Bi-directional TVS Diode Assembled into A SOD-523 Lead-free Package

PublishTime： 2021-06-17 Article Source：Applied Power

The AR0521D5 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 AR0521D5 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-523 lead-free package. The small size, ultra-low capacitance, and high ESD surge protection make AR0521D5 an ideal choice to protect cell phones, digital visual interfaces, and other high-speed ports.
