Leiditech ESD5451R-2 静电防护器件产品概述

雷卯电子(Leiditech)推出的ESD5451R-2是一款针对敏感电子电路设计的双向静电放电(ESD)防护二极管,核心作用是泄放瞬态ESD脉冲,避免后端芯片、接口等关键元件因过压损坏。其小封装、低电容、高耐受功率的特性,让它成为消费电子、通信设备等小型化产品的常用防护方案。

一、产品定位与核心价值

ESD5451R-2的设计目标是兼顾“防护可靠性”与“电路兼容性”:

  • 正常工作时保持低阻抗(低漏电流),不干扰信号传输;
  • 遭遇ESD或浪涌脉冲时,快速导通并钳位电压,将脉冲能量泄放到地;
  • 尤其适合低压高速信号路径(如USB、蓝牙、Type-C接口)的防护,避免信号失真。

二、关键性能参数深度解析

要理解该器件的实用性,需结合参数的实际应用意义分析:

1. 工作电压匹配与响应速度

  • 反向截止电压(Vrwm)=5V:正常工作时,反向施加5V以内电压不会导通,精准匹配多数低压电路(如5V供电的USB接口、Type-C端口)的工作范围;
  • 击穿电压(Vbr)=6V:比截止电压略高,脉冲电压超过6V时快速击穿导通——既保证正常工作不干扰,又能实现“毫秒级响应”防护。

2. 防护能力核心指标

  • 钳位电压(Vc)=12.5V:脉冲峰值时将电压钳位在12.5V以内,避免后端芯片IO口(多数耐压阈值10-15V)损坏;
  • 峰值脉冲功率(Ppp)=80W@8/20μs:能承受的最大脉冲能量,“8/20μs”是国际标准浪涌波形(电流波前沿8μs、半峰值时间20μs),可应对人体接触的8kV-15kV ESD及轻度浪涌。

3. 电路兼容性设计

  • 反向电流(Ir)=500nA:纳安级漏电流,正常工作时不消耗额外功率,不影响电路静态性能(如信号电平、电源效率);
  • 结电容(Cj)=15pF:低电容是高速信号防护的关键——电容越低,对高频信号衰减越小,15pF可适配2.4GHz以下高速信号(USB 2.0、蓝牙、HDMI低速率版本)。

4. 国际标准认证

通过IEC 61000-4-2(ESD防护,接触放电8kV/空气放电15kV)和IEC 61000-4-5(浪涌防护)测试,符合全球EMC要求,无需额外验证即可用于出口产品。

三、封装与可靠性设计

ESD5451R-2采用DFN1006封装:

  • 尺寸仅1.0mm×0.6mm×0.4mm(超小型),适合智能手机、智能手表、蓝牙耳机等紧凑设备;
  • 无引脚设计,焊接可靠性高,抗机械应力能力强,适配批量自动化生产;
  • 工作温度范围-55℃至125℃,满足工业级及消费级设备的环境要求。

四、典型应用场景

该器件的特性决定了它适用于以下场景:

  1. 消费电子接口:智能手机USB Type-C、耳机孔,平板电脑充电接口,防护插拔静电;
  2. 通信设备端口:路由器以太网口、无线AP天线接口,防护雷电感应及静电;
  3. 便携设备:蓝牙耳机、智能手环信号链路,匹配小封装需求;
  4. 工业控制:PLC输入输出端口,符合IEC标准,满足工业级防护要求。

五、品牌与技术优势

雷卯电子作为国内专注过压防护的厂商,ESD5451R-2的优势在于:

  • 精准适配市场:5V工作电压、15pF低电容,针对主流低压高速电路;
  • 高性价比:相比进口同类器件,性能相当但价格更具竞争力;
  • 本地化服务:提供技术支持与样品快速交付,适合国内中小厂商研发生产。

总结来说,ESD5451R-2是一款“小而强”的ESD防护器件,兼顾防护性能、电路兼容性与封装小型化,是消费电子、通信等领域的实用选择。

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
