UDD32C05L01 产品概述

一、产品简介

UDD32C05L01 是 FUXINSEMI(富芯森美)推出的一款双路双向低电容瞬态电压抑制(TVS)二极管,专为高速数据线及低电压接口的静电放电(ESD)与浪涌保护设计。器件采用 SOD-323(SC-90)小型表面贴装封装,尺寸紧凑,适合空间受限的移动终端、通讯设备及消费电子产品。

二、主要参数

  • 极性:双向(Bidirectional)
  • 反向工作电压 Vrwm:5 V
  • 击穿电压(Vz / 起始击穿):约 8 V
  • 钳位电压(Vc):20 V(典型钳位)
  • 峰值脉冲电流 Ipp:18 A
  • 峰值脉冲功率 Ppp:360 W(脉冲测试条件下)
  • 反向电流 Ir:≤1 μA
  • 结电容 Cj:0.6 pF(低电容,利于高速信号)
  • 通道数:双路独立保护
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 防护等级/标准:满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)要求
  • 封装:SOD-323 (SC-90)

三、关键特性

  1. 双向保护,适用于需双向瞬态保护的数据通道或差分对。
  2. 低结电容(0.6 pF),对信号完整性影响小,适合 USB、UART、I2C 等高速/高频接口。
  3. 低漏电流(≤1 μA),在待机或低功耗场景下不会显著增加功耗。
  4. 高峰值脉冲功率与电流能力(360 W / 18 A),能应对常见 ESD 与浪涌事件。
  5. 小型 SOD-323 封装,便于在空间受限的 PCB 上紧靠接口布局。

四、典型应用场景

  • USB2.0/USB3.0 下游/上游端口(5 V 系统)
  • 手机、平板与便携式设备的数据接口保护
  • 串口(UART/RS-232 可选)、I2C、SPI 低压信号线
  • 摄像头、显示器接口及其他需要低电容保护的高速差分信号线
  • 工业及通信设备的接口防护,满足 IEC 61000-4-2/4-5 标准要求

五、设计与布板建议

  • 将 UDD32C05L01 尽量靠近外部连接器或易受静电侵害的接口放置,缩短 PCB 走线长度以降低感应噪声与钳位延迟。
  • 对于差分或双通道信号,分别为每路使用独立器件或按器件推荐连接方式布线,确保双向钳位性能。
  • 在进行高速信号线保护时,低结电容优势明显,但仍需在 PCB 布局上控制阻抗连续性与回流路径。
  • 遵循制造商的焊接与回流曲线规范,避免超出封装可承受的温度循环。

六、可靠性与合规

UDD32C05L01 针对 ESD(IEC 61000-4-2)与浪涌(IEC 61000-4-5)进行了性能设计与验证,适用于需要通过相关抗扰度测试的产品。器件工作温度范围宽,适合多种应用环境。为保证长期可靠性,建议在系统级进行必要的整机抗扰度测试与验证。

七、包装与订购信息

  • 品牌:FUXINSEMI(富芯森美)
  • 型号:UDD32C05L01
  • 封装:SOD-323 (SC-90);适合自动贴装与小型化设计。
    在选型与采购时,请向供应商索取最新的数据手册与器件测试报告,以获得更详细的电气特性曲线、测试条件和封装尺寸信息。若有高能级浪涌或特殊应用需求,建议与厂商技术支持沟通以确认器件的适用性与可替代方案。

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
