Low Voltage TVS
for ESD Protection
Description
Features
Circuit Diagram Package
Revision 02/15/2008
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
3305P 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 μClamp3305P may be used to meet the immunity
requirements of IEC 61000-4-2, level 4 (±15kV air,
±8kV contact discharge). It is packaged in an ultra
small SLP1616P6 package with a low profile of only
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. The small
package makes it ideal for use in portable electronics
such as cell phones, digital still cameras, and notebook
computers.
