Zener Diode Clamping Circuit. Zener voltage regulator circuit this is one of the two configurations of overvoltage protection circuits using zener diode. For a clamping circuit at least three components a diode a capacitor and a resistor are required.
I the shape of the waveform will be the same but its level is shifted either upward or downward. Diode clipper circuits are also called limiters because they limit or clip off the positive or negative part of an input ac signal as zener clipper circuits limit or cut off part of the. There are many circuits that use zener diodes ranging from very simple zener diode circuits up to far more complicated ones.
Note the polarity marked on the capacitor in figure a below.
There are many circuits that use zener diodes ranging from very simple zener diode circuits up to far more complicated ones. Diode clipper circuits are also called limiters because they limit or clip off the positive or negative part of an input ac signal as zener clipper circuits limit or cut off part of the. The important points regarding clamping circuits are. The zener diode is acting like a biased diode clipping circuit with the bias voltage being equal to the zener breakdown voltage.
