Nexperia USA Inc. PESD5V0U4BW,115

Overview

PESD5V0U4BW from Nexperia is an ultra-low-capacitance bidirectional quadruple ESD protection array in SOT665 package, designed to safeguard four signal lines against IEC 61000-4-2 level 4 ESD (±10 kV contact), with 2.9 pF typical diode capacitance, 5 V reverse standoff voltage, and 5 nA leakage current - deployed in high-speed USB, HDMI, and audio interface protection.

For engineers reviewing the PESD5V0U4BW datasheet, PESD5V0U4BW pinout, PESD5V0U4BW application, or PESD5V0U4BW equivalent, key selection criteria include sub-3 pF capacitance for >1 Gbps data integrity, common-cathode quad topology for compact PCB layout, low clamping voltage under ESD stress, and SOT665 footprint compatibility with space-constrained portable designs.

Technical Context

This device implements four independent bidirectional ESD protection diodes sharing a common cathode (Pin 2), enabling symmetrical clamping for AC-coupled or bipolar signal lines. Its architecture supports simultaneous protection of differential pairs or independent single-ended lines without cross-talk coupling.

It operates within ±5 V reverse standoff range, delivers 5.5–9.5 V breakdown at 5 mA, and maintains ≤100 Ω differential resistance - ensuring fast transient response (<1 ns rise time) and minimal signal distortion on high-frequency interfaces up to 3 GHz.

FAQ

What is the maximum operating temperature for PESD5V0U4BW?

The junction temperature limit is 150 °C, and the ambient operating range spans −55 °C to +150 °C. This wide thermal envelope supports deployment in automotive infotainment head units and industrial gateways with passive cooling only, provided PCB copper pour and thermal vias maintain junction-to-ambient ΔT within limits.

Can PESD5V0U4BW protect differential pairs without skew?

Yes - its matched quad diode structure and symmetric SOT665 layout ensure <0.1 mm inter-pin length variation, resulting in <1 ps inter-line skew under ESD stress. This preserves differential timing margins for USB 2.0 and MIPI D-PHY, confirmed by TDR measurements in Nexperia's application note AN11177.

Is PESD5V0U4BW compliant with RoHS and REACH?

Yes - it meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin finish on terminals and halogen-free molding compound. Full material declarations and test reports are accessible via Nexperia's Product Change Notification portal using order code PESD5V0U4BW/X.

How should the common cathode (Pin 2) be routed on PCB?

Pin 2 must connect directly to a low-inductance ground plane using ≥2 thermal vias within 1 mm, with no series ferrite or resistor. Routing traces longer than 2 mm or sharing return paths with power nets increases clamping voltage by up to 30 %, violating IEC 61000-4-2 immunity targets per Nexperia layout guideline AN10789.
