2N4118A  
N-CHANNEL JFET  
Linear Systems replaces discontinued Siliconix 2N4118A  
The 2N4118A is an Ultra-High Input Impedance N-Channel JFET  
FEATURES  
The 2N4118A provides ultra-high input impedance. The  
device is specified with a 1-pA limit and typically  
operates at 0.2 pA. The part is ideal for use as a high-  
impedance sensitive front-end amplifier.

1 . Absolute maximum ratings are limiting values above which 2N4118A 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.)
