Battrax Dual Positive/Negative SLIC Protector
Battrax Dual Positive/Negative SLIC Protector
(+VREF
)
This Battrax device protects Subscriber Line Interface Circuits (SLIC) that use both a
5
positive and negative Ring voltage. It limits transient voltages with rise times of 100 V/
µs to V
±10 V.

Teccor’s six-pin Battrax devices are constructed using four SCRs and four gate diodes.
The SCRs conduct when a voltage that is more negative than -V (and/or more
REF
positive than +V
) is applied to the cathode (Pins 1 and 3) of the SCR. During
REF
conduction, the SCRs appear as a low-resistive path which forces all transients to be
shorted to ground.
