.As compared to a p-n junction device of equal rating, the Schottky diode has
Answer: a Explanation: Low reverse voltage rating is the only drawback against a p-n junction diode.
Answer: a
See lessExplanation: Low reverse voltage rating is the only drawback against a p-n junction
diode.
If the doping levels of the semiconductor is increased, then the width of the depletion layer
Answer: b Explanation: Higher the doping, more the number of charge carrier available to neutralize the opposite charges on the junction.
Answer: b
See lessExplanation: Higher the doping, more the number of charge carrier available to
neutralize the opposite charges on the junction.

Ideally the voltage drop across a conducting diode must be
Answer: b Explanation: Ideal conduction = No losses.
Answer: b
See lessExplanation: Ideal conduction = No losses.
A Schottky diode can be switchd off much faster than an equivalent p-n junction diode due to its
Answer: b Explanation: Due to the metal-silicon junction there are no stored charges, hence no reverse recovery time due to which the switching is faster.
Answer: b
See lessExplanation: Due to the metal-silicon junction there are no stored charges, hence no
reverse recovery time due to which the switching is faster.

Answer: b Explanation: Schottky diode uses a Al-Semiconductor junction.
Answer: b
See lessExplanation: Schottky diode uses a Al-Semiconductor junction.
In a Schottky diode, the silcon is usually
Answer: a Explanation: Usually only n-type silicon is used because the p-type has certain limitations.
Answer: a
See lessExplanation: Usually only n-type silicon is used because the p-type has certain
limitations.
Which of the following are/is the majority charge carriers in a Schottky diode?
Answer: b Explanation: The metal has no holes hence major(almost full) current flows due to the electrons only.
Answer: b
See lessExplanation: The metal has no holes hence major(almost full) current flows due to the
electrons only.
