The InterFET 2N4391 is an N-Channel JFET designed for switch, chopper, and commutator applications. It offers a low noise characteristic of 1.2 nV/√Hz typical and fast switching speeds.
Key electrical specifications include a Gate to Source Breakdown Voltage of -40V and a Drain to Source Saturation Current of 50mA (typical for 2N4391). The Gate to Source Cutoff Voltage varies by model, with the 2N4393 having a cutoff voltage less than 3.0V, making it suitable for low-level power supplies.
Available in multiple package options including Through-Hole TO-18, Through-Hole TO-92, and Surface Mount SOT-23, the 2N4391 is versatile for various board layouts. The TO-18 package is hermetically sealed and suitable for military applications. Gate leakages are typically less than 50pA at room temperature.
