Protection against Overvoltages and Reverse Currents
Protection Requirements
According to the absolute maximum ratings of the IEPC, the PEB 2025 has to be protected against
overvoltage spikes comming in on aFi. This is done by the diodes D1 and D2 in figure 8. In some
applications it could be necessary to protect the IEPC output aFi against reverse by using diode D3.
