High Power Die

High Power Die

Plessey manufactures low cost high efficiency high power GaN-on-Silicon blue die. The die can be customised and packaged for a wide range of applications in general lighting including industrial, retail, hospitality and outdoor applications. The die can be assembled as single devices or in strings or arrays for example in chip on board (CoB) designs.

The patented manufacturing process produces a surface emitting structure which has excellent light uniformity and thermal conductivity. Die can be supplied in industry standard sizes up to a maximum of 100mil square. The die technology supports forward voltages between 3V and 48V.

Plessey offers its family of blue die in a range of wavelength options, to cover uses from near UV medical products to visible blue light sources. The standard product provides the blue pump for phosphor conversion to white light.
