Leiditech ESD9D5C 双向ESD防护器件产品概述

一、产品定位与核心价值

Leiditech(雷卯电子)ESD9D5C是一款专为低电压(≤5V)电路设计的双向ESD防护器件,核心作用是在电路遭受静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌冲击时,快速钳位过电压至安全范围,保护后级敏感元件(如MCU、传感器、通信芯片等)免受损坏。其核心优势在于高防护能力与低结电容的平衡——既满足严苛的电磁兼容标准,又不影响信号传输质量,适配小型化、低功耗电子设备的设计需求。

二、关键电气参数解析

ESD9D5C的参数针对低电压防护场景优化,核心指标清晰指向防护与信号兼容性:

  • 反向截止电压(Vrwm):5V:正常工作时器件反向偏置不导通,漏电流极小,不干扰电路运行;
  • 最小击穿电压(Vbr(min)):6V:电压超过5V并达6V时,器件启动导通防护,避免过压累积;
  • 钳位电压(Vc):11.6V:峰值脉冲下将过电压钳位至11.6V以内,确保后级元件安全;
  • 峰值脉冲电流(Ipp):5A@10/1000μs:可承受5A浪涌脉冲(10/1000μs波形),应对中等强度浪涌;
  • 峰值脉冲功率(Ppp):150W@8/20μs:8/20μs标准浪涌波形下峰值功率达150W,防护可靠性高;
  • 结电容(Cj):15pF:低结电容设计,对USB 2.0、UART等低速数字信号传输无明显失真影响。

三、多标准电磁防护能力

该器件符合IEC 61000-4系列国际电磁兼容标准,覆盖主流干扰场景:

  • IEC 61000-4-2(ESD):可承受人体接触放电(8kV)、空气放电(15kV),应对日常静电干扰(如人体触摸设备);
  • IEC 61000-4-4(EFT):抑制±2kV典型幅值的电快速瞬变脉冲群,避免敏感芯片误触发;
  • IEC 61000-4-5(浪涌):承受±2kV/±1kA(线对地/线对线)浪涌冲击,防护电源/信号线上的瞬态过压。

四、电气特性与可靠性

  • 双向防护结构:内置双向钳位电路,正、反向过压均快速响应,无需额外配置单向器件,简化电路布局;
  • 低反向漏电流:Vrwm=5V时反向漏电流(Ir)仅1μA,远低于同类器件,保证电路低功耗;
  • SOD-923封装优势:体积小巧(约1.6×0.8×0.6mm),适配智能手机、可穿戴等小型化设备;表面贴装工艺兼容性好,长期工作稳定性高。

五、典型应用场景

ESD9D5C适用于低电压电子设备的接口及信号线路防护,典型场景包括:

  1. 消费电子:手机、平板、笔记本的USB接口、HDMI接口、耳机孔、充电端口;
  2. 可穿戴设备:智能手表、手环的充电接口、心率/加速度传感器信号线路;
  3. 通信设备:路由器、交换机的以太网端口、Wi-Fi天线接口;
  4. 工业控制:低电压PLC的数字I/O端口、传感器接口;
  5. 车载电子:车载中控屏USB接口、低电压信息娱乐系统信号线路(需结合车载温度验证)。

六、总结

Leiditech ESD9D5C是一款高性价比双向ESD防护器件,以5V截止电压适配低电压电路,通过多标准防护、低结电容及小体积封装,满足消费电子、通信、可穿戴等领域的静电与浪涌防护需求,是敏感元件防护的可靠选择。

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
