CATV and HFC SIDACtor Device CATV and HFC SIDACtor Device 1 3 This SIDACtor device is a 1000 A solid state protection device offered in a TO-220 package. It protects equipment located in the severe surge environment of Community Antenna TV (CATV) applications. Used in Hybrid Fiber Coax (HFC) applications, this device replaces the gas tube traditionally used for station protection, because a SIDACtor device has a much tighter voltage tolerance.

General Notes: • All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range. • IPP 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. • VDRM is measured at IDRM. • VS is measured at 100 V/µs. • Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request. • Off-state capacitance (CO) is measured at 1 MHz with a 2 V bias and is a typical value.
