widely used in various applications, such as remote controls, wireless communication, and optical sensors. The device consists of a p-n junction, which allows it to emit and detect infrared light. When an infrared signal is emitted, the diode converts it into an electrical signal, and vice versa.

Working Principle of Infrared Transceiver Diode

The working principle of an infrared transceiver diode is based on the photoelectric effect. When infrared light falls on the diode, it generates an electric current. This current is proportional to the intensity of the infrared light. Conversely, when an electric current is applied to the diode, it emits infrared light. The infrared transceiver diode is designed to operate in the infrared spectrum, which ranges from 700 nm to 1 mm.
