DESCRIPTION
This device is dedicated to the protection of the
+5V power supply line against transient overvol-
tages due to surge of power rails up to the activa-
tion of the serial thermal protection element. It is
also dedicated to the protection of the +12V rail
against transient overvoltages.
note: The element in series with the 5V line is a resettable device, like Raychem Polyswitch MiniSMD075.
