ESD56371N-2/TR 产品概述

一、产品简介

ESD56371N-2/TR 是 WILLSEMI(韦尔)推出的一款双向瞬态电压抑制器(TVS),用于静电放电(ESD)和雷击/浪涌(Surge)保护。器件封装为小型 DFN1006-2L,适合空间受限的高密度电路板设计,产品以卷带(TR)形式供货,便于量产贴装。

二、主要电气参数

  • 类型:TVS(二极管,双向)
  • 反向截止电压 Vrwm:15 V
  • 击穿电压(典型):16 V
  • 钳位电压:21.5 V
  • 峰值脉冲功率 Ppp:470 W(标准 8/20 μs 浪涌波形)
  • 峰值脉冲电流 Ipp:22 A(8/20 μs)
  • 结电容 Cj:31 pF
  • 反向漏电流 Ir:1 nA
  • 工作温度范围:-40 °C ~ +85 °C
  • 防护等级:符合 IEC 61000-4-5(浪涌)和 IEC 61000-4-2(静电放电)标准

三、产品特性与优势

  • 高能量吸收能力:470 W(8/20 μs)与 22 A 峰值冲击电流能有效钳位中等级别的浪涌,适用于工业和通信接口的浪涌防护。
  • 双向保护:适合双向信号线或对称电源保护,无需额外极性判断。
  • 低漏电:1 nA 的反向漏电流有利于在待机或高阻抗输入处保持系统稳定。
  • 小体积封装:DFN1006-2L 便于贴片,适合便携设备与高密度板面设计。
  • 符合国际浪涌与静电标准:通过 IEC 61000-4-2/4-5 测试认证,提升系统电磁兼容可靠性。

四、典型应用场景

  • 工业控制接口、现场总线保护
  • 通信设备接口线(如 RS 系列、低速数据线)
  • 终端设备的电源线上浪涌防护(适用于最大工作电压约 15 V 的场合)
  • 人机接口/按键、接口板卡的静电保护

五、设计与布局建议

  • 放置位置:尽量靠近被保护的接口或引脚,优先放在信号进入 PCB 的第一点。
  • 接地处理:使用短且低阻抗的接地路径,避免通过长回路泄放能量。
  • 焊盘与散热:DFN1006-2L 的焊盘应按照厂家推荐的 land pattern 布局,保证良好焊接与热能分散。
  • 高频影响:31 pF 的结电容在某些高速差分信号上会引起回波或带宽下降,关键高速接口请评估容值对信号完整性的影响,必要时选择低容型 TVS。

六、选型提示

  • 若系统工作电压接近或高于 15 V,应检查 Vrwm 与工作裕度;若需更高 Vrwm,请选用对应更高反向截止电压的器件。
  • 对于高速数据线(如 USB 3.x、PCIe 等),建议选用低结电容(<5 pF)型号以减少信号畸变。
  • 对于需要更高环境温度或汽车级应用,应选择对应温度等级与 AEC-Q 规范认证的 TVS 器件。

七、包装与可靠性

ESD56371N-2/TR 提供卷带(Tape & Reel)包装,适合自动贴片生产。产品通过 IEC 61000-4-2 和 IEC 61000-4-5 等电磁兼容测试,长期工作温度范围 -40 ℃ 至 +85 ℃,适用大多数工业和消费类终端环境。

以上为 ESD56371N-2/TR 的概述与实用参考,具体电气参数、封装尺寸及 PCB land pattern 请参考 WILLSEMI 官方数据手册,以获得完整的应用资料与可靠性信息。

Sourcing availability signal

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
