Description
The AR0502S1 is a 2-line ultra-low capacitance TVS diode array, utilizing leading monolithic silicon technology to provide fast response time and low ESD clamping voltage, making this device an ideal solution for protecting voltage sensitive high-speed data lines. The AR0502S1 has a very low capacitance with a typical value at 0.3pF, and complies with the IEC 61000-4-2 (ESD) with ±25kV air and ±20kV contact discharge. It is assembled into a 4- pin SOT-143 lead-free package. The small size, very low capacitance and high ESD surge protection make AR0502S1 an ideal choice to protect cell phone, digital video interfaces, high speed data ports, and many other portable applications.
