Multiport SIDACtor Device
The multiport line protector is an integrated multichip solution for protecting multiple
twisted pair from overvoltage conditions. Based on a six-pin surface mount SOIC
package, it is equivalent to four discrete DO-214AA or two TO-220 packages. Available
in surge current ratings up to 500 A, the multiport line protector is ideal for densely
populated, high-speed line cards that cannot afford PCB inefficiencies or the use of
series power resistors.
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 individual “UA”, “UB”, and “UC” 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
, and V
S
is measured at 100 V/µs.
• Off-state capacitance (C
O
) is measured between Pins 1-2 and 3-2 at 1 MHz with a 2 V bias and is a typical value for “UA” product.
“UB” and “UC” capacitance is approximately 2x higher.
