Low Voltage μClampTM  
for ESD and CDE Protection  
PROTECTION PRODUCTS - MicroClampTM  
Features  
Description  
The μClampTM series of Transient Voltage Suppressors  
(TVS) are designed to replace multilayer varistors  
(MLVs) in portable applications where low operating  
voltage is vital. They offer superior electrical characteris-  
tics such as lower clamping voltage and no device  
degradation when compared to MLVs. They are de-  
signed to protect sensitive semiconductor components  
from damage or upset due to electrostatic discharge  
(ESD), lightning, electrical fast transients (EFT), and  
cable discharge events (CDE).  
‹ Transient protection for data lines to  
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)  
IEC 61000-4-4 (EFT) 40A (tp = 5/50ns)  
Cable Discharge Event (CDE)  
‹ Ultra-small package (1.0 x 0.6 x 0.5mm)  
‹ Protects one data line  
‹ Low clamping voltage  
‹ Working voltage: 3.3V  
‹ Low leakage current  
‹ Solid-state silicon-avalanche technology  
The μClampTM3311P is constructed using Semtech’s  
proprietary EPD process technology. The EPD process  
provides low standoff voltages with significant reduc-  
tions in leakage currents and capacitance over silicon-  
avalanche diode processes. They feature a true  
operating voltage of 3.3 volts for superior protection  
when compared to traditional pn junction devices.  
Mechanical Characteristics  
‹ SLP1006P2 package  
‹ RoHS/WEEE Compliant  
‹ Nominal Dimensions: 1.0 x 0.6 x 0.5 mm  
‹ Lead Finish: NiPdAu  
‹ Molding compound flammability rating: UL 94V-0  
‹ Marking : Marking code, cathode band  
‹ Packaging : Tape and Reel  
The μClampTM3311P is in an 2-pin, RoHS/WEEE compli-  
ant, SLP1006P2 package. It measures 1.0 x 0.6 x  
0.5mm. 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 3.3 volts. It gives the  
designer the flexibility to protect single lines in applica-  
tions where arrays are not practical. They may be used  
to meet the ESD immunity requirements of IEC 61000-  
4-2, Level 4 (±15kV air, ±8kV contact discharge). The  
combination of small size and high ESD surge capability  
makes them ideal for use in portable applications such  
as cellular phones, digital cameras, and MP3 players.  
Applications  
‹ Cellular Handsets & Accessories  
‹ Notebooks & Handhelds  
‹ Portable Instrumentation  
‹ Digital Cameras  
‹ Peripherals  
‹ MP3 Players
