Bipolar Transistors DIOTEC

(348)
 
Bipolar Transistors
Choose from our offer of 348 DIOTEC products in the Bipolar Transistors category. SOS electronic is a specialized distributor of DIOTEC. Apart from the components delivery, we can also provide technical support directly from the manufacturer and samples needed for development.
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.
