2.4. VI Characteristics of PN Junction Diode

Try these first

1. 1.

   What happens when a PN junction diode is forward biased?

   Hint

   Think about the direction of the current flow.

2. 2.

   What is the threshold voltage for a silicon diode?

   Hint

   Recall the typical value for silicon across various sources.

3. 3.

   What is the threshold voltage for a silicon diode?

   • 0.3 V
   • 0.5 V
   • 0.7 V

   Hint

   Refer back to typical values discussed in the lesson.

4. 4.

   In reverse bias, when does current significantly increase?

   • True
   • False

   Hint

   Think about how breakdown voltage impacts current flow.

5. 5.

   Design a circuit involving a silicon PN junction diode. Explain the expected current behavior under both forward and reverse bias conditions.

   Hint

   Consider both bias conditions and how to apply voltage.

6. 6.

   Given a graph of current vs. voltage for a diode, identify and explain key features including threshold and breakdown voltages.

   Hint

   Use key points highlighted in the lesson on diode characteristics.
