2N3958 - Dual Matched N-Channel JFET

Download the 2N3958 datasheet PDF. This datasheet also covers the 2N3957 variant, as both devices belong to the same dual matched n-channel jfet family and are provided as variant models within a single manufacturer datasheet.

General Description

The -50V 2N3957 and 2N3958 matched pair JFET’s are targeted for high input impedance applications for mid to high frequency designs.

Gate leakages are typically 10pA at room temperatures.

Parts are matched down to 5mV.
