Introduction to the 1206 Infrared LED Diode

What is a 1206 Infrared LED Diode?

The 1206 Infrared LED diode, also known as an SMD (Surface Mount Device) infrared LED, is a compact and efficient light source that emits infrared radiation. These diodes are widely used in various applications, including remote controls, security systems, and medical devices. The 1206 size refers to the physical dimensions of the LED, which are 1.2mm x 0.6mm, making them one of the smallest types of infrared LEDs available.

Working Principle

The 1206 Infrared LED diode operates on the principle of electroluminescence. When an electric current is applied to the diode, it emits infrared light. The diode consists of a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emits infrared radiation when excited by an electric current. The emitted light is typically in the near-infrared spectrum, which is not visible to the human eye.
