1-Line Bi-directional TVS Diode with An Ultra Low Capacitance of 0.3pF typical

PublishTime： 2021-06-06 Article Source：Applied Power

Applied Power's AR0521D3 is a bi-directional TVS diode, 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 AR0521D3 has an ultra-low capacitance with a typical value at 0.3pF and complies with the IEC 61000-4-2 (ESD) with ±25kV air and ±22kV contact discharge. It is assembled into a SOD-323 lead-free package. The small size, ultra-low capacitance, and high ESD surge protection make AR0521D3 an ideal choice to protect cell phones, digital video interfaces, and other high-speed ports.
