Description

The UDS08A03L04 component is designed to protect low voltage state-of-the-art CMOS semiconductors from transients caused by electrostatic discharge (ESD), cable discharge events (CDE), lightning and other induced voltage surges. The device provides low stand -off voltages with significant reductions in leakage currents and capacitance over silicon avalanche diode processes. The UDS08A03L04 features integrated low capacitance compensation diodes that reduce the typical capacitance 3pF per line. This combined with low leakage current, means signal integrity preserved in high-speed applications such as 10/100/1000 Ethernet.
