WebTo use this online calculator for Reverse Recovery Current, enter Reverse Recovery Charge (QRR) & Change in Current (ΔI) and hit the calculate button. Here is how the Reverse Recovery Current calculation can be explained with given input values -> 35.49648 = sqrt (2*0.042*0.015). WebJul 29, 2024 · At a high level if you take an NPN BJT transistor for example, P region is the base of the transistor. The transistors P region is much lightly doped than the N region. Since the N region is heavily doped the there is more current flowing from N to P region.
