The reverse recovery time of diode is trr = 3 μs and the rate off all of the diode current is di/dt = 30 A/μs. The storage charge current QRR is___________?
Correct answer: B. 135 μs
- A. 130 μs
- B. 135 μs
- C. 140 μs
- D. 145 μs
Explanation
Using the triangular reverse-recovery-current approximation, QRR = ½(di/dt)tRR² = ½(30)(3²) = 135 μC. The options show a corrupted unit, since charge should be expressed in coulombs, not microseconds.
