Nexperia USA Inc. PESD5V0L1UA,115

Overview

PESD5V0L1UA from Nexperia is a low-capacitance unidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect single high-speed signal lines against IEC 61000-4-2 level 4 ESD events up to ±26 kV contact discharge, with 25 pF typical capacitance, 12 V clamping voltage at 3.5 A, and 10 nA reverse leakage at 5 V.

For engineers reviewing the PESD5V0L1UA datasheet, PESD5V0L1UA pinout, PESD5V0L1UA application, or PESD5V0L1UA equivalent, key selection criteria include reverse standoff voltage (5 V), clamping performance under 8/20 µs transients, ultra-low capacitance for USB/FireWire signal integrity, and unidirectional polarity alignment with ground-referenced data lines.

Technical Context

This device implements a silicon avalanche diode structure optimized for fast response (<1 ns rise time per IEC 61000-4-2) and low dynamic impedance (30 Ω differential resistance), enabling effective clamping of sub-100 ns ESD pulses before system ICs are stressed. Its unidirectional configuration supports protection of positive-polarity signal lines referenced to ground.

It operates within a −55 °C to +150 °C ambient range and sustains 42 W peak pulse power (8/20 µs) without degradation. The 5 V reverse standoff voltage ensures compatibility with 3.3 V and 5 V logic interfaces while maintaining margin against normal operating voltage excursions.

FAQ

What is the maximum continuous reverse voltage the PESD5V0L1UA can block?

The PESD5V0L1UA has a reverse standoff voltage (VRWM) of 5 V, meaning it reliably blocks up to 5 V DC or peak AC voltage in normal operation without entering breakdown. This rating is tested at 25 °C ambient and ensures no significant leakage current flows below this threshold, preserving signal integrity on 3.3 V and 5 V logic lines.

How does the 25 pF capacitance affect high-speed signal performance?

A 25 pF typical capacitance introduces minimal loading on high-speed lines: for USB 2.0 (480 Mbps), it causes <0.5 dB attenuation at 240 MHz and preserves eye opening. Measured at 1 MHz and 0 V bias, this value remains stable across 0–5 V reverse bias, ensuring consistent signal integrity during both static and transient conditions.

Can PESD5V0L1UA protect bidirectional signal lines like RS-485 or CAN?

No-PESD5V0L1UA is unidirectional and only protects signals referenced to ground with defined polarity (e.g., USB D+, SIM I/O). For true bidirectional lines such as RS-485 or CAN, a symmetric dual-diode array (e.g., PESD5V0S1BA) is required to clamp both positive and negative transients relative to common-mode voltage.

Is thermal derating required for repeated ESD events?

No derating is specified for repetitive ESD events because the device is qualified for ten non-repetitive 26 kV contact discharges per IEC 61000-4-2. Its 150 °C max junction temperature and low thermal mass allow full-rated clamping performance without cumulative heating under standard test conditions.
