SIDACtor Device
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.
* For surge ratings, see table below.
** I
T
is a free air rating; heat sink I
T
rating is 25 A.
General Notes:
All measurements are made at an ambient temperature of 25 C. I
PP
applies to -40 C through +85 C temperature range.
I
PP
is a repetitive surge rating and is guaranteed for the life of the product.
Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
V
DRM
is measured at I
DRM.
V
S
is measured at 100 V/s.
Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
Off-state capacitance (C
O
) is measured at 1 MHz with a 2 V bias and is a typical value.
