Question
In Figure E6-2, which is the schematic symbol for a Schottky diode?
Answer Options
- A) 1
- B) 6
- C) 2
- D) 3
Correct Answer: B
Explanation
Figure E6-2 displays common schematic symbols for various types of diodes and related components. The Schottky diode (also known as a hot-carrier diode) has a distinct symbol that visually represents its metal-semiconductor junction, differentiating it from a standard junction diode or a Zener diode.
Symbol 6 represents the Schottky diode. It has the standard anode (triangle) and cathode (bar) structure, but the bar at the cathode terminal is replaced with a curved or S-shaped line, distinguishing it from the straight bar used for the standard rectifier diode (Symbol 4) and the Zener diode (Symbol 3).
