Introduction

Infrared transceiver diode, as an essential component in the field of infrared communication, plays a crucial role in modern electronic devices. With the rapid development of the Internet of Things (IoT) and the increasing demand for wireless communication, infrared transceiver diodes have become indispensable in various applications. This article will provide an in-depth introduction to the infrared transceiver diode, covering its working principle, types, applications, and future development trends.

Working Principle of Infrared Transceiver Diode

An infrared transceiver diode is a semiconductor device that converts electrical signals into infrared light and vice versa. It consists of a PN junction, which can generate and detect infrared radiation. When the diode is forward-biased, electrons and holes are injected into the depletion region, causing the diode to emit infrared light. Conversely, when the diode is reverse-biased, it can detect infrared light and convert it into electrical signals. The working principle of an infrared transceiver diode is based on the photoelectric effect. When infrared light is incident on the PN junction, electrons and holes are generated, and the diode generates an electrical current. This current can be amplified and processed to obtain the original signal.
