Semtech Expands Mobile Protection Platform with the RClamp® 0552T – A 5V TVS Array for Safeguarding High Speed Differential Lines

Semtech’s RClamp0552T Provides ESD Protection for Dual High Speed Data Lines in Space Constrained Applications

Camarillo, California - April 21, 2015

Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the RClamp® 0552T, a high performance, low capacitance transient voltage suppression (TVS) array device. The RClamp0552T is offered as a three-pin device and protects high speed differential pairs common in interfaces such as USB 3.0, MHL and HDMI 1.4.

Built on Semtech’s highly differentiated process technology that achieves the industry’s lowest clamping voltages, the RClamp0552T delivers optimal transient protection and is housed in a small 1.0 x 0.6mm package with a nominal height of only 0.4mm. In addition, the 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. The combination of small size, low capacitance and high level ESD protection makes the RClamp0552T an ideal solution for protecting high speed differential lines in portable applications such as mobile phones, fitness bands and wearable devices.

The RClamp0552T delivers high performance with a small footprint. With increasing complexity of smartphones, PCB space and device thickness are key considerations when selecting components. Engineers value the small form factor of the RClamp0552T when protecting sensitive components in their designs.

“Robust ESD protection in a small package is more important to portable electronics manufacturers than ever before.” said Rick Hansen, Product Marketing Director for Semtech’s Protection Products. “The RClamp0552T expands Semtech’s growing portable product family and offers ESD protection for high speed differential lines in a small and easy to use package.”
