IFNU423 - Dual Matched N-Channel JFET

Download the IFNU423 datasheet PDF. 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.

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.

Features

  • InterFET N0001H Geometry.
  • Low Leakage: 0.25 pA Typical.
  • Low Input Capacitance: 2.0 pF Typical.
  • High Input Impedance.
  • Replacement for U421, U422, U423.
  • RoHS Compliant.
  • SMT, TH, and Bare Die Package options.
