AU3321P1S
1-Line Bi-directional 3.3V ESD Protection Diode
Description
Mechanical Characteristics
The AU3321P1S is a 3.3V bi-directional ESD protection
diode, utilizing leading monolithic silicon technology to
provide fast response time and ultra low ESD clamping
voltage, making this device an ideal solution for protect-
ing voltage sensitive data and power line. The
AU3321P1S complies with the IEC 61000-4-2 (ESD) with
± 30kV air and ±30kV contact discharge. It is assembled
into an ultra-small 1.0x0.6x0.5mm DFN lead-free pack-
age. The small size and high ESD surge protection make
AU3321P1S an ideal choice to protect cell phone, digital
cameras, audio players and many other portable applica-
tions.
