SLVU2.8-4.TBT

SLVU2.8-4.TBT 2.8V TVS Array For ESD and Latch-Up Protection Description The SLVU2.8-4.TBT is designed to protect low voltage,CMOS semiconductors from transients caused by electrostatic discharge(ESD),cable discharge events(CDE), lightning and other induced voltage surges. Low capacitance compensation diode is integrated into the TVS to lower the typical capacitance to 6pF per line. The complies with the IEC 61000-4-2 SLVU2.8-4 (ESD) standard with ±30kV air and ±30kV contact discharge. The SLVU2.8-4.TBT is assembled into a 8-pin lead-free SO-8 package. The combination of low leakage, signal integrity and flow through design makes the SLVU2.8-4.TBT an ideal application such as 10/100/1000 Ethernet.
