This article aims to provide an in-depth introduction to the infrared transmitter diode model, its working principle, types, applications, and future trends.

Working Principle of Infrared Transmitter Diode Model

The infrared transmitter diode model operates based on the principle of the PN junction. When a forward bias voltage is applied across the diode, electrons from the n-type semiconductor migrate towards the p-type semiconductor, while holes move towards the n-type semiconductor. This results in the recombination of electrons and holes, releasing energy in the form of infrared radiation. The process can be summarized as follows: 1. Forward bias voltage is applied to the diode. 2. Electrons and holes recombine at the PN junction. 3. Energy is released in the form of infrared radiation. The intensity of the emitted infrared radiation depends on various factors, such as the forward bias voltage, temperature, and the material composition of the diode.
