uClamp3311T
Low Profile µClamp
1-Line ESD protection
Revision 4/28/2015
SLP1006P2T (Bottom View)
Nominal Dimensions (mm)
The µClamp
series of Transient Voltage Suppressors
(TVS) are designed to replace multilayer varistors
(MLVs) in portable applications such as cell phones,
notebook computers, and PDAs. They offer superior
electrical characteristics such as lower clamping
voltage and no device degradation when compared to
MLVs. They are designed to protect sensitive semicon-
ductor components from damage or upset due to
electrostatic discharge (ESD), lightning, electrical fast
transients (EFT), and cable discharge events (CDE).
The µClamp
3311T 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.
The µClamp3311T is in a 2-pin SLP1006P2T package.
It measures 1.0 x 0.6 x 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
3.3 volts. It gives the designer the flexibility to protect
single lines in applications where arrays are not practi-
cal. They may be used to meet the ESD immunity
requirements of IEC 61000-4-2. 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.
