Q1: What is the difference between a Schottky diode and a regular diode?
A1: A Schottky diode has a lower forward voltage drop than a regular diode, which makes it useful in applications where power dissipation is a concern. Schottky diodes also have a faster switching speed and lower reverse recovery time.
Q2: What is reverse recovery time?
A2: Reverse recovery time is the time it takes for a diode to switch from conducting in the forward direction to blocking in the reverse direction. This time delay can cause issues in high-frequency switching applications, which is why Schottky diodes are often used instead.
