PROTECTION PRODUCTS - MicroClampTM
Description
The μClampTM 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 μClampTM3301P 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 μClampTM3301P 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.
