UCLAMP3311PQ Datasheet, PDF (1/6 Pages) Semtech Corporation – Low Voltage μClamp® for Automotive Applications

PROTECTION PRODUCTS - MicroClamp^®
Description
The µClamp^®3311PQ transient voltage suppressor is
specifically designed to protect sensitive components
which are connected to low-voltage data and transmis-
sion lines from overvoltage caused by ESD (electro-
static discharge), CDE (cable discharge events), and
EFT (electrical fast transients). It is rated to Grade 3
of AEC-Q100 for use in automotive applications.
The µClamp^®3311PQ 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 µClamp3311PQ is in an 2-pin SLP1006P2 pack-
age. 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 flexibil-
ity to protect single lines in applications where arrays
are not practical. They may be used to meet the ESD
immunity requirements of IEC 61000-4-2. The combi-
nation of low voltage, small size and high ESD surge
capability makes them ideal for protection of sensitive
electronics in automotive applications.
