PROTECTION PRODUCTS - µClamp^®
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,
notebook computers, and other portable electronics.
They feature large cross-sectional area junctions for con-
ducting high transient currents. This device offers desir-
able characteristics for board level protection including
fast response time, low operating and clamping voltage,
and no device degradation.
µClamp^®3321ZA features extremely good ESD protec-
tion characteristics highlighted by low typical dynamic
resistance of 0.33 Ohms, low peak ESD clamping volt-
age, and high ESD withstand voltage (+/-15kV contact
per IEC 61000-4-2). Low maximum capacitance (5pF at
VR=0V) minimizes loading on sensitive cirucuits. Each
device will protect one data line operating at 3.3 Volts.
µClamp3321ZA is in a 2-pin SLP0603P2X3F package.
It measures 0.6 x 0.3 mm with a nominal height of only
0.25mm. Leads are finished with NiAu. The small pack-
age 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 tablet PC’s.
