ESD73031N-2/TR 产品概述
一、概述
ESD73031N-2/TR 是 WILLSEMI（韦尔）推出的一款单路双向超低电容瞬态电压抑制器（TVS），专为高速度信号和敏感接口的静电（ESD）与浪涌保护设计。器件以 DFN1006-2L 小型封装提供，结合极低结电容（Cj = 0.8 pF）与可靠的脉冲防护能力，能够在不影响信号完整性的前提下，保护系统免受静电放电与雷击类瞬态干扰。
二、主要参数与特性
- 类型：TVS 二极管，1-Line，双向（Bi-directional）。
- 钳位电压（Vc）：9 V（典型条件下）。
- 击穿电压（Vbr）：7 V。
- 反向工作峰值电压（Vrwm）：5 V。
- 峰值脉冲电流（Ipp）：11 A @ 8/20 μs。
- 反向漏电流（Ir）：1 nA（典型）。
- 结电容（Cj）：0.8 pF（极低电容，适合高速信号）。
- 通道数：单路。
- 防护等级：符合 IEC 61000-4-2（静电放电）与 IEC 61000-4-5（雷击/浪涌）标准。
- 封装：DFN1006-2L，便于高密度 PCB 布局。
这些参数使得 ESD73031N-2/TR 在保护高速数据线（如 USB、HDMI、LVDS、MIPI、SATA 等）时，能在保证信号完整性与低插入损耗的同时提供有效的浪涌及静电防护。
三、典型应用场景
- 消费电子高速接口保护（手机、平板、相机等）。
- 通信设备与网络端口的静电及浪涌防护。
- 工业控制与传感器接口，尤其要求低电容和高抗干扰能力的场合。
- 车载信息娱乐与辅助驾驶接口（需考虑额外的车规认证时）。
- 任意需要将信号线直接暴露于外部环境并要求高可靠防护的设备。
四、封装与布局建议
- DFN1006-2L 封装占位小，建议将器件尽量靠近需要保护的连接器或测试点放置，以缩短保护回路。
- 使用短而宽的走线连接到接地平面，必要时增加单点接地或低感抗接地结构以提升效果。
- 避免在保护器件到保护点之间穿过敏感高速阻抗走线，减少多余的串联电感与寄生耦合。
- 对于双向器件，无需额外极性考虑，直接并联于被保护信号与地之间。
五、可靠性与合规
ESD73031N-2/TR 满足 IEC 61000-4-2 与 IEC 61000-4-5 的测试要求，能承受工业和消费环境下常见的静电冲击与浪涌事件。器件具有极低漏电与稳定的击穿特性，适合长期可靠工作。
六、订购信息与注意事项
型号：ESD73031N-2/TR；品牌：WILLSEMI（韦尔）；封装：DFN1006-2L。
选型时请确认系统最高工作电压不超过 Vrwm（5 V），并评估 8/20 μs 浪涌电流（11 A）是否满足应用场景要求。若用于车规或更高浪涌等级场合，请咨询供应商以获取对应认证或更高规格产品。
如需样品参数曲线、封装尺寸图或参考电路图，可联系供应商技术支持以获得详细资料。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
