ESD73131CZ-2/TR 产品概述

一、简介

ESD73131CZ-2/TR 是 WILLSEMI(韦尔)推出的一款高性能双向瞬态电压抑制(TVS)二极管,专为保护 5V 电平高速信号线与接口免受静电放电(ESD)与雷电浪涌(浪涌)侵害而设计。器件具有极低结电容(Cj = 0.3 pF)、小体积封装(DWN0603-2L),适合对信号完整性要求高的便携设备和通信接口保护。

二、主要参数

  • 极性:双向
  • 反向截止电压 (Vrwm):5 V
  • 钳位电压 (Vc):6.5 V(典型)
  • 峰值脉冲电流 (Ipp):13 A @ 8/20 μs
  • 峰值脉冲功率 (Ppp):78 W @ 8/20 μs
  • 击穿电压 (Vbr):12.5 V
  • 反向漏电流 (Ir):1 μA
  • 通道数:单路
  • 工作温度:-40 ℃ ~ +85 ℃
  • 防护等级:符合 IEC 61000-4-5(浪涌)与 IEC 61000-4-2(静电放电)
  • 类型:TVS
  • 结电容:0.3 pF
  • 封装:DWN0603-2L

三、产品特点

  • 低结电容(0.3 pF),对高速差分和单端信号(如 USB、HDMI、SATA)影响极小,保证信号完整性。
  • 双向结构,可在正负瞬态电压下工作,适用于差分对或双向数据线保护。
  • 高频、低串扰:小封装与低寄生参数,有利于高速 PCB 布局。
  • 强抗浪涌能力:13 A @ 8/20 μs 的冲击电流和 78 W 峰值功率,能应对常见浪涌事件。
  • 低漏电流(1 μA),适合对待机功耗敏感的便携产品。

四、典型应用

  • USB、Type-C、HDMI、DisplayPort 接口过压/ESD 保护
  • 手机、平板、笔记本等消费电子外部接口保护
  • 工业通信接口与控制信号保护
  • 摄像头、传感器数据线保护等需低电容、高速传输场合

五、应用建议与 PCB 布局要点

  • 器件应尽可能靠近受保护端口或连接器放置,信号线到 TVS 的走线尽量短且宽以降低感抗。
  • 将接地面做成连续的低阻抗接地层,TVS 的地端通过较直接的回流路径连接到系统地。
  • 对于差分对,双向 TVS 可并联在两根线之间或线对对地具体取决于保护策略;确保不影响差分阻抗匹配。
  • 在高频应用中避免邻近大面积焊盘或长回流路径,以免增加寄生电容和感抗。
  • 考虑焊盘尺寸与回流可制造性,参考 DWN0603-2L 的推荐 PCB 尺寸和焊盘设计。

六、可靠性与合规

ESD73131CZ-2/TR 通过 IEC 61000-4-2 与 IEC 61000-4-5 等抗扰度规范测试,适合要求抗静电与抗浪涌的民用及部分工业应用。实际设计中仍需根据系统电源与接地策略进行整体防护评估。

七、封装与订购信息

  • 封装:DWN0603-2L(超小型 0603 等效)
  • 描述:瞬态抑制二极管 ESD73131CZ-2/TR
  • 品牌:WILLSEMI(韦尔)

本器件凭借低电容、高浪涌能力与小封装,适合用于对信号完整性与抗扰度有严格要求的 5V 接口保护场景。设计时请结合实际系统电磁兼容(EMC)需求与 PCB 布局规范进行验证。

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
