AU0522S2
2-Line Bi-directional Low Capacitance TVS Diode Array
Mechanical Characteristics
Description
Package: SOT-23
The AU0522S2 is a 2-line bi-directional low capacitance
TVS diode array, utilizing leading monolithic silicon tech-
nology to provide fast response time and low ESD clamp-
ing voltage, making this device an ideal solution for pro-
tecting voltage sensitive high-speed data lines. The
AU0522S2 has a very low capacitance with a typical val-
ue at 3pF, and complies with the IEC 61000-4-2 (ESD)
standard with ±15kV air and ±8kV contact discharge. It is
assembled into a 3-pin SOT-23 lead-free package. The
small size, very low capacitance and high ESD surge pro-
tection make AU0522S2 an ideal choice to protect cell
phone, digital video interfaces, high speed data ports,
and many other portable applications.
