Package: SOT-523
The AU0521S5 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
AU0521S5 has a low capacitance with a typical value at
16pF, and complies with the IEC 61000-4-2 (ESD) with
±30kV air and ±30kV contact discharge. It is assembled
into a 3-pin SOT-523 lead-free package. The small size,
very low capacitance and high ESD surge protection
make AU0521S5 an ideal choice to protect cell phone,
digital video interfaces, high speed data ports, and many
other portable applications.
