The USB004 is an ultra low capacitance (typically 3pF) steering diode array. This device provides circuit protection for interfaces and wireless bus applications and portable electronics. The USB004 is ideally suited to protect USB data I/O ports against the effects of ESD and EFT. The USB004 meets the requirements of IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT). At higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major concern. The USB004 offers a ultra low capacitance and low leakage current in a SOT-143 package.
