LCAS Asymmetrical Multiport Device
This 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
line cards that cannot afford PCB inefficiencies or the use of series power resistors.
For a diagram of an LCAS (Line Circuit Access Switch) application, see Figure 3.21.
* 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.
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 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.
