VCR7N JFET Voltage-Controlled Resistors

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. This series of junction FETs is intended for applications where the drain-source vo.
