The ESD15VD8B is designed for high-speed digital interfaces requiring minimal signal distortion while maintaining strong ESD immunity. With a 15V working voltage, breakdown range of 15.5–18.5V, and ultra-low junction capacitance of approximately 10pF, it effectively clamps transient voltages to around 18.9V at 1A and 22.5V at 3A. Supporting ±30kV IEC ESD, EFT up to 40A, and compact SOD882 footprint, it is ideal for USB ports, HDMI/DVI, Ethernet, SIM interfaces, and portable electronics.
