ESD5311N 产品概述

一、概览

ESD5311N 是 TECH PUBLIC(台舟电子)推出的一款单通道双向 ESD 二极管,采用微型 DFN1006-2 封装,专为高速接口与低电压系统提供静电放电(ESD)与浪涌保护而设计。器件在保持极低结电容的同时,具备符合 IEC 61000-4-2 和 IEC 61000-4-5 标准的防护能力,适用于移动终端、数据线接口和各类敏感 I/O 口的表面安装防护。

二、主要参数

  • 钳位电压(Vc):15 V(典型)
  • 击穿电压(Vbr):7.5 V
  • 反向截止电压(Vrwm):5 V(建议工作电压)
  • 峰值脉冲功率(Ppp):70 W
  • 峰值脉冲电流(Ipp):4 A
  • 反向漏电流(Ir):80 nA(在 Vrwm 条件下)
  • 结电容(Cj):0.3 pF(典型)
  • 通道数:单路
  • 极性:双向
  • 类型:ESD 二极管
  • 封装:DFN1006-2(1.0 × 0.6 mm)
  • 品牌:TECH PUBLIC(台舟电子)
  • 符合标准:IEC 61000-4-2 / IEC 61000-4-5

三、特性与优势

  • 极低结电容(0.3 pF):对高速信号影响极小,适合 USB、HDMI 子信号、SATA、差分对等高速数据线保护。
  • 双向保护:能有效钳位正负极性瞬态脉冲,适用于交流或双向数据线场景。
  • 小封装、高密度:DFN1006-2 占板面积小,利于移动设备与紧凑型 PCB 布局。
  • 低漏电流(80 nA):有利于电池供电设备降低待机功耗。
  • 符合工业级抑制标准:满足 IEC 61000-4-2/4-5,提升系统抗扰度。

四、典型应用

  • 手机、平板等便携终端的 I/O 接口防护(USB、耳机、调试口等)
  • 摄像头模组、高速数据链路的输入端保护
  • 工业控制与消费类电子的信号接口防雷与抗静电设计
  • 需要保持高速信号完整性的低电压数据线保护

五、设计与 PCB 布局建议

  • 位置:将 ESD5311N 尽量靠近受保护的外部连接器或接口焊盘放置,典型距离 <1 mm,以减少寄生电感与走线长度。
  • 地回流:虽为单通道双向器件,仍建议为其提供低阻抗的地回路(多层 PCB 下靠近地平面),并在器件附近布置短、粗的接地过孔。
  • 与串联元件配合:在需要更高能量吸收时,可与小阻值串联电阻或磁珠联合使用,以分担能量并减小钳位应力。
  • 热与机械:DFN1006-2 属微型封装,回流焊工艺需按推荐曲线处理,避免过热;存储与回流时注意防潮等级。

六、选型要点

  • 工作电压:若电路工作电压 ≤5 V(Vrwm = 5 V),ESD5311N 是恰当选择;对更高电压系统请确认 Vrwm 与 Vbr 满足要求。
  • 信号速率与引脚电容:0.3 pF 的超低 Cj 使其非常适合高频与差分信号,若系统对延时与失真极为敏感,此参数是关键决策因子。
  • 能量承受能力:Ppp = 70 W、Ipp = 4 A 适合常见 ESD/浪涌事件;若需抵御更大能量,应考虑并联或选用更高功率等级的保护器件。
  • 极性需求:双向器件适合无偏置或双向信号;对单向电源线保护可优先考虑单向 TVS。

七、包装与订购信息

  • 封装:DFN1006-2(适合自动贴装)
  • 型号:ESD5311N
  • 品牌:TECH PUBLIC(台舟电子)

总结:ESD5311N 在极低结电容、低漏电流和小尺寸封装的组合下,为 5 V 及以下系统和高速数据线提供高效的瞬态抑制方案。合理的 PCB 布局与配套元件能进一步提升系统的抗扰性能与长期可靠性。若需详细电气特性曲线或封装图纸,可联系供应商获取完整数据手册。

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
