Description
The AR0508PBA is an ultra low capacitance TVS array,
utilizing leading monolithic silicon technology to provide
fast response time and low ESD clamping voltage, mak-
ing this device an ideal solution for protecting voltage
sensitive high-speed data lines. The AR0508PBA has an
ultra-low capacitance with a typical value at 0.5pF, and
complies with the IEC 61000-4-2 (ESD) with ±25kV air
and ±20kV contact discharge. It is assembled into a 9-pin
lead-free DFN package. The flow through style package
allows for easy PCB layout and matched trace lengths
necessary to maintain consistent impedance between
high speed differential lines. The small size, ultra-low
capacitance and high ESD surge protection make
AR0508PBA an ideal choice to protect HDMI 1.4, USB
3.0 and other high speed ports.
