alfatec GmbH & Co. KG
Your Partner for High-Quality Silicon Carbide Diodes

Silicon carbide diodes - also known as SiC diodes - represent a breakthrough in semiconductor technology. 

Compared to conventional silicon diodes, they offer superior characteristics that make them ideal for a wide range of demanding applications. Silicon carbide is a semiconductor material capable of withstanding voltage ranges up to 2000 V and case temperatures up to 175°C - significantly more than traditional silicon. 

alfatec offers a broad range of high-quality SiC diodes from leading manufacturers such as SemiQ and PNJ, available both as discrete components and in module form.
