Description : State any two applications of zener diode.
Answer : Applications of Zener Diode: i) As a voltage regulator. ii) As a fixed reference voltage provider in transistor biasing circuits. iii) As peak clippers or limiters in wave shaping circuits.
Description : List specification of zener diode
Answer : 1. Zener Voltage 2. Maximum Zener current 3. Power dissipation 4. Operating temperature 5. Dynamic Resistance
Description : Explain with circuit diagram operation of zener diode as a voltage regulator.
Answer : The function of a regulator is to provide a constant output voltage to a load connected in parallel with it in spite of the ripples in the supply voltage or the variation in the load ... V0 = VZ is obtained across RL, whenever the input voltage remains within a minimum and maximum voltage.
Description : When biased correctly, a zener diode:
Answer : When biased correctly, a zener diode: Has a constant voltage across it
