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.

All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range.
I
PP is a repetitive surge rating and is guaranteed for the life of the product.
PP ratings assume a VREF = ±48 V.
I

DRM is measured at IDRM.
VS is measured at 100 V/µs.
Off-state capacitance is measured at 1 MHz with a 2 V bias and is a typical value. “UC” product is approximately 2x the listed value.
Positive Battrax information is preliminary data.

REF maximum value for the negative Battrax is -200 V.
REF maximum value for the positive Battrax is 110 V.
