*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 Figure E6-2, the schematic symbol for a Schottky diode is represented by choice B: 6.

### Explanation:

1. **Why the correct answer is correct:**
   - **Schottky Diode Symbol:** The Schottky diode is characterized by a symbol that looks similar to a regular diode but with an "S" shape or a bent line on the cathode side. This unique feature distinguishes it from other types of diodes. In Figure E6-2, symbol 6 includes this characteristic, making it the correct choice for a Schottky diode.

2. **Why the other choices are incorrect:**
   - **Choice A: 1** - This symbol typically represents a standard diode, which lacks the distinctive bent line of a Schottky diode.
   - **Choice C: 2** - This symbol is often used for a Zener diode, which has a different configuration with a bent line on both sides of the diode symbol.
   - **Choice D: 3** - This symbol is usually for a light-emitting diode (LED), which includes arrows indicating light emission, not present in a Schottky diode symbol.

3. **Useful Information:**
   - **Schottky Diode Characteristics:** Schottky diodes are known for their low forward voltage drop and fast switching speed, making them useful in high-frequency applications.
   - **Symbol Recognition:** Recognizing the unique symbol of a Schottky diode is crucial for identifying it in circuit diagrams and understanding its role in the circuit.

By understanding these distinctions, you can accurately identify the Schottky diode symbol in schematic diagrams.
