ESD54151N-2/TR 产品概述

一、产品简介

ESD54151N-2/TR 是韦尔(WILLSEMI)推出的一款双向瞬态电压抑制器(TVS/ESD)器件,专为接口静电放电(ESD)、电快速瞬变(EFT)和浪涌(Surge)保护设计。器件以小型 DFN1006-2 封装提供,适合空间受限的消费类与工业类电子设备,用于保护 I/O 接口和敏感信号线免受瞬态过电压损害。

二、主要电气参数

  • 钳位电压(VCL):11.5 V(典型)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 击穿电压(Vbr):6.1 V
  • 反向截止电压(Vrwm / standoff):5.5 V(适配 5 V 系统)
  • 峰值脉冲功率(Ppp):90 W @ 8/20 μs
  • 峰值脉冲电流(Ipp):8 A @ 8/20 μs
  • 结电容(Cj):17.5 pF
  • 反向电流(Ir):1 nA(典型,低泄漏)
  • 极性:双向(Bidirectional)
  • 符合标准:IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(Surge)
  • 类型:ESD/浪涌保护器件
  • 封装:DFN1006-2,包装形式:TR(Tape & Reel)

三、特性与优势

  • 双向保护:支持正反向瞬态,适用于差分信号或无固定极性的接口(如双向数据线)。
  • 5.5 V 工况适配:Vrwm=5.5 V 使其可直接用于 5 V 系统的边缘保护,应对电源或信号线上意外过压情况。
  • 高能量吸收能力:90 W(8/20 μs)和 8 A 峰值脉冲电流,能够吸收典型线路级浪涌或较强的静电脉冲。
  • 低泄漏电流:Ir≈1 nA,有利于降低静态功耗与不影响精密模拟/ADC 输入。
  • 小体积封装:DFN1006-2 占板面积小,适合高密度 PCB 布局。
  • 工业级温度范围:-40 ℃ 至 +85 ℃,可在多数商业与工业环境中稳定工作。
  • 符合多项 IEC 抗扰标准:便于满足产品 EMC 设计要求,提高系统可靠性和认证通过率。

四、典型应用场景

  • USB、HDMI、MIPI、串行接口(UART、RS-232/485)等外围接口的过压/ESD 保护。
  • 手机、平板、笔记本等消费电子设备的外部连线保护。
  • 工业控制、仪表和网络设备的信号线防护。
  • 视频、音频链路及通用数字接口的瞬态抑制。

五、封装与PCB布局建议

  • 尽量靠近需要保护的连接器或器件放置 TVS 器件,使引线短且直,减少回路电感和寄生阻抗。
  • GND 端应采用完整的地平面或多层回流,保证高电流脉冲时的低阻抗路径。
  • 对高速差分信号,评估 17.5 pF 的结电容对信号完整性的影响;必要时在布局和信号链上进行仿真验证。
  • 使用制造商推荐的 PCB 封装尺寸与焊盘布局,注意热沉和可焊性控制。

六、选型与注意事项

  • 若目标为高速接口(如 USB3.0、PCIe 等)或对带宽要求极高的信号线,应评估器件 17.5 pF 的影响,必要时选用更低电容的 TVS。
  • 工作温度上限为 +85 ℃,若应用在高温环境(如部分汽车场景)需选择更高温规格或汽车级产品。
  • 钳位电压 11.5 V 为典型值,实际钳位随冲击电流变化,应根据系统允许的最大电压和器件承受能力进行核算。
  • 关注焊接工艺和回流曲线,以免损伤小封装器件。

总结:ESD54151N-2/TR 以其小尺寸、双向保护、低泄漏和较高的脉冲能量承受能力,适合用作 5 V 系统与一般 I/O 接口的静电与浪涌保护器件。在高速或更严苛温度环境下,请结合结电容和温度参数进行评估与验证。

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
