ESD56151W04-2/TR 产品概述

一、产品简介

ESD56151W04-2/TR 是东沃(DOWO)推出的一款单通道双向瞬态抑制二极管(TVS),采用 SOD-323 小封装,专为电子设备的静电放电(ESD)和浪涌保护而设计。该器件在保证低漏电的同时,提供高能量吸收能力和快速响应特性,适用于需要体积小、安装便捷的表面贴装电路保护场合。

主要参数概览:

  • 极性:双向
  • 工作反向截止电压 Vrwm:4.5 V
  • 击穿电压(典型):4.8 V
  • 钳位电压 Vc:14.5 V
  • 峰值脉冲电流 Ipp:160 A
  • 峰值脉冲功率 Ppp:2.5 kW
  • 反向泄漏电流 Ir:1 µA
  • 结电容 Cj:330 pF
  • 通道数:单路
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 防护等级:符合 IEC 61000-4-5(浪涌)和 IEC 61000-4-2(静电放电)标准
  • 封装:SOD-323(表面贴装)
  • 类型:ESD 保护器件
  • 品牌:DOWO(东沃)

二、关键特性与优势

  • 双向保护:适用于可承受正、负极性瞬态事件的信号线,安装时无需区分极性,简化系统设计。
  • 低漏电:典型反向漏电仅 1 µA,可最大限度减少待机功耗,适合电池供电或低功耗系统。
  • 高吸收能量:峰值脉冲电流 160 A 与峰值脉冲功率 2.5 kW,为常见的 ESD 和浪涌事件提供有效钳位与能量散耗能力。
  • 快速响应:作为 TVS 器件,能在纳秒级响应突发的静电或浪涌脉冲,保护下游敏感器件免受损坏。
  • 紧凑封装:SOD-323 小体积、便于自动贴片,适合空间受限的便携设备与消费类电子产品。
  • 工业级温度范围:-55 ℃ 至 +125 ℃,适合多种环境条件下工作。

三、典型应用场景

  • 手机、平板与便携设备的外部接口保护(如耳机口、充电/数据端口)
  • USB、串口、CAN、I2C 等低压信号线的过压与 ESD 防护(注意结电容对高速信号的影响)
  • 工业控制、测量仪表和物联网终端的接口保护,满足 IEC 静电与浪涌等级要求
  • 任何需要体积小、可靠的单通道瞬态抑制解决方案的应用场合

四、使用与布局建议

  • 尽量将器件放置于受保护端口或连接器附近,靠近入线点以减少走线感抗与环路面积。
  • 使用短、宽的走线将 TVS 的接地脚直接回到器件主地(或接地层),以优化浪涌回流路径并降低钳位电压。
  • 由于结电容为 330 pF,若用于高速差分信号(例如高速 USB、HDMI)可能影响信号完整性,应在选型时评估对波形的影响;对较低速或容差较高的接口非常合适。
  • SOD-323 为表贴封装,建议采用推荐焊盘和回流工艺,避免过热或不良焊点导致可靠性问题。
  • 在高可靠性应用中,配合器件的工作温度范围进行环境验证与老化测试。

五、封装与订购信息

  • 型号示例:ESD56151W04-2/TR(/TR 表示卷带盘装,适合自动贴片生产线)
  • 封装:SOD-323(小体积、适合自动化装配)
    在订购时,请确认包装方式(散装或卷带)、接受的最低订购量以及是否需要器件认证或额外测试报告。

六、注意事项

  • 在选型前,请核对目标系统的最大工作电压,ESD56151W04-2/TR 的 Vrwm 为 4.5 V,适合保护工作电压不高于此值或在此范围内的信号。
  • 结电容较高时对高频信号可能造成负面影响,必要时在系统层面评估信号完整性或考虑低电容的替代型号。
  • 器件虽符合 IEC 61000-4-2/4-5 标准,但具体防护等级取决于系统整体设计(接地、布局、配合器件等),建议在整机层面进行实测验证。

如需该型号的数据手册、封装尺寸图或在特定应用中的参考设计(例如与电感、电容并联的滤波/保护组合),我可以进一步提供详细资料与建议。

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
