ESD56031N-2/TR 产品概述

一、产品简介

ESD56031N-2/TR 是 WILLSEMI(韦尔)推出的一款双向瞬态电压抑制器(TVS),用于对静电放电(ESD)和浪涌(Surge)事件进行快速钳位保护。器件采用小型 DFN1006-2L 封装,适合空间受限的消费电子与工业接口保护场景。器件以低反向漏电、较高峰值吸收能力以及对常见抗扰标准的兼容性为设计目标,适用于 5V 及类似电压等级的信号线保护。

二、主要参数

  • 极性:双向(bidirectional)
  • 反向截止电压 Vrwm:4.6 V
  • 击穿电压:4.7 V
  • 钳位电压(典型):10 V
  • 峰值脉冲电流 Ipp:45 A @ 8/20 µs
  • 峰值脉冲功率 Ppp:540 W @ 8/20 µs
  • 反向电流 Ir:1 µA(常温)
  • 结电容 Cj:100 pF
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 防护等级/兼容标准:IEC 61000-4-2、IEC 61000-4-4、IEC 61000-4-5
  • 封装:DFN1006-2L
  • 型号:ESD56031N-2/TR

三、关键特性与优点

  • 双向结构支持对称正负极性瞬态抑制,适合双向数据线或无固定直流偏置的接口。
  • 4.6 V 的 Vrwm 与 4.7 V 的击穿电压,使其适用于 5 V 等电压等级的保护场景。
  • 在 8/20 µs 波形下可承受 45 A 电流峰值与 540 W 脉冲功率,能有效吸收较强的浪涌脉冲。
  • 低漏电(1 µA)有利于对低功耗系统影响最小化。
  • 小型 DFN 包装便于表面贴装,适合高密度 PCB 布局。

四、典型应用

  • USB 接口、GPIO、UART、I2C 等 5V/双向数据线的静电与浪涌保护(需评估结电容对高速信号的影响)。
  • 工业控制接口、通信端口、继电器驱动线等需抗干扰保护的场合。
  • 消费类与便携设备的外部连接口保护。

五、设计与使用建议

  • 尽量将 TVS 靠近受保护的连接器或接口放置,走线短且宽,降低感抗与寄生电感,提升吸收效率。
  • 对高速信号(例如 USB2.0 高速)应注意结电容 100 pF 对信号完整性的影响,必要时采用低电容型 TVS 或在设计中加入串联阻抗/滤波以匹配信号带宽。
  • 对于易受大浪涌影响的线路,可在 TVS 前加串联限流电阻或配合熔断/电流限制元件,提高系统的整体耐受能力。
  • 焊接/回流过程按 DFN1006-2L 推荐工艺执行,避免过热导致器件参数漂移。

六、注意事项

  • 钳位电压 10 V 为典型值,在不同脉冲幅值和测量条件下会有变化,设计时应留有足够的安全裕量。
  • 双向器件不适合需要单向偏置的电源轨保护(比如严格的单向 5 V 电源),应根据具体应用选择合适极性。
  • 若系统对电容负载极为敏感,建议先做信号完整性测试再确定是否采用本型号。

ESD56031N-2/TR 提供了在有限空间内对常见静电与浪涌威胁的可靠保护,适合嵌入式与接口密集型产品,但在高速/低容忍场合应结合实际测试评估其结电容对信号的影响。

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
