Which of the following is disadvantage of fast recovery diodes?
Correct answer: C. Doping is carried out
- A. Recovery is only 5 µs
- B. Recovery is only 50 µs
- C. Doping is carried out
- D. None of these
Explanation
Fast recovery is obtained by lifetime-control techniques such as doping, but these introduce trade-offs including increased leakage current and reduced voltage capability. Hence doping is treated as the disadvantage listed here.
