LESD5D5.0CT1G 产品概述

一、产品简介

LESD5D5.0CT1G 是友台半导体(UMW)推出的一款低容量、低钳位电压的瞬态抑制二极管(TVS),封装为超小型 SOD-523。器件针对 5V 及低电压数字/模拟接口提供静电(ESD)和瞬态浪涌(EFT/浪涌)保护,满足 IEC 61000-4-2(静电放电)与 IEC 61000-4-4(快速瞬变脉冲群)等抗扰度要求。

二、主要电气参数

  • 反向工作电压 Vrwm:5V(适用于 5V 电源/信号线)
  • 击穿电压(Vbr):典型 7.8V
  • 钳位电压(Vclamp):18.6V(在 Ipp 条件下)
  • 峰值脉冲电流 Ipp:9.4A(8/20µs 波形)
  • 结电容 Cj:15pF(适合高速信号线)
  • 反向漏电流 Ir:1µA(在 Vrwm 下)
  • 工作温度范围:-40℃ ~ +125℃

三、核心特性与优势

  • 小型 SOD-523 封装,适合高密度 PCB 布局与自动贴装。
  • 低结电容(15pF),对高速通信线路干扰小,兼顾信号完整性。
  • 低漏电流,适用于对静态功耗敏感的移动和便携设备。
  • 钳位电压可有效限制高能瞬态,保护下游 IC 免受损坏。

四、典型应用场景

  • USB、HDMI、Ethernet 等 5V 信号接口的 ESD/EFT 保护。
  • 智能手机、平板、笔记本等便携终端外部接口保护。
  • 工业控制模块、通讯设备和汽车电子(非车规级环境)中的低压保护。

五、设计与布局建议

  • 将 TVS 靠近需保护的接口引脚放置,最短走线连接到地。
  • 使用固体地平面并设置良好回流路径,减少环路电感。
  • 对于差分或高速线,可考虑与串联阻抗(如小电阻或磁珠)配合使用,以改善吸收性能并抑制反射。
  • 在高温或高能量环境中评估多颗并联或更高 Ipp 等级的器件以满足可靠性要求。

总结:LESD5D5.0CT1G 以其小封装、低容、低漏电和较高的脉冲承受能力,适合在空间受限且对信号完整性有要求的 5V 接口提供高效的瞬态保护。

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
