Hello,
The DA2JF8100L diode datasheet says that its IFSM parameter is just 1A.
In our circuit, this diode would experience a current of 90A for just 2us. This is due to a capacitor getting charged through this diode when the mains comes on at mains peak.
(as in the attached LTspice simulation and the jpeg schematic)
Is this current peak OK? After all, it only lasts for 2us and isn’t going to overheat the diode?
