TVS device protects the USB 3.0 interface from ESD

Semtech Corp. (Camarillo, CA) announced the RClamp3346P, a high-performance, ultra-low capacitance transient voltage suppression (TVS) device to protect the USB 3.0 interface in computing and mobile devices from electrostatic discharge (ESD) events. The RClamp3346P supplements Semtech’s current USB protection portfolio by providing ultra-low clamping voltage performance and low dynamic resistance in an easy-to-lay-out package. Current USB 3.0 protection schemes usually call for multiple TVS devices, complicating the design and final bill of materials. The RClamp3346P replaces up to 6 discrete and protects the SuperSpeed pairs plus the high-speed signal lines in a slim 2.7mm by 0.8mm package. Other features include:

• The industry’s lowest overall clamping voltage without impacting the signal quality.
• Less than 0.65pF capacitance into the signal path.
• 3.3V working voltage protection
• Protects 6 I/O line in flow-through package
