Semtech’s New ?Clamp® 3381P Provides Superior Protection from ESD and Electrical Overstress in Industrial and Consumer Data Interfaces

CAMARILLO, Calif., July 28, 2016 – Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the ?Clamp^® 3381P, a single-line, 3.3V surge rated transient voltage suppression (TVS) device for safeguarding industrial and consumer interfaces against transient voltage threats.

The ?Clamp3381P achieves an unmatched surge/silicon area ratio offering 25A (8×20µs) surge immunity in an ultra-small 1.0 x 0.6 mm package. This surge handling performance is critical for safeguarding industrial data links to reliably transport data in harsh environments, including Internet of Things (IoT) end nodes, LCD televisions and display banners, tablets, surveillance cameras and optical modules.

Built on Semtech’s industry-leading process technology, the ?Clamp3381P outperforms current industry solutions with nearly ideal ESD clamping characteristics. The dynamic resistance of the ?Clamp3381P is only 0.025 Ohms, making the I-V curve characteristics of the device close to that of an ideal diode.

“The leap in performance achieved by the ?Clamp3381P is truly a milestone for Semtech and represents a new platform of protection performance we can bring to the design community,” said Rick Hansen, Product Marketing Director for Semtech’s Protection Products. “The ?Clamp3381P is a breakthrough device that we believe will have wide adoption with our broad customer base.”
