    Littelfuse new product SP3384NUTG

    The new SP3384NUTG series for 10GbE



    Littelfuse has announced its SP3384NUTG series of low capacitance TVS diode arrays for protection of 10 Gigabit Ethernet (GbE) lines. These new devices are meant to guard sensitive high-speed network communications lines from up to to 15 amps and from a maximum of ±30kV of electrostatic discharge (ESD), as defined by IEC 61000-4-5 2nd edition and IEC 61000-4-2, respectively.


      SP3384NUTG series of low capacitance TVS diode 

    Left unprotected, network communications are vulnerable to hazards not limited to lightning-induced surges, ESD, electrical fast transients (EFT) and cable discharge events.
    Through a combination of low clamping voltage and low capacitance,
    the new device is designed to protect 2.5, 5, and even 10 GbE differential data lines while suffering no signal degradation.

    * Key Features Capacitance for each 1/0 line is only 0.5 pF Typical Clamping voltage (tp=8/20μs) is 4 volts @Ipp = 1 amp 12 volts @Ipp = 15 amp Protection is provided for four channels, or two differential data pairs The units actually exceed IEC (International Electrotechnical Commission) ESD protection standards Leaking current at 3.3 volts is 3 nA typical and 40 nA maximum.
