Device connections

1.

Connect pins 2, 3, 6 and 7 to Ground to guarantee a good surge current capability for

long duration disturbances.

2.

To take advantage of the" 4-point“ structure of the THBT, 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.
