*Question T6B06:
How is the cathode lead of a semiconductor diode often marked on the package?*  

*Correct Answer is  B: With a stripe*  

### AI Response: (may contain errors)  

The correct answer to how the cathode lead of a semiconductor diode is often marked on the package is:

**B: With a stripe**

### Explanation:

1. **Why the correct answer is correct:**
   - Diodes are polarized components, meaning they have a specific direction for current flow. The cathode is the terminal where current exits the diode. To help identify this terminal, manufacturers typically mark the cathode lead with a stripe or band on the diode package. This visual cue helps prevent incorrect connections in circuits.

2. **Why the other choices are incorrect:**
   - **A: With the word "cathode"**: While some diodes may have markings, it is uncommon for the word "cathode" to be printed on the package. The stripe is the standard marking.
   - **C: With the letter C**: The letter "C" is not a standard marking for identifying the cathode. Diode packages do not typically use letters for this purpose.
   - **D: With the letter K**: Similar to option C, the letter "K" is not used to denote the cathode in diode packages. The stripe is the recognized method.

### Useful Rules of Thumb:
- Always check the diode's datasheet for specific markings, as there can be variations among manufacturers.
- Remember that the anode is the positive side, and the cathode is the negative side, which is crucial for proper circuit function.

This understanding will help you identify diodes correctly in your projects and during the exam.
