Nexperia USA Inc. PESD5V0S4UF,115

Overview

PESD5V0S4UF,115 from Nexperia is a unidirectional quadruple ESD protection diode array in SOT886 package, designed to protect four signal lines with 5.0 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact ESD rating, 110 W peak pulse power (8/20 µs), and 85–220 pF capacitance - deployed in USB 2.0 data lines of portable electronics.

For engineers reviewing the PESD5V0S4UF,115 datasheet, PESD5V0S4UF,115 pinout, PESD5V0S4UF,115 application, or PESD5V0S4UF,115 equivalent, key selection criteria include clamping voltage under 12 V at 10 A surge, ultra-low 4 nA leakage at 4.3 V, AEC-Q101 qualification, and compact 1.0 × 1.45 × 0.5 mm footprint for high-density PCB layouts.

Technical Context

This device implements four independent unidirectional silicon avalanche diodes sharing two common anode terminals (pins 2 and 5), enabling low-impedance transient shunting from any protected line (pins 1, 3, 4, 6) to either anode rail. Its architecture supports bidirectional signal paths when paired anodes are tied to separate supply domains.

Clamping behavior is defined by a 6.8 V typical breakdown voltage (1 mA), differential resistance ≤200 Ω, and 11 V max clamping at 10 A IPP - meeting IEC 61000-4-5 surge and level-4 ESD requirements. Capacitance remains stable below 220 pF across 0–5 V reverse bias, critical for high-speed interfaces.

FAQ

What is the maximum operating temperature for PESD5V0S4UF,115?

The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C. Its thermal performance is validated per IEC 61000-4-2 and AEC-Q101 test conditions, ensuring stable clamping behavior across automotive under-hood and industrial control environments.

Can PESD5V0S4UF,115 protect bidirectional signals like I²C?

No - it is a unidirectional array. For bidirectional buses such as I²C, two devices must be used back-to-back or a dedicated bidirectional ESD array (e.g., PESD5V0X1BL) is required. Its pin 2 and pin 5 anodes are not internally connected, so external wiring determines polarity.

How does the dual-common-anode structure improve PCB layout?

The separate anodes (pins 2 and 5) allow grouping of protected lines into two independent clamping domains - reducing ground bounce in mixed-signal systems and enabling localized return paths for sensitive analog or RF traces without shared impedance.

Is the 30 kV ESD rating applicable to all four channels simultaneously?

Yes - the 30 kV rating per IEC 61000-4-2 contact discharge applies individually to each cathode terminal (pins 1, 3, 4, 6) when tested against its respective common anode (pins 2 or 5). The device maintains full rating across all channels under sequential or simultaneous stress per Nexperia's qualification report.
