Voltage Variable Capacitor Diode. Variable capacitance diode varicap diode also called varactor diode a special type of semiconductor diode. Pn junctions don t have a massive amount of capacitance hence you only get several tens of pf for something like a bb171 made by nxp.
Variable capacitance diodes have established a broad applications base from voltage controlled crystal oscillators vxco to television and cellular communications. Variable capacitance diode varicap diode also called varactor diode a special type of semiconductor diode. Cvdb 320 6n538 jennings 10 320pf 5kv variable vacuum capacitor.
While the threshold voltage is not breached the radio signal will pass through the diode as the diode acting as a capacitance connection component.
Symbol of varactor diode the symbol of the varactor diode is similar to that of the pn junction diode. Now we are talking. Varactors are used as voltage controlled capacitors. That substitute device is the voltage variable capacitance diode.
