NUP4202W1T2G 产品概述

一、产品简介

NUP4202W1T2G 是东沃(DOWO)推出的一款四路单向瞬态电压抑制器(TVS),针对5V工作电压系统的浪涌和静电放电保护而设计。器件采用 SOT-363 小封装,集成四路保护通道,适合空间受限的便携或板载接口保护应用。

二、主要特点

  • 单向结构,适配直流供电与信号线方向性保护。
  • 反向工作电压 Vrwm = 5V,适合典型 5V 总线(如 USB)防护。
  • 击穿电压约 8.5V,钳位电压 Vclamp ≈ 15V(峰值脉冲条件下)。
  • 峰值脉冲电流 Ipp = 4.5A(8/20µs),峰值脉冲功率 Ppp = 60W(8/20µs)。
  • 极低结电容 Cj = 0.6pF,最小化对高速信号的影响。
  • 反向漏电流 Ir = 500nA,工作温度范围 -55℃ 至 +125℃。
  • 满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)规范要求。

三、关键电气参数(摘要)

  • 类型:TVS(单向)
  • Vrwm:5V
  • 击穿电压:8.5V
  • 钳位电压:15V(典型)
  • 峰值脉冲电流:4.5A @8/20µs
  • 峰值脉冲功率:60W @8/20µs
  • 反向电流:500nA
  • 结电容:0.6pF
  • 通道数:4
  • 封装:SOT-363

四、典型应用场景

  • USB、Micro USB、Type-C 等 5V 数据/电源接口防护。
  • 移动设备、便携式仪器及消费电子的信号线与供电线防护。
  • 工业通讯接口、I/O 端口、传感器信号前端的浪涌与静电防护。
  • 需要多路小体积保护的模块化母板或接口板设计。

五、PCB 布局与使用建议

  • 将器件尽量贴近待保护的连接器或信号引脚,缩短导线长度以降低感性耦合。
  • 对于高速差分信号,注意配合阻抗控制与最小化并联电容,0.6pF 的低结电容有利于保持信号完整性。
  • 对地线采用完整接地面或短回流路径,以提升浪涌能量的散逸能力并降低钳位电压。
  • 在高能脉冲环境下,可在保护器前串联限流电阻或配合熔断器以提升系统整体鲁棒性。

六、封装与采购信息

  • 封装:SOT-363(超小型表面贴装,适合高密度 PCB 布局)。
  • 品牌:DOWO(东沃)。型号:NUP4202W1T2G。
  • 订购时注意查阅厂家数据手册以确认器件标记、回流焊工艺兼容性及批次信息。

七、可靠性与工作环境

  • 工作温度范围宽 (-55℃~+125℃),适用于大部分商用与工业等级场景。
  • 通过 IEC 61000-4-2 与 IEC 61000-4-5 等抗扰度测试,能有效抑制静电放电和浪涌事件对敏感电路的损害。
  • 推荐在实际应用中结合系统级试验验证防护效果与长期可靠性。

总结:NUP4202W1T2G 以其四通道集成、低结电容与符合 IEC 抗扰规范的能力,适合用于需要多路、低寄生、紧凑封装的5V接口与高频信号线防护场合。在布局和系统级设计时合理配合接地与限流措施,可获得更优的防护效果与信号完整性。

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
