Introduction to 3216 Infrared LED Technology

What is a 3216 Infrared LED?

The 3216 infrared LED, also known as a 3216 infrared emitting diode, is a compact and highly efficient light source that emits infrared radiation. This type of LED is widely used in various applications, including consumer electronics, automotive, medical devices, and industrial automation. The "3216" refers to the physical dimensions of the LED, which are 3.2mm x 1.6mm. This size makes the 3216 LED particularly suitable for space-constrained environments where high-intensity infrared light is required.

How Does a 3216 Infrared LED Work?

Like other LEDs, the 3216 infrared LED consists of a semiconductor material, typically gallium arsenide (GaAs), which emits light when an electric current passes through it. In the case of infrared LEDs, the semiconductor material is designed to emit light in the infrared spectrum, which is not visible to the human eye. When the LED is powered, electrons and holes recombine at the PN junction, releasing energy in the form of photons. These photons are then emitted as infrared light.
