PROTECTION PRODUCTS - MicroClampTM
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).
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.
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.
