Battrax® Single Port Positive/Negative SLIC Protector

This six-pin surface mount package contains programmable protection devices for

both negative and positive voltage references.

It is constructed using four SCRs and four gate diodes. The SCRs conduct when a

Pin 1 or 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 6.49 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.
