The UCLAMP0501P.TCT is a single-line, unidirectional ESD protection diode from Semtech that is designed to guard against electro-static discharge occurring from external sources. This device provides bidirectional ESD protection ofport pins, such as USB, RS-232, IEEE1394, Ethernet, and more. The diode features ultra-low capacitance of 0.3pF for signal protection and has an IEC-61000-4-2 ESD Human Body Model rating of 15kV. Additionally, the UCLAMP0501P.TCT is able to withstand up to 5A of continuous current and is rated for peak pulses of 10A.
