ESD5641D10-3/TR 产品概述

一、产品简介

ESD5641D10-3/TR 是 WILLSEMI(韦尔)推出的一款单路单向 TVS 晶片,用于对抗瞬态过压和浪涌冲击。器件采用小型 DFN2x2-3L 封装,专为需要高浪涌抑制能力和低泄漏、高可靠性保护的电路设计。其主要目标是保护电源线、接口及其它敏感节点免受静电放电(ESD)、雷击或开关瞬变造成的损坏,符合 IEC 61000-4-5 防护等级要求。

二、关键参数

  • 钳位电压(VC):23 V(在指定脉冲条件下)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 击穿电压(Vbr):13.5 V
  • 反向截止电压(Vrwm):10 V
  • 峰值脉冲电流(Ipp):170 A @ 8/20 µs
  • 反向电流(Ir):1 nA(常态低泄漏)
  • 结电容(Cj):1500 pF
  • 通道数:单路;极性:单向
  • 类型:TVS;封装:DFN2x2-3L;符合 IEC 61000-4-5

三、主要特性与优势

  • 高能量吸收:170 A(8/20 µs)峰值能力,能有效吸收工业级浪涌与雷击脉冲。
  • 低钳位:在大电流冲击下钳位电压约 23 V,可保护后端器件免受过压。
  • 低泄漏:1 nA 级反向电流,有利于低功耗系统长期稳定运行。
  • 小型封装:DFN2x2-3L 占板面积小,适合空间受限的便携设备与终端设备。
  • 工业级温度:支持 -40 ~ +85 ℃,可在常见工业环境中可靠工作。
  • 高结电容:1500 pF 对于需要滤波或抗干扰的线路有利,但对高速差分信号需评估影响。

四、典型应用场景

  • 电源线防护:5 V / 9 V 等低压电源输入的浪涌与突波抑制(注意 Vrwm=10 V 的额定)。
  • 通讯与控制接口:如低速 UART、GPIO、音频线路等需要耐受浪涌保护的场合。
  • 工业终端设备、智能家电、车载辅件(非关键动力系统)等需抗干扰与雷电保护的电子模块。
  • ESD 与浪涌并存的系统入口点,搭配滤波与逆保护电路使用。

五、设计与选型建议

  • Vrwm=10 V 及 Vbr ≈13.5 V 表明器件适用于不超过 10 V 常态工作电压的系统;若系统工作电压高于此范围,应选用更高 Vrwm 的型号。
  • 结电容 1500 pF 较大,对高速信号(如 USB3.0、高速差分总线)会产生明显的信号完整性影响,建议用于电源线或低速/单端信号保护,不宜直接用于高速差分对。
  • 钳位电压 23 V 在大冲击下仍能维持较低电压峰值,适合保护后端敏感器件,但需确认被保护电路允许短时间承受该电压峰值。
  • 为发挥最佳保护效果,TVS 引脚到 PCB 地的连接应尽量短且宽,采用单股或单孔接地并靠近保护点布置。

六、封装与安装注意

  • DFN2x2-3L 小型表面贴装,焊接工艺遵循无铅回流曲线;焊盘设计建议参考厂家封装资料以保证热可靠性与焊点质量。
  • PCB 布局建议:尽量缩短保护器件至被保护节点与地之间的回流路径,地端使用单点或局部大地铜箔以降低接地阻抗。
  • 温升与可靠性:在频繁或多次大电流脉冲环境下需关注器件热耗散与 PCB 热设计,避免超出器件热极限。

七、总结

ESD5641D10-3/TR 提供了小封装下的高浪涌能量吸收能力和低泄漏特性,适合为低压电源与低速信号提供工业级浪涌与 ESD 保护。在选型时需注意 Vrwm 与结电容对目标电路工作电压和信号完整性的影响,配合合理的 PCB 布局与接地设计,可在多种终端设备中实现可靠的瞬态过压防护。若需更高工作电压或更低结电容的保护方案,建议查看同系列或相近规格的其他型号。

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.
