DESCRIPTION
The 2N3819 is a low-cost, all-purpose JFET which offers good
performance at mid-to-high frequencies. It features low noise
and leakage and guarantees high gain at 100 MHz.
Its TO-226AA (TO-92) package is compatible with various
tape-and-reel
options
for
automated
assembly
(see
Packaging Information). For similar products in TO-206AF
(TO-72)
and
TO-236
(SOT-23)
packages,
