P0080SB
Bidirectional Overvoltage Protector
Revision:B
General Description
Dual symmetrical transient voltage suppressors
are solid state crowbar devices especially designed to
protect sensitive telecommunication equipment against
lighting strikes and other transient overvoltages.
Main Applications
T1/E1, ISDN, and xDSL transmission equipment
Customer Premises Equipment (CPE) such as
phones, modems, and caller ID adjunct boxes.
PBX’s and other switches
Primary protection including main distribution
frames, building entrance equipment and station
protection modules
Data lines and security systems
Features
Advantages of the dual symmetrical transient
voltage suppressors include their fast response time,
stable electrical characteristics, long term reliability,
and low capacitance. Also, because the devices are
crowbar devices, they can not be damaged by voltage
and they have extremely high surge current rating.
