VARACTORA diode that behaves like a variable capacitor, with the PN junction functioning like the
dielectric and the plates of a common capacitor.
VOLTAGE GAINRatio of voltage across a specified load.
VOLTAGE MULTIPLIERSMethods of increasing voltages used primarily where low current is
ZENER DIODEA PN-junction diode designed to operate in the reverse-bias breakdown region.
ZENER EFFECTA reverse breakdown effect in diodes in which breakdown occurs at reverse
voltages below 5 volts. The presence of a high energy field at the junction of a semiconductor
produces the breakdown.
