1-Line Bi-directional TVS Diode with Has A Low Capacitance with A Typical Value at 1pF

PublishTime： 2021-06-09 Article Source：Applied Power

The AR0511D3 is a 5V 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 AR0511D3 has a low capacitance with a typical value at 1pF and complies with the IEC 61000-4-2 (ESD) with ±30kV air and ±30kV contact discharge. It is assembled into a lead-free SOD-323 package. The small size, low capacitance, and high ESD surge protection make AR0511D3 an ideal choice to protect cell phones, wireless systems, and communication equipment.
