This report combines the analysis of two components in order to offer a broad vision of the technologies used by UVC LEDs in terms of applications and power output. The UVTOP270TO39HS and SS35DF227513 are two 275nm UVC LEDs from Sensor Electronic Technology Inc. (SETi). The UVTOP270TO39HS, with its hemispherical lens and 0.1mm² LED, is adapted for fluorescent spectroscopy and chemical/biological analysis. The SS35DF227513, with its flat window, is designed for disinfection.

The two LED dies are based on the same technology: an AlN template layer deposited on a sapphire substrate. The AlGaN active layers are epitaxied on the AlN layer, but the thickness is very different between the two dies. The SS35DF227513 is manufactured using the latest SETi technological evolution. The new AlN and AlGaN structure reduces the defect density to enhance external quantum efficiency. At 1mm², the SS35DF227513 is 9x taller than SETi’s first UVC LED and boasts 15x more power.

The TO39 with a hemispherical lens is an expensive package, but it is destined for instrumentation. The new SMD3535 package in the SS35DF227513’s ceramic is cheaper and designed for disinfection with a large viewing angle and better thermal resistance that allows continuous use of the 1mm² LED.

This report delivers a deep technology analysis of the packaging and the components, with images of the complex AlN and AlGaN epitaxy layer stack and electrode structure. Also included are a production cost analysis and an overall comparison with the first SETi UVC LED.
