Optimize IR Photo Diode Performance: Essential Insights & Tips

IR photo diode, also known as infrared photo diode, is a type of semiconductor photodetector that can convert infrared light into electrical signals. It plays a crucial role in various applications, such as remote control, infrared communication, and thermal imaging. In this article, we will explore the industry of IR photo diodes, covering their working principles, applications, market trends, and future prospects.

Working Principle of IR Photo Diode

The IR photo diode is based on the photoelectric effect, which occurs when a photon with sufficient energy strikes a semiconductor material. When the photon is absorbed by the semiconductor, it generates an electron-hole pair, leading to the generation of an electrical current. The energy of the absorbed photon is directly related to the bandgap of the semiconductor material. For IR photo diodes, the bandgap is designed to be suitable for the detection of infrared light, typically ranging from 0.9 to 3.0 eV.

IR photo diodes can be divided into two types: PIN diodes and APD ( Avalanche Photo Diode) diodes. PIN diodes are commonly used for low-cost applications, such as remote control and infrared communication. APD diodes, on the other hand, are suitable for high-sensitivity applications, such as thermal imaging and long-distance communication.
