The 2N4391 is an N-channel silicon JFET for analog switching and chopper applications, in a TO-18 package. It has a maximum gate-drain and gate-source voltage of 40 V, power dissipation of 1.8 W at TC=25°C, and operates from -65 to +175°C. Drain-source saturation current (IDSS) ranges from 50 to 150 mA at VDS=20 V. Gate-source cutoff voltage (VGS(OFF)) is 4.0 to 10 V at VDS=20 V and ID=1.0 nA. On-state resistance (rDS(ON)) is up to 30 Ω at ID=1.0 mA and VGS=0. Gate-source leakage (IGSS) is 0.1 nA at 25°C. Input capacitance (Ciss) is 14 pF at VDS=20 V and f=1.0 MHz. Rise time (tr) is 5.0 ns for ID(ON)=12 mA. Turn-off time (toff) is 20 ns with VGS(OFF)=12 V.
