Introduction to Infrared LED 3535

What is an Infrared LED 3535?

An infrared LED 3535 is a type of light-emitting diode (LED) that emits infrared light. It is a compact, surface-mount device with a 3.5mm x 3.5mm footprint. The 3535 size is a popular choice for various applications due to its small size and high efficiency. Infrared LEDs are widely used in consumer electronics, medical devices, and industrial applications for communication, sensing, and illumination purposes.

How Does an Infrared LED 3535 Work?

Infrared LEDs work on the principle of electroluminescence, where an electric current is passed through a semiconductor material, causing it to emit light. The semiconductor material used in infrared LEDs is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When the current passes through the semiconductor, it generates heat, which is dissipated through a heat sink or thermal pad. The emitted light is in the infrared spectrum, which is not visible to the human eye.
