I would like to calculate a switching power loss of BY203-20S diode, in following conditions:
Vr = 1600 V, fsw = 65 kHz
Switching loss of a diode is given by equation:
\$Psw = Vr*fsw*Qrr\$
We can substitute for the reverese recovery charge:
\$Qrr = (Trr*Irrm)/2\$
However, value of Qrr nor Irrm is given in the datasheet of BY203-20S, only value Trr = 300 ns is given.
If I choose arbitrary value of 1 A for Irrm, switching loss yields in huge value of about 15.6 W, which of course the tiny package can't handle.
Is there some way to estimate the Irrm or Qrr to calculate the switching loss more accurately?
