1. Connect pins 2, 3, 6 and 7 to

ground in order to guarantee a

good surge current capability for

long duration disturbances.

2. To take advantage of the

“4-point” structure of the

TPIxxxN, the Tip and Ring lines

have to cross the device. In this

case, the device will eliminate the

overvoltages generated by the

parasitic inductances of the

wiring (LdI/dt), especially for very

fast transients.
