Littelfuse Announces Significant Enhancement to SPLV2.8 and SPLV2.8-4 Series TVS Diode Arrays (SPATM Family) for ESD and Lightning-Induced Transient Protection
Littelfuse, Inc. today announced the enhanced versions of the SPLV2.8 and SPLV2.8-4 Series which are, respectively, single- and four-channel TVS Diode Arrays (SPATM Family) for ESD (electrostatic discharge) and lightning-induced transient protection.
The improvements of the SPLV2.8 (SOT23-3) and SPLV2.8-4 (SOIC-8) Series include a reduced loading capacitance of 2pF to minimize signal degradation for 1GbE interfaces while providing a much higher level of lightning immunity of 40A (tP=8/20µs). 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:
● ESD, IEC61000-4-2, ±30kV (contact), ±30kV (air)
● EFT, IEC61000-4-4, 40A (5/50ns)
● Lightning, IEC61000-4-5, 40A (8/20µs)

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 0.4Ω .
