Infrared receiver diode, as a key component in the field of infrared communication technology, plays a crucial role in converting infrared signals into electrical signals. This article aims to provide an in-depth introduction to the infrared receiver diode industry, covering its definition, working principle, types, applications, and market trends.

Definition and Classification of Infrared Receiver Diode

An infrared receiver diode is a semiconductor device that converts infrared light into electrical signals. It is widely used in various fields, such as consumer electronics, automotive, medical equipment, and industrial automation. According to the working principle, infrared receiver diodes can be divided into two types: photoelectric receiver diodes and photoconductive receiver diodes.

Working Principle of Infrared Receiver Diode

The working principle of an infrared receiver diode is based on the photoelectric effect. When the infrared light is incident on the surface of the diode, the photons with sufficient energy will excite the electrons in the semiconductor material, causing the electrons to move to the conduction band and generate an electrical signal. The intensity of the electrical signal is proportional to the intensity of the incident infrared light.

Types of Infrared Receiver Diode

1. PIN photodiode: A PIN photodiode is a three-layer semiconductor structure, which has a good photoelectric conversion effect and is widely used in high-speed and long-distance infrared communication systems. 2. APD ( Avalanche Photodiode): An APD is a high-sensitivity photodiode with a high-speed response. It can amplify the electrical signal generated by the photoelectric effect, which is suitable for weak light detection and long-distance communication. 3. PIN photodiode with a Schottky diode: This type of photodiode combines the PIN photodiode and the Schottky diode, which has the advantages of high sensitivity and fast response, and is suitable for short-distance infrared communication systems.

Applications of Infrared Receiver Diode

1. Consumer electronics: Infrared receiver diodes are widely used in remote controls, TV remote controls, and other consumer electronics products. 2. Automotive: Infrared receiver diodes are used in automotive rearview cameras, parking assist systems, and other automotive electronic devices. 3.
