PROTECTION PRODUCTS - µClamp®
Description
µClamp® TVS diodes are designed to protect sensitive
electronics from damage or latch-up due to EOS, light-
ning, CDE, and ESD. They feature large cross-sectional
area junctions for conducting high transient currents.
These devices offer desirable characteristics for board
level protection including fast response time, low operat-
ing and clamping voltage, and no device degradation.
µClamp®3381P features extremely good protection char-
acteristics highlighted by high surge current capability
(25A, tp=8/20us), low peak ESD clamping voltage, and
high ESD withstand voltage (+/-30kV contact per IEC
61000-4-2). Typical dynamic resistance is among the
industry’s best at 0.025 Ohms. Each device will protect
one data or power line operating at 3.3 Volts.
µClamp3381P is in a 2-pin SGP1006N2 package mea-
suring 1.0 x 0.6 x 0.5mm. Leads are spaced at a pitch
of 0.65mm and feature a lead-free finish. The combina-
tion of small size, low operating voltage, and high ESD
surge capability makes them ideal for protection of volt-
age bus lines in optical modules, LCD televisions, and
tablet computers.
