2N4391-2-3

2N4391, 2N4392, 2N4393 N-Channel JFET

Features
� InterFET N0132S Geometry � Low Noise: 1.2 nV/Hz Typical � Fast Switching � Low Cutoff Voltage: 2N4393 < 3.0V � RoHS Compliant � SMT, TH, and Bare Die Package options.
Applications
� Low On Resistance Analog Switches � Choppers � Commutators
Description
The -40V InterFET 2N4391, 2N4392 and 2N4393 are targeted for switch, chopper and commutator designs. Gate leakages are typically less than 50pA at room temperatures. The 2N4393 has a cutoff voltage of less than 3.0V ideal for low-level power supplies. The TO-18 package is hermetically sealed and suitable for military applications.
