KESD5Z5.0C 瞬态抑制二极管(ESD防护)产品概述

KESD5Z5.0C是一款双向瞬态抑制二极管(TVS),专为静电放电(ESD)和电快速瞬变脉冲群(EFT)干扰防护设计,具备超小型封装、宽温适应性及高脉冲承受能力,可有效保护后端敏感电子元器件免受瞬态过压损坏。

一、核心参数与电气特性解析

该器件的关键电气参数需结合应用场景重点关注:

  • 极性与截止特性:双向极性设计,可同时防护正、负瞬态脉冲;反向截止电压(Vrwm)为5V,常态下处于截止状态,不影响电路正常工作;击穿电压(Vbr)典型值9V,当脉冲电压超过此值时器件导通,快速泄放能量。
  • 防护能力:峰值脉冲电流(Ipp)达5A,峰值脉冲功率(Ppp)75W,可快速吸收瞬间过压能量;钳位电压(Vc)15V,能将瞬态电压限制在15V以内,匹配多数敏感器件(如MCU、传感器)的安全工作电压范围。
  • 低损耗与高频适应性:反向漏电流(Ir)仅1μA(Vr=5V时),常态漏电流极小,不增加电路额外功耗;结电容(Cj)15pF,对中高速信号传输的干扰较小,适合一般速率的信号线路防护(如USB 2.0、UART等)。

二、封装形式与物理特性

KESD5Z5.0C采用SOD-523封装,属于超小型表面贴装封装,具备以下优势:

  • 尺寸紧凑:封装体积超小,适合高密度PCB设计(如小型化消费电子、物联网节点),可有效节省板级空间;
  • 贴装便捷:符合SMT自动贴装工艺要求,可集成于批量生产流程,提高生产效率,降低人工成本;
  • 引脚兼容:2引脚设计,与同类SOD-523封装器件引脚布局一致,便于后期替换或选型调整。

三、防护性能与国际认证

该器件满足IEC 61000-4-2(ESD) 和 IEC 61000-4-4(EFT) 国际标准,覆盖常见电磁干扰场景:

  • ESD防护:可应对人体接触放电(±8kV典型)、空气放电(±15kV典型)等静电冲击,符合消费电子、工业设备的静电防护等级要求;
  • EFT防护:能抑制电快速瞬变脉冲群干扰(如开关切换、雷电感应产生的脉冲),提升设备的电磁兼容性(EMC),避免误触发或器件损坏。

四、环境适应性与可靠性

KESD5Z5.0C的环境适应性覆盖多数应用场景:

  • 宽温范围:工作结温(Tj)为-40℃~+150℃,可适应低温环境(如北方户外设备)和高温环境(如汽车舱内、工业控制柜),无需额外散热设计;
  • 可靠性:符合行业可靠性标准,长期工作稳定,漏电流无明显漂移,抗老化能力强,适合长期运行的设备(如工业PLC、车载系统)。

五、典型应用场景

该器件因体积小、防护能力强,广泛应用于以下领域:

  1. 消费电子:手机、平板、笔记本的USB、HDMI、耳机接口防护,避免用户接触产生的静电损坏;
  2. 工业控制:PLC、传感器模块的信号输入输出接口防护,应对工业现场的EFT干扰;
  3. 通信设备:路由器、交换机的RJ45接口、射频接口防护,提升设备抗干扰能力;
  4. 汽车电子:车载显示屏、CAN总线接口防护(宽温特性适配汽车环境的温度波动);
  5. 物联网设备:智能穿戴、传感器节点的通信接口防护,满足小型化设计需求。

六、产品优势总结

KESD5Z5.0C的核心优势在于:

  • 双向防护适配正负脉冲,无需额外匹配器件;
  • 超小型SOD-523封装适合高密度板级设计;
  • 宽温范围(-40℃~+150℃)覆盖 harsh环境应用;
  • 低结电容(15pF)兼顾信号传输与防护;
  • 符合IEC 61000-4-2/4-4标准,电磁防护可靠。

该器件是消费电子、工业、通信等领域敏感元器件瞬态防护的高性价比选择,可有效降低设备因瞬态干扰导致的故障率。

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
