What is 3216 Infrared LED?

The 3216 infrared LED, also known as the 3216 IR LED, is a type of light-emitting diode (LED) that emits infrared light at a specific wavelength. It is widely used in various applications, including consumer electronics, industrial automation, and medical devices. The 3216 IR LED is known for its compact size, high brightness, and low power consumption, making it a popular choice for designers and engineers looking for efficient and reliable infrared solutions. In the following sections, we will delve into the details of the 3216 infrared LED, its applications, and the advantages it offers over other types of infrared emitters.

How Does the 3216 Infrared LED Work?

The 3216 IR LED operates based on the principle of the PN junction. When an electric current is applied to the diode, electrons and holes are injected into the PN junction. As these charge carriers recombine, they release energy in the form of photons. In the case of the 3216 IR LED, these photons are emitted at a specific infrared wavelength, typically between 780 nm and 940 nm. The 3216 IR LED is constructed using a gallium arsenide (GaAs) or gallium indium phosphide (GaInP) semiconductor material, which has excellent infrared emission properties. The compact size of the 3216 IR LED is achieved by integrating the semiconductor material into a small package, typically measuring 3.2 mm x 1.6 mm. The 3216 IR LED emits light in a forward direction, which is why it is often used in applications that require a directional infrared beam. The emitted light can be focused and directed using lenses or optical components, depending on the specific application requirements.
