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 VBAT and conducts when a voltage that is more negative
than -VREF 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 the diodes.

* “L” in part number indicates RoHS compliance. For non-RoHS compliant device, delete “L” from part number.
For individual “UA” and “UC” surge ratings, see table below.
General Notes:
• All measurements are made at an ambient temperature of 25 °C. IPP applies to -40 °C through +85 °C temperature range.
• IPP is a repetitive surge rating and is guaranteed for the life of the product.
• IPP ratings assume a VREF = ±48 V.
• VDRM is measured at IDRM.
• VS is measured at 100 V/µs.
• VREF maximum value for the negative Battrax is -200 V.
