*Question E6B10:
In Figure E6-2, which is the schematic symbol for a Schottky diode?*  

*Correct Answer is  B: 6*  

### AI Response: (may contain errors)  

In the context of the Extra Class exam, let's break down the question regarding the schematic symbol for a Schottky diode.

### Correct Answer: 6

- **Why the correct answer is correct:**
  - The Schottky diode is represented by a specific schematic symbol that includes a diode symbol with a distinctive "S" shape or a line that indicates the metal-semiconductor junction. In Figure E6-2, option 6 corresponds to this unique representation, making it the correct choice.

### Why the other choices are incorrect:

- **Choice A: 1**
  - This symbol typically represents a standard diode, which does not have the characteristics of a Schottky diode. Standard diodes have a simple triangle pointing to a line.

- **Choice B: 6**
  - This is actually the correct answer, so it cannot be incorrect.

- **Choice C: 2**
  - This symbol may represent another type of diode, such as a Zener diode or a different semiconductor device, which does not match the Schottky diode's characteristics.

- **Choice D: 3**
  - This symbol is likely used for a different electronic component, such as a light-emitting diode (LED) or a different type of rectifier, and does not represent a Schottky diode.

### Summary:
- The Schottky diode is characterized by its unique symbol, which is option 6 in Figure E6-2. Understanding the differences in diode symbols is crucial for identifying components in circuit diagrams. 

### Useful Tip:
- Familiarize yourself with common diode symbols and their characteristics, as this knowledge is essential for interpreting circuit diagrams effectively.
