Features
The EClamp 0501T TVS diode is designed to protect sensitive electronics 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
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 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.

Circuit Diagram
This device is designed to protect one data line. The
device is unidirectional and may be used on lines
where the signal polarity is above ground. The cathode
band should be placed towards the line that is to be
protected.

Circuit Board Layout Recommendations for Suppression of ESD.
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
z Place the TVS near the input terminals or connectors to restrict transient coupling.
z Minimize the path length between the TVS and the
protected line.
z Minimize all conductive loops including power and
ground loops.
z The ESD transient return path to ground should be
kept as short as possible.
z Never run critical signals near board edges.
z Use ground planes whenever possible.
