AU0542S2L
2-Line Bi-directional TVS Diode Array
Mechanical Characteristics
Description
Package: SOT-23
The AU0542S2L is a 2-line bi-directional TVS diode ar-
ray, utilizing leading monolithic silicon technology to pro-
vide fast response time and low ESD clamping voltage,
making this device an ideal solution for protecting voltage
sensitive high-speed data lines. The AU0542S2L com-
plies with the IEC 61000-4-2 (ESD) standard with ±30kV
air and ±30kV contact discharge. It is assembled into a 3-
pin SOT-23 lead-free package. The small size and high
ESD surge protection make AU0542S2L an ideal choice
to protect cell phone, digital video interfaces, high speed
data ports, and many other portable applications.
