Battrax
Dual Positive/Negative SLIC Protector
This
Battrax
device protects Subscriber Line Interface Circuits (SLIC) that use both a
positive and negative Ring voltage. It limits transient voltages with rise times of 100 V/
μs to V
REF
±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
REF
(and/or more
positive than +V
REF
) is applied to the cathode (Pins 1 and 3) of the SCR. During
conduction, the SCRs appear as a low-resistive path which forces all transients to be
shorted to ground.
For a diagram of a
Battrax
application, see Figure 3.30.
* For individual “UA” and “UC” surge ratings, see table below.
General Notes:
All measurements are made at an ambient temperature of 25 °C. I
PP
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.
I
PP
ratings assume a V
REF
= ±48 V.
V
DRM
is measured at I
DRM.
V
S
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.
V
REF
maximum value for the negative Battrax is -200 V.
V
REF
maximum value for the positive Battrax is 110 V.
