Low Capacitance TVS Arrays protect against lightning surges.
Press Release Summary:
Supplied in SOT23-3 and SOIC-8 packaging, respectively, single-channel SPLV2.8 and 4-channel SPLV2.8-4 Series protect sensitive Ethernet PHYs from lightning-induced transients and ESD. Both diode-compensated TVS arrays present loading capacitance of 3.8 pF to minimize signal degradation while providing up to 24 A (tP=8/20 µs) of lightning or surge protection. Additionally, both devices protect up to ±30 kV and have max reverse standoff voltage of 2.8 V with leakage of 1 µA max.
Original Press Release:
Littelfuse Introduces SPLV2.8 and SPLV2.8-4 Series Low Capacitance, TVS Arrays for Lightning Protection
Newest additions to the SPATM portfolio are designed to protect sensitive Ethernet PHYs from lightning-induced transients and ESD
CHICAGO, Illinois, Littelfuse, Inc. (NASDAQ/NGS:LFUS) today announced the introduction of the SPLV2.8 and SPLV2.8-4 Series, which are, respectively, single- and four-channel diode-compensated TVS arrays for ESD and lightning protection.
The SPLV2.8 (SOT23-3) and SPLV2.8-4 (SOIC-8) present a low loading capacitance of 3.8pF to minimize signal degradation while providing up to 24A (tP=8/20µs) of lightning or surge protection. Additionally, both devices exceed the maximum level (±8kV) of the IEC61000-4-2 ESD standard by protecting up to ±30kV (contact discharge).
The SPLV2.8 and SPLV2.8-4 are particularly suitable for primary or secondary protection in 10/100/1000 Ethernet applications where lightning-induced transients are the main threat. Both devices are ideal for helping Ethernet equipment manufacturers comply with regulatory standards such as GR-1089 (North America), ITU K.20/21 (Europe), YD/T (China), etc.
The new SPLV2.8 and SPLV2.8-4 Series are RoHS compliant and comply with the following IEC standards:
Both devices have a maximum reverse standoff voltage of 2.8V with a low leakage of 1µA (MAX). Furthermore, the SPLV2.8 and SPLV2.8-4 Series provide low clamping voltages during surge events, which can be attributed to their extremely low dynamic resistance of only 0.3W
