Answer & Explanation
Correct AnswerD. Both Assertion and Reason are TRUE
Quick Explanation
A power MOSFET includes an intrinsic body diode connected anti-parallel to its controlled channel. The channel carries controlled current in its normal direction, while the body diode provides a reverse-current path; therefore the device structure can handle current in both directions, although controlled blocking/conduction capability is not symmetrical.
Formula / Key Relation
Power MOSFET = controlled MOS channel + intrinsic anti-parallel body diode
Detailed Explanation
Correct Answer
D — Both Assertion and Reason are TRUE
Concept and Reasoning
A power MOSFET includes an intrinsic body diode connected anti-parallel to its controlled channel. The channel carries controlled current in its normal direction, while the body diode provides a reverse-current path; therefore the device structure can handle current in both directions, although controlled blocking/conduction capability is not symmetrical.
Calculation / Key Relation
Power MOSFET = controlled MOS channel + intrinsic anti-parallel body diode
Exam Takeaway
Remember: MOSFET body diode provides the reverse-current path.
Common Mistake
Do not interpret “bidirectional current path” as bidirectional voltage-blocking capability.
Quick Trick
Remember: MOSFET body diode provides the reverse-current path.
Common Mistake
Do not interpret “bidirectional current path” as bidirectional voltage-blocking capability.
Exam Tip
