3535 infrared LED, also known as a 3535 infrared emitting diode, is a type of light-emitting diode (LED) that emits infrared light. These LEDs are widely used in various applications due to their compact size, high efficiency, and low cost. In this article, we will delve into the details of 3535 infrared LEDs, their applications, and the industry trends surrounding them.

Introduction to 3535 Infrared LEDs

3535 infrared LEDs are a type of LED that belongs to the SMD (Surface Mount Device) category. They are characterized by their small package size, which measures 3.5mm x 3.5mm. This compact size makes them highly suitable for applications where space is limited. The 3535 package is also known as the 0603 package, which is a standard in the electronics industry.

These LEDs emit light in the infrared spectrum, which is not visible to the human eye. The infrared light produced by 3535 infrared LEDs is typically in the range of 780nm to 950nm. This makes them ideal for applications that require invisible light, such as remote controls, infrared sensors, and security systems.

Working Principle of 3535 Infrared LEDs

Like other LEDs, 3535 infrared LEDs work on the principle of electroluminescence. When an electric current is applied to the LED, electrons recombine with electron holes within the semiconductor material, releasing energy in the form of light. In the case of infrared LEDs, this energy is in the infrared spectrum, which is not visible to the naked eye.

The semiconductor material used in 3535 infrared LEDs is typically a combination of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). These materials have a direct bandgap, which allows them to efficiently emit infrared light when excited by an electric current.
