Nexperia 2-Element Uni-Directional ESD Protection Diode, 6V Breakdown, 5-Pin WLCSP PESD1USB3SZ

The Nexperia PESD1USB3SZ is a 2-element uni-directional ESD protection diode specially engineered for high-frequency differential interfaces and sensitive electronic circuits. This advanced device is housed in a compact 5-pin WLCSP surface mount package, providing superior ESD protection for USB ports, camera and display interfaces, and MIPI signals commonly found in portable devices. Its minimum breakdown voltage of 6 V ensures reliable suppression of ESD events while maintaining signal integrity.

At the heart of the PESD1USB3SZ are two integrated elements, which work together to deliver strong common-mode suppression (>14 dB) across RF bands from 500 MHz to greater than 8 GHz. This feature is critical for modern GSM, 3G, and LTE applications, where both high protection and clear signal transmission are necessary. The device's wide differential passband (>2 GHz) allows for fast and accurate communications without distortion, supporting LVDS, USB, and other high-speed data protocols.

Designed to withstand harsh environments, the diode is automotive qualified per AEC-Q101, and exceeds IEC 61000-4-2 standards, with ESD ruggedness surpassing 15 kV contact (well above the typical 8 kV test level). With a maximum peak pulse current capability of 8 A, the PESD1USB3SZ is well-suited for applications where robust ESD protection is required.

The thin form factor (maximum package height of 0.5 mm, length 1.22 mm, width 0.82 mm) makes it ideal for compact, densely populated circuit boards, such as those found in smartphones, tablets, wearables, and automotive electronic modules. Its low reverse leakage current (100 nA maximum) also ensures minimal power loss and effective protection without unnecessary drain on system resources.

The PESD1USB3SZ operates reliably in ambient temperatures from -40°C to 85°C, ensuring thermal stability for industrial, laboratory, and automotive environments. The surface-mount WLCSP package enables automated assembly and deployment for high-volume manufacturing.
