4-Line ESD protection
PROTECTION PRODUCTS - EMIClamp®
Features
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.
Transient protection for data lines to
IEC 61000-4-2 (ESD) ±17kV (air), ±12kV (contact)
IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)
Cable Discharge Event (CDE)
Protects four data lines
TVS working voltage: 5V
Series Resistor: 1K Ohm
Capacitance: 15pF (Maximum at VR = 0V)
Low leakage current (<100nA)
Solid-state silicon-avalanche technology
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.
Mechanical Characteristics
SLP2116P8T package
Pb-Free, Halogen Free, RoHS/WEEE Compliant
Nominal Dimensions: 2.1 x 1.6 x 0.4 mm
Lead Finish: NiPdAu
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.

Circuit Board Layout Recommendations for Suppres-
sion of ESD.
15pF
Tab
Good circuit board layout is critical for the suppression
of ESD induced transients. The following guidelines are
recommended:
z
z
z
z
Place the TVS near the input terminals or connec-
tors to restrict transient coupling.
Minimize the path length between the TVS and the
protected line.
Minimize all conductive loops including power and
ground loops.
The ESD transient return path to ground should be
kept as short as possible.
z
z
Never run critical signals near board edges.
Use ground planes whenever possible.
