Diotec Semiconductor AG

Directives like the US or EU "Energy Star" require a reduction in electricity consumption, particularly on ICT power supplies, running 24/7. Diotec's GBU10K-LV input bridge rectifier diode chips have a 10% lower forward voltage drop than the standard GBU10K version. Since two diodes are always conducting per mains half cycle, this results in an overall 20% power savings. Though that might not be a lot per single data server, one has to think about the masses of such devices being worldwide in operation. As such, a simple bridge used in high volumes saves a significant amount of energy, enough to save the demand for entire cities.

Three of four worldwide Diotec factories are equipped with photovoltaic (PV) panels, supplying close to 80% of the company's energy demand. The chips used for the GBU10K-LV are produced in Diotec's German headquarters, where one of two wafer and chip fabs are installed. The electricity for the diffusion furnaces is produced at a large scale by the installed PV plant.

Moreover, Diotec Semiconductor offers a large family of completely lead- and halogen-free devices, mainly in the small signal range. New R&D projects deal with the replacement of high-melting-type lead-based solder alloys used in power components. Either by electric conductive adhesives filled with silver flakes or by silver sintering processes. The molding compound used for the GBU10K-LV is already halogen-free.
