SIDACtor Devices
T10A SIDACtor® Device
The bi-directional T10A devices are a through-hole technology SIDACtor protector. It is
intended for cost-sensitive telecommunication applications. This T10 SIDACtor series
enables 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).
* For 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 0.5 V/µs.
• Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
