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
3.3 volts.
The µClamp
TM
3324P is a solid-state device designed
specifically for transient suppression. It is constructed
using Semtech’s proprietary EPD process technology.
The EPD process provides low standoff voltages with
significant reductions in leakage currents and capaci-
tance over traditional pn junction processes. They offer
desirable characteristics for board level protection
including fast response time, low clamping voltage and
no device degradation.
The µClamp3324P 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 µClamp3324P is in an 8-pin, RoHs compliant,
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 pack-
age makes it ideal for use in portable electronics such
as cell phones, digital still cameras, and notebook
computers.
