T10C SIDACtor® Device RoHS (T) 2 (G) 3 (R) 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 TIA968-A (formerly known as FCC Part 68). For primary protection applications, integrated failsafe options are available.

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. 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 across Pins 1-2 / 3-2. • VS is measured at 0.5 V/µs across Pins 1-2 / 3-2. • Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request.
