| 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. Electrical Parameters Part Number * P1400AD P1800AD VDRM Volts 120 170 VS Volts 160 220 VT Volts 3 3 IDRM Amps 5 5 IS mAmps 800 800 IT Amps 2.2 2.2 IH mAmps 50 50 CO pF Pins 1-3 200 150 * For surge ratings, see table below. 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/s. * 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.
