Introduction to 0805 UV LED Diodes

The 0805 UV LED diode is a type of light-emitting diode (LED) that measures just 0.08 inches by 0.05 inches in size. Despite their small size, these diodes are capable of producing intense UV light, making them suitable for a variety of applications. The 0805 UV LED diode is part of the SMD (Surface Mount Device) family, which includes other popular sizes like 0603, 0402, and 0201.

How 0805 UV LED Diodes Work

Similar to other LED diodes, the 0805 UV LED diode consists of a semiconductor material that emits light when an electric current passes through it. In the case of UV LEDs, the semiconductor material is specifically designed to emit UV light. When the current flows through the diode, the electrons recombine with the holes in the semiconductor, releasing energy in the form of UV light. The efficiency of a UV LED diode is determined by its forward voltage and forward current. The forward voltage is the voltage required to turn the diode on, while the forward current is the current that flows through the diode when it is turned on. The color and intensity of the UV light emitted by the diode depend on the semiconductor material used and the design of the diode.
