2N3822 - N-Channel JFET

Download the 2N3822 datasheet PDF. This datasheet also covers the 2N3821 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 -50V InterFET 2N3821 and 2N3822 are targeted for sensitive amplifier stages for VHF designs.

Gate leakages are typically less than 10pA at room temperatures.

The TO-72 package is hermetically sealed and suitable for military applications.

Key Features

  • InterFET N0032H Geometry.
  • Typical Noise: 7 nV/√Hz.
  • Low Ciss: 6.0pF Typical.
  • RoHS Compliant.
  • SMT, TH, and Bare Die Package options.
