How 3535 Infrared LED Diodes Work

The 3535 Infrared LED Diode operates on the principle of the PN junction, which is a semiconductor device that emits light when an electric current passes through it. When a forward voltage is applied to the diode, electrons and holes recombine at the PN junction, releasing energy in the form of photons. In the case of an infrared LED, these photons fall within the infrared spectrum, which is not visible to the human eye. The 3535 Infrared LED Diode typically has a forward voltage of around 1.2V to 1.5V and a forward current of 20mA to 30mA. The diode's efficiency is determined by its ability to convert electrical energy into light, with higher efficiency resulting in less heat generation and longer lifespan.

Design Considerations for 3535 Infrared LED Diodes

When designing circuits that incorporate 3535 Infrared LED Diodes, several factors need to be considered to ensure optimal performance: 1.
