F Series 5-Pin Solid-State Overvoltage 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 provide 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. The industry-standard 5-pin base makes the modules interchange-
able 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.
