RMS current ratings of a diode

The waveforms of the current flowing through a diode are shown in the figure below. Determine the RMS current ratings of the diode.


Solution Preview

In this problem, you have not mentioned how the current varies between t1 and t2. I'm assuming it to be sinusoidal variation.

square sum of current (SSC)= integration (t=0 to T) [i^2*dt]
here, T = 5 ms = 5000 micro sec

SSC = 150^2*(t1-0) + integration(t1 to ...
