uClamp3311Z
Ultra Small μClamp®
1-Line, 3.3V ESD Protection
PROTECTION PRODUCTS - Z-PakTM
Features
Description
μClamp® TVS diodes are designed to protect sensitive
electronics from damage or latch-up due to ESD. They
are designed to replace 0201 size multilayer varistors
(MLVs) in portable applications such as cell phones, note-
book computers, and other portable electronics. They
features large cross-sectional area junctions for conduct-
ing high transient currents. These devices offer desir-
able characteristics for board level protection including
fast response time, low operating and clamping voltage,
and no device degradation.
High ESD withstand Voltage: +/-14kV (Contact) and
+/- 16kV (Air) per IEC 61000-4-2
Able to withstand over 1000 ESD strikes per IEC
61000-4-2 Level 4
Ultra-small 0201 package
Protects one data line
Low reverse current: <10nA typical (VR=5V)
Working voltage: +/- 3.3V
Low capacitance: 6pF typical
Extremely low dynamic resistance: 0.21 Ohms (Typ)
Solid-state silicon-avalanche technology
μClamp®3311Z is constructed using Semtech’s propri-
etary EPD process technology. The EPD process provides
low standoff voltages with significant reductions in leak-
age currents and capacitance over silicon-avalanche di-
ode processes. They feature a true operating voltage of
3.3 volts for superior protection when compared to tra-
ditional pn junction devices.
Mechanical Characteristics
SLP0603P2X3A package
Pb-Free, Halogen Free, RoHS/WEEE Compliant
Nominal Dimensions: 0.6 x 0.3 x 0.25 mm
Lead Finish: NiAu
μClamp3311Z is in a 2-pin SLP0603P2X3A package.
It measures 0.6 x 0.3 mm with a nominal height of only
0.25mm. Leads are finished with lead-free NiAu. Each
device will protect one line operating at 3.3 volts. It
gives the designer the flexibility to protect single lines in
applications where arrays are not practical. 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.
