This
SIDACtor
device is a 3000 A solid state protection device offered in a non-isolated
TO-263 (D
2
) package. It protects equipment located in the severe surge environment of
CATV (Community Antenna TV) applications.
In CATV line amplifiers and power inserters, this device can replace the gas tubes
traditionally used for station protection because
SIDACtor
devices have much tighter
voltage tolerances.

General Notes:
鈥?All measurements are made at an ambient temperature of 25 擄C. I

applies to -40 擄C through +85 擄C temperature range.
鈥?I
PP
is a repetitive surge rating and is guaranteed for the life of the product.
鈥?Listed
SIDACtor
devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
鈥?V
