deScRiPtion

The SRV2.8-4 is an ultra low capacitance steering diode/TVS array. This device can be used in applications such as video cards, SMART phones, Gigabit Ethernet and other computer interfaces. Designed for ESD protection, the SRV2.8-4 can clamp the effects of electrical fast transients on the power bus. The SRV2.8-4 combines low capacitance steering diodes for up to four individual data or transmission lines and one TVS diode for power bus protection. This device is available in the space-saving SOT-23-6 package configuration, which minimizes lead inductance to prevent overshoot voltages during high ESD current events. The SRV2.8-4 meets the IEC 61000-4-2, 61000-4-2 and 61000-4-5 requirements.
