LM-IP4292CZ10-TBR 产品概述

一、简介

LM-IP4292CZ10-TBR 是 Leiditech(雷卯电子)推出的一款四路单向瞬态抑制器,专为高速差分/单端接口提供过压与浪涌保护。器件采用小外形 DFN2510-10 封装、无铅工艺,能够在不影响信号完整性的前提下对 HDMI、USB、MDDI、千兆以太网等接口提供可靠保护。

二、关键参数

  • 极性:单向
  • 工作电压 Vrwm:5 V(适配标准 5V 电源体系)
  • 击穿电压 VBR:6 V(典型)
  • 钳位电压(Clamping):15 V(最大/典型钳位能力)
  • 反向漏电流 Ir:100 nA(水准为 nA 级)
  • 通道数:四路(可保护 4 条信号线或成对使用)
  • 结电容 Cj:典型 0.3 pF(I/O 对 I/O,超低电容有利于高速信号)
  • 抗浪涌等级:符合 IEC 61000-4-5(雷击/浪涌抗扰能力)

三、主要特性与优势

  • 超低电容(0.3 pF):对差分对或高频串行链路几乎没有负载,确保 HDMI 1.3/1.4/2.0、USB 2.0/3.0 等高速信号链路的信号完整性。
  • 超低泄漏(nA 级):在待机或低功耗场景下对电源与模拟回路影响极小。
  • 低工作电压与低钳位:专为 5 V 系统优化,能在限制电压峰值的同时保护敏感收发器。
  • 四路集成:节省 PCB 面积,简化器件选型与装配。
  • 小型 DFN 封装:适配移动设备、机顶盒与紧凑型主板布局,支持常用回流焊工艺。

四、典型应用场景

  • HDMI 1.3/1.4/2.0 接口保护(TMDS 差分对)
  • USB 2.0 / USB 3.0 上行/下行端口防护
  • MDDI 显示接口及移动多媒体端口
  • 10/100/1000BASE-T 以太网 PHY 前端防护
  • 工业控制与通讯接口的局部浪涌保护

五、PCB 布局与使用建议

  • 将器件尽量靠近接口连接器放置,输入端短距连接以减小未保护段暴露。
  • 暴露焊盘(EP)接地并通过多孔过孔连接到内部地/散热层,以提升浪涌能量分散与热管理。
  • 对差分对保持对称走线,避免在保护器与接收端之间引入不必要的串扰或阻抗突变。
  • 在高频信号路径上避免并联大电容,保持器件的超低寄生电容优势。
  • 推荐遵循器件数据手册中的回流焊温度曲线与焊接工艺说明。

六、封装与订购信息

  • 品牌:Leiditech(雷卯电子)
  • 型号:LM-IP4292CZ10-TBR
  • 封装:DFN2510-10(小型表面贴装,RoHS/无铅兼容)
  • 单芯片四路配置,适合量产与批量装配工艺。

总结:LM-IP4292CZ10-TBR 结合了超低电容、低漏电流与对 5V 系统优化的钳位特性,是对高速接口在空间受限、对信号完整性要求高的应用场合提供保护的理想选择。如需在具体电路中进一步优化布局或评估浪涌能量能力,可提供原理图与 PCB 布局以获取针对性建议。

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
