May 17 at 5:33 | comment | added | qrk | Those ferrite beads with the input capacitance will form a resonant circuit that can create high voltage peaks with step-currents. I've been affected by this in the past. | |
May 17 at 2:48 | comment | added | Tim Williams | Or a single unidirectional TVS can be used -- note that schottky have comparable voltage drop under surge conditions to PN diodes, so it doesn't really matter. If tighter clamping is required, I would suggest an active circuit, though this does get challenging to implement for short transients. (All the same, few things are that sensitive, to moderate reversal for short durations, so it doesn't come up often.) | |
