Semtech Extends MicroClamp® Platform with Industry
Company Grows Its Sub 5V Market Leadership with Single-Line uClamp2501T and uClamp2511T
Camarillo, California - October 22, 2009Semtech Corp. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the uClamp2501T and uClamp2511T, 2.5V single-line MicroClamp® transient voltage suppression (TVS) devices. These TVS devices are targeted at the one of the fastest growing mobile phone markets - multimedia smart phones with touchscreens, docking ports, memory slots and other interfaces that open the possibility of potential damage from ElectroStatic Discharge (ESD).
For performance, these phones rely on the latest generation of chipsets that operate on a working voltage of 2.5V or lower. Manufactured on sub 65nm technology, these chipsets are much more susceptible to ESD damage. The uClamp25x1T parts are ideal for these systems because they feature less than half of the turn-on voltage of a 5V part. This allows the ESD protection device to react much faster to transient events, thus reducing current flowing into the protected IC. Clamping voltage, a critical element in protecting sensitive ICs, is also minimized.
These parts bring to the MicroClamp platform Semtech's proprietary EPD process technology, an improvement over silicon avalanche diode processes that delivers low standoff voltages to reduce leakage current and capacitance. Semtech became the first company to debut a true 2.5V TVS when it launched the four-line, ultra-low capacitance RClamp2504N and RClamp2504P in May 2009.
The use of low voltage chipsets also helps these smartphones to have a longer battery life. With standard features including cameras, Internet browsing, email and texting in addition to voice communications, smartphone designers need to take advantage of every opportunity to extend the battery life, such as choosing parts with low leakage current like the uClamp25x1T devices, which feature a 10nA leakage current. Both TVS devices come in ultra small 1.0 x 0.6 x 0.4mm package to provide flexible protection anywhere it's needed.
The uClamp25x1T devices provide industry-standard protection from electrostatic discharge (ESD), lightning, electrical fast transients (EFT), and cable discharge events (CDE). The uClamp2501T is unidirectional and the uClamp2511T is bidirectional. The uClamp2511T offers a low capacitance of 10pF maximum, while the uClamp2501T is rated at 30pF.
"Portable-system designers that need to balance the increased battery life made possible by low voltage chipsets with the reliability that comes with high-quality protection now have a great option," said Rick Hansen, Semtech Marketing Director for Protection Products. "Providing the high-quality protection of the MicroClamp platform with both low-voltage and low leakage is a significant breakthrough."
While these products offer designers the benefit of significant board space savings, their small size and RoHS & WEEE compliance also contributes to energy conservation and hazardous waste reduction.
