ESD56241D22-3/TR 产品概述

一、产品简介

ESD56241D22-3/TR 是 WILLSEMI(韦尔)推出的一款单路单向 TVS(瞬态电压抑制)二极管,采用 DFN2x2-3L 小型表贴封装,专为承受工业级浪涌和静电放电事件设计。该器件满足 IEC 61000-4-5 防护等级,能够在 8/20 μs 浪涌波形下提供高达 130 A 的峰值脉冲电流和 4.5 kW 的峰值脉冲功率,适合电源输入、工业控制与通信接口等需要浪涌保护的场合。

二、核心电气参数

  • 极性:单向(Unidirectional)
  • 反向工作电压 Vrwm:22 V
  • 击穿电压 Vbr:25 V(典型)
  • 钳位电压 Vc:38 V(在 8/20 μs、Ipp=130 A 条件下)
  • 峰值脉冲电流 Ipp:130 A @ 8/20 μs
  • 峰值脉冲功率 Ppp:4.5 kW @ 8/20 μs
  • 反向漏电流 Ir:100 nA(常温)
  • 结电容 Cj:900 pF
  • 通道数:单路
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 防护标准:符合 IEC 61000-4-5
  • 封装:DFN2x2-3L(小型 SMD)
  • 品牌:WILLSEMI(韦尔)
  • 型号:ESD56241D22-3/TR

三、主要性能亮点

  • 高浪涌承受能力:在标准 8/20 μs 浪涌测试波形下,ESD56241D22-3/TR 能承受 130 A 峰值脉冲电流并将瞬态能量限制在安全电压范围内,适合直接保护电源线和高能冲击源。
  • 有效钳位:在大浪涌时钳位电压约 38 V(典型),能将瞬态电压限制,保护下游器件免受过压损害。
  • 低漏电流:反向漏电仅约 100 nA,适合对静态功耗敏感的应用。
  • 小型封装:DFN2x2-3L 占板面积小,便于对空间受限的电子产品进行表面贴装保护。
  • 工业级温度范围:-40 ℃ 到 +85 ℃,满足多数工业和民用场景的温度需求。

四、适用场景与推荐应用

  • 工业电源输入保护(尤其是 12 V ~ 24 V 系统的输入端防浪涌)
  • 电源适配器与开关电源初级或次级防护
  • 通信基站、远程终端单元(RTU)及 PLC 的电源与接口保护
  • 家电与楼宇自动化中的浪涌抑制点
  • 非高速数据线的 EMI / ESD 保护(注意结电容较大,见下文)

五、设计与布局建议

  • 引脚与散热:DFN2x2-3L 具备中心焊盘或接地焊盘,建议将中心焊盘可靠焊接并与系统地(GND)良好连接,以确保最佳浪涌能量分散与热流输出。
  • 布线最短化:将 TVS 与被保护的电源/信号引脚之间走线尽可能缩短,以降低串阻和感抗,从而提高钳制效率。
  • 地回流路径:为保证吸收大电流时的性能,PCB 上应提供低阻抗、宽回流路径到系统接地,必要时使用多层过孔加固散热和电流路径。
  • 焊接工艺:按行业通用回流焊温度曲线进行焊接,避免超出厂商推荐的温度峰值,以免影响器件特性与可靠性。
  • 结电容考量:器件结电容约 900 pF,信息传输或高速信号线若对带宽敏感(如 USB/高速串行总线)不建议直接使用;该特性适合电源线、低速 IO 或对滤波有利的场合。

六、可靠性与符合性

ESD56241D22-3/TR 已按 IEC 61000-4-5 定义的浪涌测试进行设计与验证,能满足工业级浪涌保护要求。工作温度范围及低漏电流使其在长期工作中保持稳定性能。为确保长期可靠性,建议在系统级通过实际环境测试(温度循环、功率循环、浪涌重复测试)验证整体保护方案。

七、封装与订购信息

  • 封装形式:DFN2x2-3L,便于自动化贴装与高密度 PCB 设计
  • 备注:订货型号 ESD56241D22-3/TR,具体包装卷盘尺寸与出货管控请参考 WILLSEMI 官方数据手册与订购信息

八、结论

ESD56241D22-3/TR 是一款面向工业电源与低频接口的高能浪涌保护 TVS 器件,其 130 A/8/20 μs 的抗浪涌能力、38 V 的钳位表现以及 DFN2x2 小封装,使其在空间受限的电源入口与工业设备中具有较高的实用性。设计时需注意其较大的结电容对高速信号的影响,并在 PCB 布局、接地与散热方面采取相应优化措施,以发挥最佳保护效果。

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.
