Protection device safeguards MIDDI mobile phones

Semtech Corp. has extended its RailClamp protection family with the introduction of its new RClamp 0504P protection device that features low capacitance and high-surge capacity needed for next-generation clamshell and game-capable mobile phones.

The RClamp0504P targets phones that support the mobile display digital interface (MDDI) standard, a high-speed serial interconnection technology that simplifies the design of clamshell phones by reducing the number of wires that run across the handset's hinge to connect the LCD display to the digital baseband controller. The device is also suitable for the keypad of game-playing phones where rapid key pressing creates a need for low-capacitance protection. They may also find homes in USB and Ethernet ports, and other high-speed data lines.

The 5V RClamp0504P can protect four high-speed data lines operating at up to 2GHz without signal degradation, and features a capacitance of less than 3pF. The new device also features a surge capacity that meets all relevant IEC standards for mobile phones. It provides transient protection for high-speed data lines to IEC 61000-4-2 for ESD (15kV air and 8kV contact), IEC 61000-4-4 for EFT and IEC 61000-4-5 for lightning.

Available in a 1.6-by-1.6mm leadless package with a low 0.6-mm profile, this SLP package is more than 50 percent smaller than the next smallest multi-line device. The size advantage is the result of using the company's single-die design. It also features low leakage current and low clamping voltage.

The lead-free RClamp 0504P meets the European Union's Restriction on Hazardous Substances (RoHS) directive to meet worldwide environmental and regulatory requirements.

Available immediately in production quantities, the RClamp0504P is priced at 39 cents each in quantities of 1,000. The ordering code is RClamp0504P.
