UCLAMP0508T Datasheet, PDF (1/8 Pages) Semtech Corporation – Low Profile μClampTM 8-Line ESD protection

PROTECTION PRODUCTS - MicroClamp^TM
Description
The μClamp^TM series of TVS arrays are designed to pro-
tect sensitive electronics from damage or latch-up due
to ESD. It is designed to replace multilayer varistors
(MLVs) in portable applications such as cell phones, note-
book computers, and other portable electronics. It fea-
tures large cross-sectional area junctions for conducting
high transient currents. TVS diodes offer desirable char-
acteristics for board level protection including fast re-
sponse time, low operating and clamping voltage, and
no device degradation.
The μClamp^TM0508T is in a 8-pin, RoHS/WEEE compli-
ant, SLP1713P8T package. It measures 1.7 x 1.3 mm
with a nominal height of only 0.4mm. The leads are
spaced at a pitch of 0.4mm and are finished with lead-
free NiPdAu. Each device features eight TVS diodes
with an operating voltage of 5 volts and a maximum
loading capacitance of only 10pF.
They may be used to meet the ESD immunity require-
ments 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 notebook computers.
