Central Semiconductor Corp. JFETs PN4391 PBFREE

The PN4391 is an N-channel silicon JFET in a TO-92 package, designed for analog switching and chopper applications. It has a gate-drain and gate-source voltage rating of 40 V, a maximum gate current of 50 mA, and a power dissipation of 625 mW. The device operates over a junction temperature range of -65 to +150 °C. Key electrical characteristics include a drain-source saturation current (IDSS) of 50 to 150 mA at VDS=20 V and a gate-source pinch-off voltage (VGS(OFF)) of 4.0 to 10 V at VDS=20 V and ID=1.0 nA. On-resistance (rDS(ON)) is specified up to 30 Ω at ID=1.0 mA and VGS=0. The part complies with RoHS standards.
