SIDACtor Devices
T10C SIDACtor® Device
The bi-directional T10C devices are a through-hole technology SIDACtor protector. It is
intended for cost-sensitive telecommunication applications. The three-terminal configuration
matches G.D.T. pin configuration; for plug-in applications, the T10C fits in the KRONE™
three-point connector block (5B).
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 primary protection applications, integrated failsafe options are available.
* For failsafe option, add “F” at end of part number. See Section 9, “Mechanical Data” for mechanical view of failsafe option.
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
across Pins 1-2 / 3-2.
• V
S
is measured at 0.5 V/µs across Pins 1-2 / 3-2.
• Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
