Custom Parts

Over 50% of our business is JFET custom solutions. Customers usually start with standard parts and customize them for their application. Many parameters are customizable, but the trade-offs must be considered for your application. Higher Idss or Gm typically requires a higher pinch-off voltage (Vp). Higher gain parts always have higher Ciss and Igss.

If starting from standard parts and customizing is impractical, consider starting from scratch with a geometry selection.
