VCR2N - JFET Voltage-Controlled Resistors

Download the VCR2N datasheet PDF. This datasheet also covers the VCR variant, as both devices belong to the same jfet voltage-controlled resistors family and are provided as variant models within a single manufacturer datasheet.

General Description

The VCR2N/4N/7N JFET voltage controlled resistors have an ac drain-source resistance that is controlled by a dc bias voltage (VGS) applied to their high impedance gate terminal.

Minimum rDS occurs when VGS = 0 V.

As VGS approaches the pinch-off voltage, rDS rapidly increases.

Key Features

  • D Continuous Voltage-Controlled Resistance D High Off-Isolation D High Input Impedance.
