2N4117
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix 2N4117
The 2N4117 is an Ultra-High Input Impedance N-Channel JFET
The 2N4117 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.
2N4117 Benefits:
Insignificant Signal Loss/Error Voltage
with High-Impedance Source
Low Power Consumption (Battery)
Maximum Signal Output, Low Noise
High Sensitivity to Low-Level Signals
2N4117 Applications:
High-Impedance Transducer
Smoke Detector Input
Infrared Detector Amplifier
Precision Test Equipment

1 . Absolute maximum ratings are limiting values above which 2N4117 serviceability may be impaired.
NOTES
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.)
