Q4. What is the basic criteria of selecting a TVS diode.
Ans. 
The basic criteria for selecting a TVS diode is its breakdown voltage, power handling capability, and response time.
• The breakdown voltage should be higher than the maximum voltage that the circuit will experience.

• The power handling capability should be sufficient to handle the maximum transient power.

• The response time should be fast enough to clamp the transient voltage before it can damage the circuit.

Q5. Explain the difference between BJT and MOSFET. What is a avalanche breakdown?
Ans. 
BJT and MOSFET are two types of transistors. Avalanche breakdown is a phenomenon that occurs in both.
• BJT is a bipolar junction transistor that uses both electrons and holes for conduction while MOSFET is a metal-oxide-semiconductor field-effect transistor that uses only electrons.

• BJT has a higher gain and faster switching speed than MOSFET but is less efficient and generates more heat.

• Avalanche breakdown is a phenomeno...read more
