3-5 Power Electronics is a start-up company that has set up its development and production site in the Dresden Technology Center. The company focuses on innovative semiconductors for power electronics. The development team, which has now grown to ten highly specialized engineers, has succeeded in conditioning the widely used semiconductor material gallium arsenide (GaAs) in such a way that it can be used for the construction of diodes for switching high voltages and currents. 

The evaluations of the electrical properties confirm a higher efficiency compared to the commonly used silicon diodes. An additional positive aspect is the significantly more cost-effective manufacturing technology compared to silicon carbide diodes.
