Answer: a Explanation: If a Zener diode of TC of about -2mV is connected with a forward diode (which has a TC of about +2mV) in series, the combination can be used to obtain a very low (close to zero) TC. 14. In Zener diode, for currents greater than the knee current, the v-i curve is almost a) Almost a straight line parallel to y-axis
Answer-7: Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage.
Follow-up question #2: would you classify the zener diode in this circuit as a series voltage regulator or a shunt voltage regulator? Explain your answer. Challenge question: at what point is the zener diode unable to regulate load voltage? Is there some critical load condition at which the diode ceases to regulate voltage?
The VI characteristics of a Zener diode are shown in the below figure. When forward-biased voltage is applied to the Zener diode, it works like a normal diode. When reverse-biased voltage is applied to a Zener diode, it allows only a small amount of leakage current until the voltage is less than Zener voltage (V z). As the reverse bias voltage ...
If the zener diode is shunted across the load R L and the voltage across zener diode is more than the zener voltage V Z then zener diode is on ‘on’ state , and any variation in voltage across the zener diode due to variations either in supply voltage or in load resistance is not able to change the output voltage. Thus zener diode maintains ...
