Question 1 of 10
Which type of diode's capacitance varies with the applied reverse voltage?
Varactor diodes, also known as varicap or volt cap diodes, are designed with a junction capacitance that changes with the reverse voltage applied.
Question 2 of 10
What is another name for a Varactor diode?
Varactor diodes are also referred to as Vari Cap or Volt Cap diodes.
Question 3 of 10
What is a key characteristic of a Tunnel Diode?
Tunnel diodes are characterized by high impurity concentration which leads to a narrow depletion region, facilitating tunneling.
Question 4 of 10
What is another name for a Tunnel Diode?
Tunnel diodes are also known as Esaki diodes.
Question 5 of 10
Which of the following is NOT an application of a Varactor diode?
High-speed switching is more related to Tunnel Diode applications. Varactor diodes are used in frequency control and related applications.
Question 6 of 10
What type of junction does a Schottky diode utilize?
Schottky diodes use a metal-semiconductor junction instead of a PN junction.
Question 7 of 10
What is a major advantage of Schottky diodes?
Schottky diodes have a low forward voltage drop, a key advantage.
Question 8 of 10
Which materials are commonly used in Schottky diodes to form the metal-semiconductor junction?
Metals like gold, silver, platinum, or tungsten are used in the metal-semiconductor junction.
Question 9 of 10
Which of the following is NOT an advantage of a Schottky Diode?
Schottky diodes, being unipolar devices, do not have reverse currents, not 'with reverse currents'
Question 10 of 10
Which of the following is an application of a Schottky Diode?
Schottky diodes are often used in power rectifier circuits.
