Part C. Zener Diode 1. 2. 4. Find a datasheet for a 1N749A Zener Diode. Record the value for reverse breakdown voltage below: 1N749A Reverse Breakdown voltage_ Build the circuit shown in Figure 3 in multisim. Include a voltmeter to measure the voltage across the Diode with the polarity reference shown and an ammeter to measure the current with direction as shown. (Note: for easy wiring, you can right-click on the meters in your circuit, and flip them horizontally.) Operate the supply voltage (Vsupply) between ± 20 V in steps of 1 V (i.e., -20 V, -19 V, -18 V, etc.) and place your results in Table 3 5. Plot the I-V characteristics of the diode using the data from Table 5 of the Lab Report. You should either do a **CLEAR** plot by hand or use a program like EXCEL and paste the results in the space provided V supply 1 ΚΩ www ww Current 1N749A * 510 2 ΚΩ Voltage + Figure 3: Third Circuit Using a Zener Diode 200 Ω
