Manufacturer DIOTEC
The heart of a semiconductor device is the silicon chip. While many suppliers just buy the chips and assemble them into a package, Diotec has got the complete know how of semiconductor production. Especially Zener and TVS diodes, with their large variety of partnames, are a major challenge with respect to base material, logistics and diffusion technology.
  • Diotec itself produces silicon chips – not only assembles them to package
  • wide portfolio
  • double 100% testing of electrical parameters
Did you know?
Diotec is one of the market leaders in this field, offering one of the widest range of products and fastest delivery time. Diotec newly produces also diodes for LED applications, ESD protection as well as diodes in new small SMT packages with enhanced power rating.
