Semtech chip protects USB 3.0 connections

Semtech has a three-pin transient voltage suppression (TVS) array device designed for protecting high-speed differential pairs common in interfaces such as USB 3.0, MHL and HDMI 1.4.

3-pin TVS

The RClamp0552T is housed in a 1.0 x 0.6mm package with a nominal height of only 0.4mm.

Its three leads are spaced at a pitch of 0.34mm, and the flow-through design of the package simplifies PCB layout by allowing the traces to run straight through the device.

Specified transient protection for high speed data lines is rated to: IEC 61000-4-2 (ESD) ±17kV (air), ±17kV (contact).

There is a 5V working voltage protection and capacitance is specified at 0.21pF (typ.) and dynamic resistance of 0.90ohms (typ.)
