J230 SERIES
N-Channel JFETs
The J230 Series of popular, low-cost JFETs offers
high performance in a wide range of applications. It
features low leakage, noise and cutoff voltage for
use with low level power supplies. Its TO-92
package offers both value and compatibility with
automated assembly.
For further design information please consult the
typical performance curves NPA which are located
in Section 7.
