LM-SE05NRE14GA 产品概述

一、产品简介

LM-SE05NRE14GA 是 Leiditech(雷卯电子)推出的一款四通道低电容 ESD 防护二极管阵列,专为高速数据接口和精密信号线提供静电放电与雷击浪涌保护而设计。器件工作电压低至 5V,具有极低结电容和超低泄漏电流,适用于对信号完整性要求高的 HDMI、USB、MDDI 及千兆以太网等接口保护场景。

二、核心性能

  • 反向工作电压 Vrwm:5V
  • 击穿电压 VBR:6V(典型)
  • 钳位电压(对浪涌/ESD):典型 15V
  • 反向漏电流 Ir:100nA(典型,低泄漏)
  • 通道数:四路(最多保护 4 条线路)
  • 结电容 Cj:典型 0.3pF(I/O 对 I/O,超低电容)
  • 防护等级:符合 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)要求
  • 封装:DFN2510-10,环保无铅封装
  • 类型:ESD/浪涌保护阵列

三、主要特性

  • 超低电容(典型 0.3pF):最大程度降低对高速差分信号(如 HDMI、USB3.0)信号完整性的影响。
  • 超低泄漏(nA 级):适合对偏置与模拟测量要求高的线路,避免影响电路静态性能。
  • 低工作电压与低钳位:为低压信号系统提供有效保护同时减小对受保护器件的应力。
  • 四路集成:一颗器件即可保护多条信号线,节省 PCB 面积与物料成本。
  • 符合国际电磁兼容标准:通过 IEC 61000-4-2 与 IEC 61000-4-5 等测试要求,适配工业与消费类应用。

四、典型应用

  • HDMI 1.3 / 1.4 / 2.0 接口保护(TMDS 差分对)
  • USB 2.0 / USB 3.0 数据线与接口防护
  • MDDI 与其他高速移动界面
  • 10/100/1000Base-T(千兆以太网)PHY 端口保护
  • 摄像头模块、显示模组与移动设备 I/O 保护

五、应用建议与注意事项

  • 布局:将器件尽量靠近受保护的连接器入线处布置,短接地回流路径以保证 ESD 能量快速泄放。
  • 接地:保证 GND 区域低阻抗、短回路,必要时配合隔离地平面与过孔优化回流。
  • 差分对:0.3pF 的超低电容有利于差分对保持阻抗匹配,但仍需注意器件寄生与走线一致性。
  • 环境与焊接:DFN2510-10 为无铅环保封装,遵循对应的回流焊工艺规范以避免器件应力。

六、选用理由与优势

LM-SE05NRE14GA 将超低电容、超低漏电与高防护等级在单颗四通道器件中结合,特别适合对高速差分信号与低压器件保护要求较高的应用场景。相比于普通 TVS 器件,其对信号完整性的影响更小、集成度更高,有利于简化 PCB 布局并提高可靠性。

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
