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 multilayer varistors
(MLVs) in portable applications. It features large cross-
sectional area junctions for conducting high transient cur-
rents. It offers superior electrical characteristics such
as lower clamping voltage and no device degradation
when compared to MLVs. They offer desirable charac-
teristics for board level protection including fast response
time, low operating and clamping voltage, and no device
degradation.
The µClampTM1211P is in a 2-pin, RoHS/WEEE
compliant, 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 bidirectional line operating at
±12 volts. It gives the designer the flexibility 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, 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.
