PESD3V3L1UA-N 产品概述

PESD3V3L1UA-N是伯恩半导体(BORN) 推出的一款单向ESD防护器件,专为低电压电路的静电放电(ESD)及浪涌防护设计,采用SOD-323小型封装,兼具高防护性能与低功耗特性,适用于消费电子、物联网、可穿戴等小型化产品场景。

一、产品核心定位

该器件属于瞬态电压抑制二极管(TVS)类ESD防护元件,针对工作电压≤3V的敏感电路(如MCU、传感器、低功耗模块等),通过快速响应ESD脉冲、钳位过压至安全范围,避免后级元件因静电或浪涌损坏,同时保持低漏电流,不影响电路正常工作。

二、关键电气参数详解

1. 电压与电流特性

  • 反向截止电压(Vrwm):3V:正常工作时,器件反向截止,仅允许极微小漏电流通过,确保电路无额外功耗;适配1.8V、3V等低电压供电的敏感元件(如MCU、传感器)。
  • 击穿电压(Vbr):4V:比Vrwm略高,ESD脉冲触发时快速击穿导通(响应时间<1ns),将脉冲电流泄放至地,避免后级元件过压损坏。
  • 钳位电压(Vc):15V:脉冲峰值时将电压钳位在15V以内,远低于多数半导体元件的损坏阈值(如MCU过压耐受通常≤20V),有效保护敏感电路。
  • 峰值脉冲电流(Ipp):20A@8/20μs:能承受标准8/20μs浪涌波形的20A峰值电流,应对USB插拔、电源波动等日常浪涌场景。
  • 峰值脉冲功率(Ppp):300W:对应20A脉冲的功率容量,多次脉冲冲击后仍保持防护性能稳定。

2. 其他关键参数

  • 反向漏电流(Ir):1μA:低漏电流设计,不影响低功耗电路的待机电流(如物联网传感器休眠模式)。
  • 结电容(Cj):200pF:适配GPIO、UART、I2C等数字接口,不会对信号传输造成明显干扰;高频场景可搭配低电容器件并联使用。

三、防护性能与标准认证

PESD3V3L1UA-N通过多项国际电磁兼容(EMC)标准,防护能力覆盖:

  • IEC 61000-4-2(ESD):满足接触放电±8kV、空气放电±15kV要求,应对人体静电接触的常见场景。
  • IEC 61000-4-4(EFT):抗电快速瞬变脉冲群干扰,适用于工业/消费电子的电源与信号接口。
  • IEC 61000-4-5(浪涌):耐受±2kV(线对地)/±1kV(线对线)浪涌冲击,应对电源波动、雷击感应等事件。

四、封装与适用场景

1. 封装特点

采用SOD-323封装(尺寸约1.6mm×0.8mm×0.6mm),体积小巧,符合小型化产品的PCB布局需求,可直接贴装于接口、电源端等关键位置。

2. 典型应用方向

  • 消费电子:智能手机、平板的USB Type-C接口、音频接口、充电端口防护;
  • 可穿戴设备:智能手表、手环的传感器(心率、加速度)接口、充电触点防护;
  • 物联网模块:低功耗MCU、无线模块(LoRa、NB-IoT)的信号与电源防护;
  • 小型通信设备:路由器、WiFi模块的LAN/WAN接口、电源输入防护。

五、产品优势总结

  1. 防护与功耗平衡:低漏电流(1μA)不影响待机,高脉冲电流(20A)保障防护;
  2. 小型化适配:SOD-323封装节省PCB空间,适合高密度布局;
  3. 标准合规:满足多项IEC EMC标准,可靠性经认证;
  4. 快速响应:击穿电压与工作电压接近,响应时间<1ns,瞬间抑制过压。

该器件为低电压电路提供可靠的ESD与浪涌防护,是消费电子、物联网等领域小型化产品的优选防护元件。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
