The ESD5V0D9 is optimized for protecting voltage-sensitive components in compact portable electronics. With a 5V reverse standoff voltage, fast transient response, and clamping performance around 9.8V at low surge currents, it minimizes overstress on delicate IC structures during electrostatic discharge events. Featuring low junction capacitance of approximately 25pF and reliable thermal behavior, it is ideally suited for smartphones, digital cameras, portable power rails, and high-density consumer electronics requiring efficient transient protection in minimal space.
