SIDACtor Device
This SIDACtor device is a 5000 A solid state protection device offered in a non-isolated
1
2 _{TO-218 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/µs.
• 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.
