Overview
The PESD3V3X1BL,315 from Nexperia is an ultra-low capacitance, bidirectional ESD protection diode designed for high-speed signal integrity and robust transient suppression. Built in an extremely compact DFN1006-2 (SOD882) package, it protects a single data line from ESD strikes up to ±9 kV (IEC 61000-4-2 contact discharge) and ±10 kV (HBM). With a typical diode capacitance of only 1.3 pF and leakage current as low as 1 nA, the device is optimized for ultra-sensitive RF, audio, video, and high-speed data interfaces.
