F Series 5-Pin Solid-State Overcurrent Surge Protectors
Bourns® solid-state 5-pin protector modules are designed to protect personnel and equipment from damage caused by excessive
voltages and currents induced on telephone lines by lightning and AC power system faults. The solid-state protectors incorporate a
fast semiconductor switch with operating voltage nearly independent of transient rise time. The module’s fast, repeatable operation is
designed to protect excellent equipment protection and long protection life. A fail-short mechanism operates under high current power-cross conditions to permanently short the line to ground. Heat coils provide overcurrent (sneak current) protection in 4 ohm and
20 ohm versions. The industry-standard 5-pin base makes the modules interchangeable with existing 5-pin modules. The pins are
available with gold or tin plating. The protectors have a detent position which disconnects the equipment side but leaves the module
connected to the line side. Test points on the line side are optional.
Bourns® 5-pin protectors are used in many Central Office applications. These modules are a superior choice for 5-pin protection of
copper pair circuits.
