SIDACtor® Device
DO-214AA SIDACtor solid state protection devices protect telecommunications equipment
such as modems, line cards, and CPE (telephones, answering machines, and fax
machines).
SIDACtor devices enable equipment to comply with various regulatory requirements
including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A
(formerly known as FCC Part 68).
* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.
For individual “SA”, “SB”, and “SC” 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/µs.
• Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request.
