Semtech Expands its USB 3.0 Protection Platform with RClamp® 3346P – New 6-line 3.3V SCR TVS Protection Device

RClamp3346P Provides a Single Chip Protection Solution Designed to Meet the Demanding Performance Requirements of USB 3.0

Camarillo, California - January 13, 2015

Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today 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.

Built on Semtech’s highly differentiated SCR process technology, the RClamp3346P achieves the industry’s lowest overall clamping voltage without impacting the signal quality. Designed to meet the high operating data rate of the USB 3.0 interface, this device introduces less than 0.65pF capacitance into the signal path. 

“A major trend with the newest generation of controllers is the increased ESD sensitivity due to shrinking process geometry.” said Rick Hansen, Product Marketing Director for Semtech’s Protection Products.  “We believe the RClamp3346P is the perfect solution, giving designers peace of mind knowing the system is well protected from ESD transients.”

The RClamp3346P is also qualified to grade 1 of the AEC-Q100 automotive reliability standard in order to provide the highest level of component reliability. 

Key Features of the RClamp3346P

  • Transient protection for high-speed data lines to: IEC 61000-4-2 (ESD) ±20kV (air), ±12kV (contact); IEC 61000-4-4 (EFT) 40A (5/50ns); IEC 61000-4-5 (lightning) 5A (8/20μs)
  • 3.3V working voltage protection
  • Protects 6 I/O line in flow-through package
  • Low capacitance (<0.65pF line-to-ground)
  • Low dynamic resistance (0.15Ohm typical)
  • Pb Free and RoHS/WEEE compliant

Pricing and Availability 

The RClamp3346P (order code: RClamp3346P.TNT) is available immediately in production quantities and is priced at $0.37 each in 3,000-piece reels. Semtech offers comprehensive design assistance, including field- and factory-based support. Datasheets, volume pricing and delivery quotes, as well as evaluation kits and samples, are available by contacting info@semtech.com.
