ECLAMP0501T Datasheet, PDF (1/7 Pages) Semtech Corporation – Low Profile EClamp®1-Line ESD protection

PROTECTION PRODUCTS - EMIClamp^®
Description
The EClamp^® 0501T TVS diode is designed to protect sen-
sitive electronics from damage or latch-up due to ESD.
This state-of-the-art device utilizes solid-state silicon-ava-
lanche technology for superior clamping performance and
DC electrical characteristics. It has been optimized for
protection of digital lines in cellular phones and other
portable electronics.
The device replaces two discrete components in a
small footprint. It consists of a TVS diode and a series
1K Ohm resistor. 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 EClamp0501T is in a 3-pin, SLP1006P3T package.
It measures 1.0 x 0.6 mm with a nominal height of only
0.4mm. The leads are spaced at a pitch of 0.65mm
and are finished with lead-free NiPdAu. Each device
will protect one line operating at 5 volts. It gives the
designer the flexibility to protect single lines in applica-
tions where arrays are not practical. The small pack-
age makes it ideal for use in portable electronics such
as cell phones, digital still cameras, and PDAs.
