This
Battrax
device is an integrated overvoltage protection solution for SLIC-based
(Subscriber Line Interface Circuit) line cards. This six-pin device is constructed using
four SCRs and four gate diodes.
The device is referenced to V
BAT
and conducts when a voltage that is more negative
than -V
REF
is applied to the cathode (pins 1, 3, 4, or 6) of the SCR. During conduction,
all negative transients are shorted to Ground. All positive transients are passed to
Ground by steering diodes.
For specific diagrams showing these
Battrax
applications, see Figure 3.37.

* For individual “UA” and “UC” surge ratings, see table below.
** Contact factory for release date.
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 (C
O
) is measured at 1 MHz with a 2 V bias and is a typical value. “UC” product is approximately 2x the listed
value.
• V
REF
maximum value for the negative Battrax is -200 V.
