LESD5D5.0CT1G-ES 产品概述

一、产品简介

LESD5D5.0CT1G-ES 是 ElecSuper(静芯微)推出的一款单路双向 ESD 抑制二极管,封装为 SOD523。器件针对 5V 等级的信号线与电源线提供瞬态过压保护,具有低结电容(Cj = 15 pF)、低漏电和宽工作温度范围(-40 ℃ 至 +125 ℃),适用于对信号完整性和快速响应有较高要求的应用场景。

二、主要性能特点

  • 钳位电压:典型 10 V,保证在突发脉冲时限制电压峰值,保护后端电路。
  • 反向工作电压 Vrwm:5 V,适配 5V 供电或接口系统。
  • 击穿电压(Vbr):5.8 V,器件进入钳位前的阈值电压稳定。
  • 峰值脉冲功率 Ppp:80 W(冲击条件下),提供短时大能量吸收能力。
  • 峰值脉冲电流 Ipp:8 A,能承受典型手动放电/脉冲事件。
  • 反向漏电流 Ir:1 μA,低漏电有利于节能与静态性能。
  • 结电容 Cj:15 pF,适合高速数据线应用,减小信号失真。
  • 极性:双向,单通道,安装时无需关心方向性。
  • 符合 IEC 61000-4-2 电磁兼容(ESD)防护等级要求。

三、典型电气参数(总结)

  • Vrwm:5.0 V
  • Vbr(Ibr 指定电流下):5.8 V
  • Vclamp(Ipp 下):约 10 V
  • Ipp(峰值脉冲电流):8 A
  • Ppp(脉冲功率):80 W
  • Ir(反向电流):1 μA
  • Cj(结电容):15 pF
  • 通道数:1,极性:双向
  • 工作温度:-40 ℃ ~ +125 ℃

四、封装与安装

器件采用 SOD523 小型封装,适合高密度 PCB 布局。SOD523 尺寸和焊盘推荐遵循厂方封装图与回流焊工艺规范以确保可靠焊接。双向结构使布局更灵活:直接并联于需保护的信号线上,且无方向性限制。

五、典型应用场景

  • USB、串口、GPIO 等 5V 信号接口的 ESD 防护
  • 手机、平板、便携终端的外部接口保护
  • 工业控制与物联网终端的 I/O 保护
  • 消费电子、通信设备中对高速信号与电源线的瞬态防护

六、可靠性与使用注意事项

  • 器件已按 IEC 61000-4-2 等级设计,仍建议结合系统接地与屏蔽措施以获得最佳防护效果。
  • 在反复承受高能量脉冲后器件可能衰减,关键场合建议通过系统级冗余或外部熔断保护配合使用。
  • 焊接建议遵循回流曲线,避免长时间高温暴露;存储和贴装应按防潮等级要求执行。
  • 设计时注意结电容对高速信号的影响,必要时在 PCB 布局上采用阻抗匹配与布线优化。

七、结论

LESD5D5.0CT1G-ES 以其低电容、低漏电、双向保护及较高的脉冲能量吸收能力,适合对信号完整性要求高且需 5V 等级保护的各类电子设备。SOD523 尺寸小、易于自动贴装,适配现代紧凑型消费与工业类产品的 ESD 防护需求。若需样片、封装图或更详细的电气特性曲线,可联系 ElecSuper(静芯微)获取完整技术资料。

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
