Battrax® Single Port Negative SLIC Protector

This programmable Battrax device is referenced to a negative voltage source. This

dual-chip package includes internal diodes for transient protection from positive surge

events.

For a diagram of a Battrax application, see Figure 6.47 in Section 6, “Reference

Designs” of this Telecom Design Guide.

* “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 B1101, B1161, and/or B1201 is -200 V.
