Package: SOD-323
The AR2421D3 is an bi-directional TVS diode, utilizing
leading monolithic silicon technology to provide fast re-
sponse time and low ESD clamping voltage, making this
device an ideal solution for protecting voltage sensitive
high-speed data lines. The AR2421D3 has an ultra-low
capacitance with a typical value at 0.3pF, and complies
with the IEC 61000-4-2 (ESD) with ±15kV air and ±8kV
contact discharge. The small size, ultra-low capacitance
and high ESD surge protection make AR2421D3 an ideal
choice to protect cell phone, digital visual interfaces,
HDMI, DVI, USB2.0, USB3.0, and other high speed ports.
