VCR3P

VCR2N, VCR4N, VCR7N, VCR3P JFET Voltage Controlled Resistors ~Siliconix ~ incorporated The VCR2N, VCR4N, VCR7N, and VCR3P line of JFET voltage controlled resistors utilize the JFET's linear output characteristics in the resistive region. This area of operation is around VDS = 0 V and extends for a range up to several hundred millivolts - up to the point ID begins to saturate. Key to device performance is the predictable rDS change versus VGS bias where: . rDS (@ VGs= 0) I Ir DS bias "" 1 _ VGS VGS(OFF) This series features three n-channel devices with rDS(ON) ranging from 20 - 8000 il. Also featured is a p-channel device with rDS(ON) specified between 70 and 200 il. All packages are hermetically sealed and may be processed per MIL-S-19500. (See Section 1.)
