IRD3903 Overview
Reverse voltage 400V is a reasonable value.For this device, the average rectified current is 20A volts.In this case, forward current can reach 20A.As you can see, the fuse's current rating is 20A, which means that it can carry a maximum current for an indefinite period without losing too much performance.Phase diode rectifier is possible to use a surge current of maximum value 355A.Based on the data chart, the peak reverse is 50μA.
IRD3903 Features
an average rectified current of 20A volts
a current rating of 20A
the peak reverse is 50μA
