Introduction to 1206 UV LED Diode

The 1206 UV LED diode, also known as the 0603 UV LED, is a type of ultraviolet light-emitting diode that measures just 1.2mm x 0.6mm in size. Despite its small form factor, it packs a significant punch in terms of output and efficiency. These diodes are typically made using gallium nitride (GaN) or aluminum gallium nitride (AlGaN) as the semiconductor material, which enables them to emit UV light at a wavelength ranging from 365nm to 400nm.

Working Principle of 1206 UV LED Diode

The 1206 UV LED diode operates on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing electrons to recombine with electron holes, releasing energy in the form of photons. In the case of UV LEDs, the photons have a shorter wavelength and higher energy compared to visible light, which makes them ideal for applications that require UV radiation. The diode consists of a p-n junction, where the p-type and n-type semiconductor materials are joined together. When a forward bias voltage is applied across the diode, electrons from the n-type material move towards the p-type material, recombining with holes and emitting UV light. The efficiency of the 1206 UV LED diode is determined by the quality of the semiconductor material, the design of the diode, and the heat dissipation mechanism.
