SIDACtor® Device

TO-92 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 “EA”, “EB”, and “EC” surge ratings, see table below.

General Notes:

• Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
