SIDACtor Devices
Two-chip SIDACtor® Device
The two-chip SIDACtor design provides a through-hole technology protection solution. It is
intended for telecom applications that do not require a balanced solution. For primary
protection applications, devices with higher holding current and integrated failsafe options
are available.
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 “AA”, “AB”, and “AC” surge ratings, see table below.
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.
