DESCRIPTION
The 2N/PN/SST4117A series of n-channel JFETs provide
ultra-high input impedance. These devices are specified with
a 1-pA limit and typically operate at 0.2 pA. This makes them
perfect choices for use as high-impedance sensitive front-end
amplifiers.
The hermetically sealed TO-206AF package allows full
military processing per MIL-S-19500 (see Military
Information). The TO-226A (TO-92) plastic package provides
a low-cost option. The TO-236 (SOT-23) package provides
surface-mount capability. Both the PN and SST series are
available in tape-and-reel for automated assembly (see
Packaging Information).
