ECLAMP0504T Datasheet, PDF (1/7 Pages) Semtech Corporation – Low Profile EClamp® 4-Line ESD protection

PROTECTION PRODUCTS _{- EMIClamp}^®
Description
The EClamp^®0504T is designed to protect sensitive elec-
tronics from damage or latch-up due to ESD. This state-
of-the-art device utilizes solid-state silicon-avalanche
technology for superior clamping performance and DC
electrical characteristics. It has been optimized for pro-
tection of digital lines in cellular phones and other
portable electronics.
The device replaces up to eight discrete components in
a small footprint. It consists of a TVS diode and a
series 1K Ohm resistor on each line. The TVS diode
presents a maximum loading capacitance of 15pF for
maximum signal integrity. The TVS diodes provide
effective suppression of ESD voltages in excess of
±15kV (air discharge) and ±8kV (contact discharge) per
IEC 61000-4-2, level 4.
The EClamp0504T is in an 8-pin SLP2116P8T package.
It measures 2.1 x 1.6 x 0.40mm. The leads are
spaced at a pitch of 0.5mm and are finished with lead-
free NiPdAu. Each device will protect four lines operat-
ing at 5 volts. It gives the designer the flexibility to
protect single lines in applications where arrays are not
practical. The small package makes it ideal for use in
portable electronics such as cell phones, digital still
cameras, and PDAs.
