Chapter 58, Problem 1RQ
How is a zener diode connected in a circuit as compared to a common junction diode?
Expert Solution & Answer
To determine
The way in which the zener diode is connected in the circuit as compared to the junction diode.
Explanation of Solution
The PN junction is commonly known as the diode. The diode the electronic device that acts as a swtich and conducts in one direction only.
To forward bias the diode the P terminal is connected to the ANODE and the N type is connected to the cathode. Reverse of this is done to reverse bias the diode.
The symbol for the diode is shown below.
The diode operates like a swtich, when the diode is forward biased the current flows through it in one direction only that is from P terminal to N terminal. To reverse the diode the cathode is connected to P and anode to N, for ideal condition the diode do not conduct in reverse but there is a small amount of current through it that is called the leakage current.
The zener diode is the diode that can operate in the reverse biased and the region of operation in that case is called the zener region. The diode conducts when the diodes breaks down in the reverse direction known as avalanche.
Therefore, the zener diode is connected in the circuit in reverse polarity as compared to common junction diode.
