As you see in the circuit diagram we are giving 9V to the 7805IC and getting regulated +5V at the output. The capacitors C1 and C2 are used for filtration. Zener Voltage Regulator Circuit . Here, we ...

Using this simple Zener value evaluator circuit and a known-value zener diode, you can find the breakdown voltage value of any zener diode. The circuit is divided into two sections: zener evaluator ...

The tester can also identify the polarity of zener diodes. Zener Diode Tester Circuit. The power supply section comprising transformer X1, rectifier diode D1, filter capacitor C1, resistor R1, ...

We will always receive an output voltage less than or equal to the rating of the Zener diode. 2. Overvoltage Protection Circuit using Zener Diode: In the second method of overvoltage protection, ...

Zener diodes as regulators. The previous experience has made us understand that if a Zener diode inversely polarized goes to conduction, there is a fixed voltage, Vz, on it. For example, if there is ...

This is obviously only possible if the stabilised voltage is higher than the zener voltage. Circuit diagram: It therefore has to be amplified a little. This is exactly what this circuit does: it ...
