When a reverse voltage is applied to a PN junction of varactor diode, the holes in the p-region are attracted to the anode terminal and electrons in n-region are attracted to the cathode terminal of varactor diode, creating a region where there is little charge of either type(the depletion region). This region, the depletion region, is essentially devoid of carriers and behaves as the dielectric of a capacitor. The P and N regions behave as the Capacitors Plates.
Specifications of Varactor Diode
Major varactor diode considerations are:
- Capacitance value
- Reverse voltage
- Variation in capacitance with voltage
- Maximum reverse working voltage
- Leakage current
