Multiport MicroCapacitance (MC)
SIDACtor Device
The multiport MC line protector is an integrated, multichip solution for protecting
multiple twisted pair from overvoltage conditions. It is intended for applications
sensitive to load values. Typically, high speed connections require lower capacitance.
C
O
values for the MC devices are 40% lower than standard UC devices
Based on a six-pin surface mount SOIC package, it is equivalent to four discrete DO-
214AA or two TO-220 packages, which makes it ideal for densely populated, high-
speed line cards that cannot afford PCB inefficiencies or the use of series power
resistors. Surge current ratings up to 500 A are available.
SIDACtor devices are used to enable equipment to meet 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 100 V/s.
Special voltage (V
S
and V
DRM
) and holding current (I
H
) requirements are available upon request.
Off-state capacitance (C
O
) is measured at 1 MHz with a 2 V bias.
