Question:
Turn-off of an SCR, it is necessary to reduce its current to less than
Turn-off of an SCR, it is necessary to reduce its current to less than
Show Hint
SCR turns OFF only when current < holding current.
Updated On: Jul 2, 2026
- Trigger current
- Holding current
- Breakdown current
- Forward current
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
SCR remains ON even after gate signal is removed.
Step 1: Holding current Minimum current required to keep SCR in ON state.
Step 2: Turn-off condition Current must fall below holding current.
Step 3: Trigger current Required only for turning ON.
Step 4: Breakdown current Not relevant for normal operation.
Step 5: Conclusion \[ \boxed{\text{Holding current}} \]
Final Answer: \[ \boxed{(B)} \]
