Definition and Classification of IR Detector Diode

The infrared detector diode is a semiconductor device that can convert infrared radiation into electrical signals. It is widely used in various fields, such as military, aerospace, industrial automation, medical, and consumer electronics. According to the detection principle, IR detector diodes can be divided into two main categories: thermal infrared detector diodes and photoelectric infrared detector diodes.

Working Principle of IR Detector Diode

The working principle of an IR detector diode is based on the photoelectric effect and the thermal effect. When infrared radiation is incident on the surface of the diode, the photons with sufficient energy can excite electrons in the semiconductor material, causing the electrons to jump from the valence band to the conduction band. This process generates an electrical signal, which can be amplified and processed for further application.
