LESD8LS5.0CT5G ESD防护器件产品概述

乐山无线电(LRC)推出的LESD8LS5.0CT5G是一款专为低电压电路设计的双向ESD防护器件,针对静电放电(ESD)干扰提供可靠防护,同时兼顾高频信号传输性能,符合国际通用的IEC 61000-4-2防护标准,广泛适配消费电子、工业控制等领域的5V供电系统。

一、产品核心定位与品牌依托

LESD8LS5.0CT5G属于LRC旗下成熟的ESD防护产品线,依托LRC在半导体元器件领域的研发与制造积累,该器件聚焦低电压系统的静电防护,同时优化了高频性能,解决了传统ESD器件“防护能力与信号完整性矛盾”的痛点,适合对信号传输质量要求较高的场景。

二、关键电气性能参数详解

该器件的核心参数针对5V系统做了精准匹配,以下是关键性能的详细说明:

1. 极性与反向截止电压

  • 极性:双向:可同时防护电路的正、负向静电脉冲,无需区分正负极,简化电路设计与安装流程,降低布线复杂度。
  • 反向截止电压(Vrwm):5V:正常工作状态下,器件反向不导通的最大电压,完美适配5V供电的电子系统(如多数消费电子、低电压工业模块),不会因器件导通干扰系统正常运行。

2. 击穿电压与反向漏电流

  • 击穿电压:6V:当静电脉冲电压超过6V时,器件快速击穿导通,将脉冲能量泄放至地,实现防护功能,响应速度快(典型ns级)。
  • 反向漏电流(Ir):1μA:极低的漏电流,确保在正常工作电压下,器件不会消耗额外功率,也不会对敏感电路的信号传输造成干扰(如MCU、传感器的模拟信号)。

3. 钳位电压与峰值脉冲电流

  • 钳位电压:18.4V:器件击穿后,可将电路上的电压钳位在18.4V以内,有效保护后端敏感元器件免受高压损坏(如避免IC击穿、电容击穿)。
  • 峰值脉冲电流(Ipp):2.5A:可承受最大2.5A的ESD脉冲电流,满足IEC 61000-4-2标准中对静电放电的防护要求(接触放电8kV、空气放电15kV),应对日常使用中的静电冲击(如人体接触、设备插拔)。

4. 结电容与高频性能

  • 结电容(Cj):0.4pF:低结电容设计是该器件的核心优势之一,可减少对高频信号的衰减与失真,适合高速接口(如USB 2.0/3.0、HDMI、LVDS)的静电防护,保证信号完整性(如避免视频信号花屏、数据传输丢包)。

三、封装与可靠性设计

  • 封装:SOD-882:采用超小型贴片封装,尺寸紧凑(典型尺寸约1.6mm×0.8mm×0.5mm),适合高密度PCB布局,尤其适合便携电子设备(如手机、智能手表)的小型化设计需求,安装便捷且兼容性强(可兼容自动贴片机)。
  • 防护标准:IEC 61000-4-2:符合国际电工委员会(IEC)的静电放电防护标准,可靠性经测试验证,可长期稳定工作(工作温度范围通常为-55℃~150℃,满足工业与消费电子的环境要求)。

四、典型应用场景

结合该器件的性能特点,主要应用于以下场景:

  1. 消费电子领域:手机、平板、笔记本电脑的USB接口、HDMI端口、音频接口等高速信号接口的静电防护;智能穿戴设备(如智能手表、手环)的按键与信号线路防护。
  2. 工业控制领域:低电压(5V)工业传感器、PLC模块的输入输出接口防护,避免静电干扰导致的设备误触发或损坏(如传感器数据异常、PLC停机)。
  3. 通信设备领域:路由器、交换机的以太网接口、光纤收发器的信号接口防护,保证数据传输稳定(如避免因静电导致的网络卡顿)。

LESD8LS5.0CT5G通过精准的参数优化与可靠的防护设计,平衡了静电防护性能与信号完整性,是5V系统中高速接口与敏感电路静电防护的理想选择。

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
