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. This series of junction
FETs is intended for applications where the drain-source
voltage is a low-level ac signal with no dc component.
Key to device performance is the predictable rDS change
versus VGS bias where:
Ť ŤrDS(@ VGS + 0)
rDSbias [
VGS
1– VGS(off)
These n-channel devices feature rDS(on) ranging from 20 to
8000 W. All packages are hermetically sealed and may be
processed per MIL-S-19500 (see Military Information).
