All ISRO Electronics & Communication (ECE) papers | ISRO Electronics & Communication (ECE) 2013

Topic: Analog Circuits

A Zener diode, when used in voltage stabilization circuits, is biased in

  • A. reverse bias region below the breakdown voltage
  • B. reverse breakdown region
  • C. forward bias region
  • D. forward bias constant current mode

Answer: B. reverse breakdown region

Explanation: The diode in the reverse biased region above breakdown voltage will regulate the load voltage against variations in load current and against the variations in supply voltage.
