Additional Details

The FSUSB103UMXF113 features an ultra-small package suitable for high-density applications. It typically provides ESD protection exceeding ±15kV contact discharge per IEC 61000-4-2 standard. The device's low capacitance, often in the picofarad range, ensures that USB data signals are not significantly attenuated. The flow-through pinout design minimizes parasitic inductance, which can degrade signal quality. The clamping voltage is carefully controlled to protect downstream USB transceivers. The device is commonly used in USB 2.0 and USB 3.0 applications. This ESD protection device is a critical component in ensuring the reliable operation of USB ports in a wide range of electronic devices.
