Introduction to 3mm Infrared Transmitter Diode

A 3mm infrared transmitter diode, also known as a 3mm IR LED, is a semiconductor device that emits infrared light when an electric current is applied to it. The device consists of a PN junction, where the P-type and N-type semiconductor materials are joined together. When an electric current passes through the diode, it generates heat, which causes the electrons and holes to recombine. This recombination process releases energy in the form of photons, which are emitted as infrared light.

The 3mm infrared transmitter diode is a compact and efficient device, making it an ideal choice for various applications. It emits light at a specific wavelength, typically ranging from 780 nm to 950 nm, which falls within the infrared spectrum. This wavelength is invisible to the human eye, making it suitable for applications where light visibility is not required.

Working Principle of 3mm Infrared Transmitter Diode

The working principle of a 3mm infrared transmitter diode is based on the PN junction. When an electric current is applied to the diode, electrons from the N-type semiconductor material are attracted to the holes in the P-type material. As these electrons and holes recombine, they release energy in the form of photons. The wavelength of the emitted light depends on the energy gap between the valence and conduction bands of the semiconductor material.

The 3mm infrared transmitter diode operates at a forward bias, meaning that the positive terminal of the power supply is connected to the P-type material, and the negative terminal is connected to the N-type material. This creates a potential difference across the PN junction, allowing the electric current to flow. The forward bias voltage required for the diode to operate is typically around 1.2 to 1.5 volts.
