Carrier Tape Specification SO-8

The SMDBxx series of devices are designed to protect up to four

data lines. The devices are connected as follows:

✔

The SMDBxx are unidirectional 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. 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.
