J204  
N-CHANNEL JFET  
Linear Systems replaces discontinued Siliconix J204  
The J204 is a high gain N-Channel JFET  
FEATURES  
This n-channel JFET is optimised for high gain. The  
DIRECT REPLACEMENT FOR SILICONIX J204  
LOW CUT OFF VOLTAGE

part is particularly suitable for use in low power or high  
impedance amplifiers. The TO-92 package is well  
suited for cost sensitive applications and mass  
production.
