UCLAMP0524P Datasheet, PDF (1/8 Pages) Semtech Corporation – Low Voltage TVS for ESD Protection

PROTECTION PRODUCTS - MicroClamp^TM
Description
The µClamp^TM series of TVS arrays are designed to
protect sensitive electronics from damage or latch-up
due to ESD, lightning, and other voltage-induced
transient events. Each device will protect up to four
lines operating at 5 volts.
The µClamp^TM0524P is a solid-state device designed
specifically for transient suppression. It is designed to
replace multilayer varistors (MLVs) in portable applica-
tions such as cell phones, notebook computers, and
PDAs. It features large cross-sectional area junctions for
conducting high transient currents. It offers superior
electrical characteristics such as lower clamping voltage
and no device degradation when compared to MLVs.
The µClamp^TM0524P may be used to meet the immunity
requirements of IEC 61000-4-2, level 4 (±15kV air, ±8kV
contact discharge). The “flow-thru” design of the device
results in enhanced ESD performance due to reduced
board trace inductance. The result is lower clamping
voltage and a higher level of protection when compared
to conventional TVS devices.
The µClamp0524P is in an 8-pin, RoHS/WEEE compli-
ant, SLP2116P8 package. It measures 2.1 x 1.6 x
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPd. The small package
makes it ideal for use in portable electronics such as cell
phones, digital still cameras, and notebook computers.
