Introduction to Infrared LED 3535

The 3535 infrared LED is a surface-mount device (SMD) with a standard package size of 3.5mm x 3.5mm. It is designed to emit infrared light at a wavelength of approximately 940nm, which falls within the near-infrared spectrum. These LEDs are known for their compact size, high efficiency, and long lifespan, making them ideal for a wide range of applications.

How Infrared LED 3535 Works

Infrared LED 3535 operates on the principle of the PN junction, where electrons and holes recombine to release energy in the form of light. When an electric current is applied to the LED, electrons are injected into the n-type semiconductor material, while holes are injected into the p-type material. As these electrons and holes move towards the junction, they recombine and release energy in the infrared region of the electromagnetic spectrum.

The efficiency of an infrared LED is determined by its forward voltage and forward current. The forward voltage is the voltage required to turn the LED on, and the forward current is the current that flows through the LED when it is operating. Infrared LEDs typically have a forward voltage of around 1.2V to 1.4V and a forward current of 20mA to 30mA.
