WILLSEMI ESD56241D24-3/TR 产品概述

一、产品简介

ESD56241D24-3/TR 是 WILLSEMI(韦尔)推出的一款单路单向瞬态抑制器(TVS),封装为 DFN2x2-3L,专为对抗静电放电和雷击浪涌等瞬态过压事件设计。该器件反向截止电压(Vrwm)为 24V,击穿电压为 27.3V,钳位电压约为 39V(在 Ipp=120A、8/20μs 测试条件下),峰值脉冲吸收能力 Ipp 达到 120A(8/20μs),反向漏电流仅 100nA,结电容 Cj 为 800pF,工作温度范围 -40℃ 至 +85℃。符合 IEC 61000-4-5 防护等级,适用于对电源线或接口线的过压保护。

二、主要电气参数解读

  • Vrwm = 24V:常态系统电压建议不超过此值,适合 24V 类电源或接口保护。
  • Vbr = 27.3V:器件进入雪崩击穿的电压区间,略高于 Vrwm,确保正常工作下不触发。
  • 钳位电压 ≈ 39V @ Ipp=120A:在极限脉冲时能将瞬态电压钳制到约 39V,保护下游电路免受高压冲击。
  • Ipp = 120A(8/20μs):短时大电流吸收能力强,可抵抗雷击浪涌或开关瞬态。
  • Cj = 800pF:较大的结电容,会对高速差分信号或高频接口造成影响,宜用于电源线或低速信号线保护。
  • Ir = 100nA:低漏电适合电池及低功耗系统,减少静态能源损耗。

三、典型应用场景

  • 24V 电源总线保护(工业控制、楼宇自控)。
  • 电源输入、充电口、适配器接口的浪涌抑制。
  • 需要 IEC 61000-4-5 等级浪涌防护的设备。
  • 低速或模拟信号线路保护(注意结电容带来的影响),不推荐用于超高速数据线(如 USB3.0、PCIe 等)。

四、PCB 布局与使用建议

  • 将器件尽量靠近受保护的连接器或接口放置,以缩短引线寄生感抗。
  • 将管脚接地(阴极/阳极取决于单向接法)直接引到大面积接地平面,必要时使用多颗地 vias 提高散热与回流路径。
  • 对于高能脉冲,可在 TVS 前增加熔断器、限流电阻或磁珠以分担能量并降低钳位电压。
  • 由于 Cj=800pF,若用于数据线应评估对信号完整性的影响;对高速应用考虑选用低容型 TVS。
  • 焊接与回流:DFN2x2 小封装,按照厂方推荐的回流曲线和焊盘设计进行,避免过热或焊接缺陷。

五、可靠性与选型要点

  • 单向器件适用于明确极性电源线路;若应用存在双向过压,应选用双向 TVS。
  • 工作温度 -40℃~+85℃,满足一般工业级环境;如需更宽温度范围,确认器件的温度漂移与老化特性。
  • 关注钳位电压与被保护器件的耐压裕度,确保在最大冲击下下游元件不会被破坏。
  • 订购信息:型号 ESD56241D24-3/TR,封装 DFN2x2-3L,常见为带卷装(Tape & Reel)出货。

总结:ESD56241D24-3/TR 提供了针对 24V 级电源与低速信号的强力瞬态抑制能力,峰值吸收 120A(8/20μs)且钳位约 39V,封装小巧适合空间受限应用。选型时需综合考虑结电容对信号的影响、系统最大允许电压与 PCB 布局,以达到最佳防护效果。若需要更详细的封装焊盘、热阻及回流信息,请参阅 WILLSEMI 官方数据手册。

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
