PRODUCT WIDER APPLICATION

T3, E3, DS3 port protection

 

Design Notes:
Protection application:
T3 / E3 / DS3 line is a centralized digital telephone line with a bit rate of up to 45 Mbps and a low data signal voltage (~ 5V).
Solution description:
Two solutions are shown. The picture above is a GR-1089 outdoor solution that uses a resettable fuse, a semi-conducting discharge tube, and two MURS163T diodes (ON Semiconductor). The figure below is a GR-1090 indoor solution using a resettable fuse and a semi-conducting discharge tube device.
Supporting solutions:
For special designs, semi-conducting discharge tube devices with other voltages are available.
Regulatory issues:
This solution is designed to meet Telcordia GR-1089 standards.

Features:
Ruilongyuan is the only supplier that can provide low capacitance P0642SA device.
Application warning: Not applicable.
