UDT26A05L05 四路低容抗浪涌TVS(Leiditech 雷卯电子)

一、产品简介

UDT26A05L05 是雷卯电子(Leiditech)推出的一款四路瞬态抑制器(TVS),面向 5V 工作电压系统的过压、浪涌和静电放电保护需求。器件以 SOT-26 小封装集成四通道保护单元,具有低结电容(Cj≈0.5pF)、低漏电(Ir≈1µA)和宽工作温度范围(-55℃ ~ +125℃),并符合 IEC 61000-4-2/4-4/4-5 等电磁兼容防护标准,非常适合便携设备和高速信号线的防护应用。

二、主要特点

  • 反向截止电压(Vrwm):5V,适用于 5V 电源与 I/O 线保护
  • 击穿电压:约 6V,工作点稳定可靠
  • 峰值脉冲功率(Ppp):350W(8/20µs),对浪涌冲击有良好吸收能力
  • 钳位电压:在不同测试电流下典型为 15V ~ 28V(随测试条件而异),有效限制过压幅值
  • 低结电容:Cj ≈ 0.5pF,适合高速差分/单端信号线,不影响信号完整性
  • 低漏电流:Ir ≈ 1µA,降低静态功耗
  • 四路通道设计,节省 PCB 空间并降低器件数量
  • 小型 SOT-26 封装,便于自动贴装与紧凑布局

三、电气和环境参数概览

  • 类型:TVS(瞬态电压抑制二极管)
  • 工作电压(Vrwm):5V
  • 击穿电压:6V(典型)
  • 钳位电压:15V / 28V(取决于测试电流与条件)
  • 峰值脉冲功率:350W @ 8/20µs
  • 反向漏电流(Ir):1µA(典型)
  • 结电容(Cj):0.5pF(典型)
  • 通道数:4 路
  • 工作温度:-55℃ ~ +125℃
  • 抗扰标准:符合 IEC 61000-4-2(ESD)、IEC 61000-4-4(EFT)、IEC 61000-4-5(浪涌)

四、封装与可靠性

UDT26A05L05 采用 SOT-26 表面贴装封装,体积小、焊点可靠,适合高密度电路板设计。器件经过高低温循环及静电抗扰试验,能在工业级温度范围内长期稳定工作,符合常见 EMC/ESD 测试要求,适用于消费电子、工业控制等多种场景。

五、典型应用场景

  • USB/串口/通用 I/O 保护(5V 系统)
  • 手机、平板、笔记本等便携终端的信号线与供电防护
  • 工业控制、仪表的接口浪涌与 ESD 防护
  • 摄像头模块、传感器接口与高速通信线路的瞬态抑制

六、PCB 布局与使用建议

  • 将 TVS 尽量靠近被保护接口焊盘放置,以缩短走线并降低感性耦合。
  • 每路保护端应尽量直接连至地线,并用粗短过孔或铜皮连接至公共地,减少回路阻抗。
  • 对高速差分信号,保持等长走线并注意终端阻抗匹配,利用低电容特性可降低对信号的影响。
  • 对于强烈浪涌环境,可在输入端配合熔断器或多级保护电路以分担能量。

七、选型与订购建议

UDT26A05L05 适合需要四路、低容、5V 工作电压保护的小体积应用场合。购买时请确认所需的钳位性能(随浪涌电流不同钳位电压会变化)以及是否需要单向或双向 TVS(本型号以 5V 单端工作电压为参考)。品牌:Leiditech(雷卯电子);封装:SOT-26。若需器件数据手册、浪涌测试曲线或样品支持,可联系雷卯电子技术支持获取详细规范与应用参考电路。

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
