PN4119
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix PN4119
The PN4119 is an Ultra-High Input Impedance N-Channel JFET
FEATURES
The PN4119 provides ultra-high input impedance. The
device is specified with a 10-pA limit and is ideal for use
as a high-impedance sensitive front-end amplifier.

1 . Absolute maximum ratings are limiting values above which PN4119 serviceability may be impaired.
2. Due to symmetrical geometry, these units may be operated with source and drain leads interchanged
3. This parameter is measured during a 2ms interval 100ms after power is applied. (Not a JEDEC condition.)
