LRC8804FDT1G ESD防护二极管产品概述

一、产品定位

LRC8804FDT1G是乐山无线电(LRC)针对高速电子设备接口静电防护需求推出的四路集成ESD二极管,采用DFN2510超小型无引脚封装,兼具低电容、高防护能力与多通道集成特性,可有效抑制静电放电(ESD)对敏感电路的瞬时过压损害,适用于消费电子、移动终端、工业通信等多领域的信号接口防护。

二、核心电气参数解析

产品参数围绕“防护能力”“信号兼容性”“集成特性”三类核心需求设计,关键参数如下:

1. 防护性能参数

  • 反向截止电压(Vrwm):5V
    设备正常工作时,二极管反向偏置电压不超过5V即处于截止状态,不干扰信号传输;
  • 击穿电压(Vbr):5.5V
    当静电脉冲使电压超过5.5V时,二极管快速导通,释放静电能量,避免后端电路过压损坏;
  • 峰值脉冲电流(Ipp):5A
    可承受强静电脉冲冲击,满足高频次、高强度ESD防护需求;
  • 钳位电压(Vc):10V
    当通过5A脉冲电流时,二极管两端电压被钳位在10V以内,有效保护敏感器件。

2. 信号兼容性参数

  • 结电容(Cj):0.3pF(标称范围0.25pF~0.3pF)
    低电容特性可降低对高速信号的串扰与损耗,支持1GHz以上高频信号(如USB3.0、HDMI2.0)传输;
  • 反向漏电流(Ir):300nA
    正常工作电压下漏电流极小,对系统静态功耗影响可忽略。

3. 集成特性

内置四路独立防护通道,可同时对多路信号线路(如数据、电源、时钟)进行ESD防护,减少元件数量与PCB布线复杂度。

三、封装与制造工艺

采用DFN2510无引脚封装,尺寸为2.5mm×1.0mm×0.6mm,具备以下优势:

  • 无引脚设计降低寄生电感/电阻,进一步提升信号完整性;
  • 超小体积适合高密度PCB布局,满足便携设备小型化需求;
  • 兼容SMT自动化贴装工艺,生产效率高。

制造工艺遵循LRC成熟半导体流程,封装材料符合环保要求,可在-55℃~125℃宽温范围内稳定工作。

四、典型应用场景

  1. 移动终端:智能手机、平板的USB Type-C、HDMI、音频接口防护;
  2. 消费电子:智能电视、机顶盒的HDMI、USB、以太网接口;
  3. 工业设备:传感器模块、PLC通信接口、工业以太网端口;
  4. 通信设备:路由器、交换机的高速数据接口(如SFP、RJ45)。

五、关键优势特点

  1. 高速信号兼容:0.3pF低结电容避免高速信号失真,适合1GHz以上高频传输;
  2. 高ESD防护等级:符合IEC 61000-4-2标准,可承受接触放电8kV、空气放电15kV;
  3. 多通道集成:四路通道减少元件数量,优化PCB空间利用;
  4. 低功耗设计:300nA漏电流不增加系统静态功耗;
  5. 宽温可靠性:-55℃~125℃工作温度范围,满足工业级应用需求。

六、符合标准与环保要求

除IEC 61000-4-2静电放电标准外,产品还符合RoHS 2.0(无铅)、REACH等环保法规,可用于全球市场的电子设备设计。

LRC8804FDT1G通过平衡“防护能力”与“信号完整性”,成为高速接口ESD防护的高性价比选择,适用于对体积、功耗、性能有严格要求的电子设备。

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
