Carrier Tape Specification SO-8

The SMDAxx series of devices are designed to protect up to four data

lines. The devices are connected as follows:

✔

The SMDAxx 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.
