Application example ESD24VS2U ( uni-directional )
12V / 24V DC power supply line protection
The protection diode should be placed very
close to the location where the ESD or other
transients can occur to keep loops and
inductances as small as possible. Pin 3
should be connected directly to a ground
plane on the board.
