This datasheet also covers the IFNU421 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 -40V InterFET IFNU421, IFNU422, and IFNU423 JFET’s are targeted for ultra high input impedance applications for differential amplification and impedance matching.
Gate leakages are less than 1pA at room temperatures.
