Carrier Tape Specification SO-8

The SMDBxxC series of devices are designed to protect up to

four data lines. The devices are connected as follows:

✔

The SMDBxxC are bidirectional devices and are designed for

use on line where the normal operating voltage is above

ground. Pins 1, 2, 3, and 4 are connected to the protected

lines. Pins 5, 6, 7, and 8 are connected to ground. Since the

device is electrically symmetrical, these connections may be

reversed. The ground connections should be made directly to

the ground plane for best results. The path length is kept as

short as possible to reduce the effects of parasitic inductance

in the board traces.
