Schottky Diode – Definition
A diode consists of MS junction (Metal-To-Semiconductor) rather than PN junction is called Schottky diode. It is used on high frequency as rectifier. Schottky diode is also called Hot-Carrier diode or Schottky Barrier diode. It has no depletion layer and lowest reverse recovery time. All the MCQs on Schottky Diode Questions and Answers are published according to the new study syllabus for the academic year 2021-22.
