DESCRIPTION
FEATURES
GESD3Z3.3L is a low-capacitance Transient
Voltage Suppressor (TVS) designed to provide
electrostatic discharge (ESD) protection for
high-speed data interfaces. With typical
capacitance of 0.4pF, GESD3Z3.3L is designed to
protect parasitic-sensitive systems against
over-voltage and over-current transient events. It
complies with IEC 61000-4-2 (ESD), Level 4
(±15kV air, ±8kV contact discharge), IEC
61000-4-4 (electrical fast transient - EFT) (40A,
5/50 ns), very fast charged device model (CDM)
ESD and cable discharge event (CDE), etc.
GESD3Z3.3L uses ultra-small SOD-323 package.
Each GESD3Z3.3L device can protect one
high-speed data line. It offers system designers
flexibility to protect single data line where space is
a premium concern. The combined features of low
capacitance, ultra-small size and high ESD
robustness make GESD3Z3.3L ideal for
high-speed data port and high-frequency line (e.g.,
USB 2.0 & antenna line) applications, such as
cellular phones and HD visual devices.
