Four-port Longitudinal Two-chip Protector
Four-port Longitudinal Two-chip Protector
This hybrid Single In-line Package (SIP) protects four twisted pairs from overcurrent and
overvoltage conditions. Comprised of eight 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 500 A
are available.

General Notes:
•
•
•
•

•
•
All measurements are made at an ambient temperature of 25 °C. I applies to -40 °C through +85 °C temperature range.
PP
PP
Listed SIDACtor devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities.
I
is a repetitive surge rating and is guaranteed for the life of the product.
V
V
is measured at I
DRM.
DRM
is measured at 100 V/µs.
S
Special voltage (V and V
) and holding current (I ) requirements are available upon request.
H
S
DRM
Off-state capacitance (C ) is measured between Pins 4-3 and Pins 2-3 at 1 MHz with a 2 V bias and is a typical value for “ZA”
O
product. “ZB” and “ZC” capacitance is approximately 2x higher.
•

Device is designed to meet balance requirements of GTS 8700 and GR 974.
Lower capacitance MC versions may be available. Contact factory for further information.
