NUP4114HMR6T1G 产品概述

一、产品简介

NUP4114HMR6T1G 是东沃(DOWO)推出的一款四路单向瞬态抑制器(ESD protector),采用 SOT-23-6L 封装,专为 5V 系统的瞬态过压、浪涌和静电放电保护设计。器件集成四路保护通道,具有单向钳位特性,适用于对严格信号完整性和低漏电要求的接口保护场景。

二、主要电气参数

  • 极性:单向
  • 反向截止电压 Vrwm:5 V(适配典型 5V 总线/电源)
  • 击穿电压 VBR:6 V
  • 钳位电压(典型):15 V
  • 峰值脉冲电流 Ipp:4.5 A @ 8/20 μs
  • 峰值脉冲功率 Ppp:60 W @ 8/20 μs
  • 反向电流 Ir:1 μA(高阻态、低漏电)
  • 结电容 Cj:0.3 pF(对高速信号影响极小)
  • 通道数:4 路
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 符合标准:IEC 61000-4-5(浪涌)、IEC 61000-4-2(ESD)

三、主要特性与优势

  • 单向保护,优先钳制正向瞬态,适合 5V 电源和 I/O 线保护。
  • 低结电容 0.3 pF,适合高速信号(如 USB、UART、I2C 等)而不显著降低信号完整性。
  • 高脉冲能量吸收能力(Ipp 4.5 A / Ppp 60 W)可承受典型浪涌与脉冲冲击。
  • 极低反向电流(1 μA),在待机或低功耗系统中影响微小。
  • 宽温度范围和工业级可靠性,适用于车载、工业与消费电子产品。

四、典型应用场景

  • 5V 系统电源线与数据线保护(USB、外设接口、电源输入等)。
  • 高速通讯接口(需低电容保护的 I/O 总线)。
  • 工业控制、自动化设备的端口防护。
  • 需满足 IEC-ESD/Surge 要求的产品设计。

五、PCB 布局与选用建议

  • 将器件尽可能靠近受保护的连接器或接口放置,缩短信号/电源走线长度以提高抑制效果。
  • 保护器地线应短且直;如有多层板,建议通过平面或多条过孔回到共同接地平面。
  • 对于特别敏感的信号,可在保护器前并联小阻值或配合串联阻抗以分配能量。
  • 注意器件为单向,确保电路方向与保护极性一致;对双向需求请选用对应型号。
  • 校验钳位电压(15 V)是否满足后级器件耐压要求,必要时加器件级联或限流设计。

六、封装与订购信息

  • 品牌:DOWO(东沃)
  • 型号:NUP4114HMR6T1G
  • 封装:SOT-23-6L,适合高密度表贴设计与自动化生产。
  • 建议在 BOM 中标注完整型号与封装以便采购与替换。

本器件以其四路集成、低电容和良好的脉冲吸收能力,适合要求高可靠性与信号完整性的 5V 接口保护场合。选择与布局得当时,能显著提升产品的抗静电与浪涌能力,降低现场失效率。

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
