In the circuit shown below, transistor Q is turned off at t = 0. The transistor turns off with its current falling to zero instantly. Diode Ds is ideal. The freewheeling diode Df does not turn on until the capacitor voltage reaches Vs).
The value of capacitor Cs (in μs) so that the maximum \(\frac{dv}{dt}\) across the transistor is 100 V/μs is
Enter numerical value using the virtual keypad. Round off where necessary.
