Zener Diode Clamping Voltage. A typical zener diode for general electronic circuits is the 500mw bzx55 series or the larger 1 3w bzx85 series were the zener voltage is given as for example c7v5 for a 7 5v diode giving a diode reference number of bzx55c7v5. The conduction of the transistor q1 is dependent on the base emitter voltage of the transistor.

The easiest way to determine the true clamping voltage of a diode when exposed to an iec esd strike is to look at the transmission line pulse tlp response curve. Zener diode clipping circuitstopics covered 1. The following easy steps can be used to calculate the resistor required.
So the threshold value over which the circuit does not conduct is approximately 5 1v.
Zener diode as a voltage clamper in a circuit involving the ac input source different from the normal pn diode clamping circuit a zener diode can also be used. A typical zener diode for general electronic circuits is the 500mw bzx55 series or the larger 1 3w bzx85 series were the zener voltage is given as for example c7v5 for a 7 5v diode giving a diode reference number of bzx55c7v5. If you have a voltage that swings between 7 v and 7 v you could use a single 4 v zener connected to ground to ensure that the signal does not exceed 4 v or go below 0 7 v where the diode conducts forward to ground. Calculate the difference in voltage across the series resistor 12 5 1 6 9 volts.
