This hybrid Single In-line Package (SIP) protects four twisted pairs from overcurrent and overvoltage conditions.

Comprised of twelve discrete DO-214AA SIDACtor devices and eight TeleLink surface mount fuses, it is ideal for densely populated line cards that cannot afford PCB inefficiencies or the use of series power resistors. Surge current ratings up to 500A are available.

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.
• Vs is measured at 100 V/µs.
• Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
• Off-state capacitance is measured between pins 2-3 and 3-4 at 1 MHz with a 2 V bias and is a typical value.
• Designed to meet balance requirements of GTS 8700 and GR 974.
