InterFET

Download the 2N4861 datasheet PDF. This datasheet also covers the 2N4856 variant, as both devices belong to the same n-channel jfet family and are provided as variant models within a single manufacturer datasheet.

General Description

The -40V InterFET 2N4856/A, 2N4857/A, and 2N4858/A JFET’s are targeted for very low noise switching applications for mid to high frequency designs.

Gate leakages are typically 50pA at room temperatures.

The TO-18 package is hermetically sealed and suitable for military applications.

Key Features

InterFET N0132S Geometry.
Low Noise: 1.2 nV/√Hz Typical.
Fast Switching.
RoHS Compliant.
SMT, TH, and Bare Die Package options.
