PROTECTION PRODUCTS - MicroClampTM
Description
The μClampTM series of TVS arrays are designed to pro-
tect sensitive electronics from damage or latch-up due
to ESD. It is designed to replace single line devices such
as multilayer varistors (MLVs) in space constrained ap-
plications such as cell phones, notebook computers, and
other portable electronics. It features large cross-sec-
tional area junctions for conducting high transient cur-
rents. TVS diodes offer desirable characteristics for
board level protection including fast response time, low
operating and clamping voltage, and no device degrada-
tion.
The μClampTM0544P is in a 10-pin, RoHS/WEEE compli-
ant, SLP2510P8 package. It measures 2.5 x 1.0 with
a nominal height of 0.58mm. The leads are spaced at
a pitch of 0.5mm and are finished with lead-free
NiPdAu. They are designed for easy PCB layout by
allowing the traces to run straight through the device.
Each device features four TVS diodes with an operat-
ing voltage of 5 volts and a maximum loading capaci-
tance 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.
