Infrared SMD diode, as a key component in the infrared detection field, plays a crucial role in various applications such as security, communication, and industrial automation. With the continuous development of technology, the demand for infrared SMD diodes is increasing. This article will introduce the industry of infrared SMD diodes, including its working principle, types, applications, and market trends.

Working Principle of Infrared SMD Diode

Infrared SMD diode is a semiconductor device that can emit and detect infrared radiation. Its working principle is based on the photoelectric effect. When the infrared SMD diode is exposed to infrared radiation, it can generate a photoelectric current. The intensity of the photoelectric current is proportional to the intensity of the infrared radiation. This principle is used to detect and measure infrared radiation. The structure of an infrared SMD diode mainly includes a p-n junction. When the p-n junction is forward biased, the infrared radiation will be emitted. When the p-n junction is reverse biased, the infrared radiation will be detected. The emitted and detected infrared radiation can be used for various applications, such as remote control, infrared communication, and infrared obstacle avoidance.

Types of Infrared SMD Diodes

Infrared SMD diodes can be divided into two main categories according to their functions: infrared emitting diodes and infrared receiving diodes. 1. Infrared Emitting Diode (LED) Infrared emitting diodes are used to emit infrared radiation. They have the following characteristics: - High efficiency: The infrared emitting diode can convert a large amount of electrical energy into infrared radiation. - Wide spectrum: The infrared emitting diode can emit infrared radiation in the entire infrared spectrum. - Long service life: The infrared emitting diode has a long service life due to its stable performance. 2. Infrared Receiving Diode Infrared receiving diodes are used to detect infrared radiation. They have the following characteristics: - High sensitivity: The infrared receiving diode can detect weak infrared radiation. - Fast response: The infrared receiving diode has a fast response time to infrared radiation. - Low noise: The infrared receiving diode has low noise, ensuring the accuracy of the detection results.
