5.0SMDJ26CA-AT/13瞬态抑制二极管(TVS)产品概述

5.0SMDJ26CA-AT/13是台湾君耀(Brightking)推出的一款双向瞬态抑制二极管(TVS),采用SMC(DO-214AB)表面贴装封装,专为电子设备的瞬态过压防护设计,核心适配12V/24V系统,可有效应对静电放电(ESD)、雷击浪涌及脉冲干扰,兼顾小体积与高防护能力。

一、产品核心定位与应用场景

该产品属于SMDJ系列TVS,聚焦中低电压系统的高可靠性瞬态防护,主要面向以下领域:

  1. 通信设备:路由器、交换机的RJ45接口、USB接口防护;
  2. 工业控制:PLC模块、传感器节点的输入输出端口防护;
  3. 汽车电子:车载传感器(温度/压力传感器)、中控单元的过压防护;
  4. 消费电子:智能家电主板、显示器接口的静电/浪涌防护。

其双向极性设计无需区分电路正负,可直接适配交流或直流系统,简化了电路设计流程。

二、关键电气参数与性能优势

产品参数围绕“低功耗、高防护能力”优化,核心指标及实际价值如下:

  • 反向截止电压(Vrwm):26V
    精准适配12V/24V直流系统(24V系统正常工作电压通常≤26V),正常工作时不导通,不影响电路原有功能。
  • 钳位电压:42.1V
    脉冲干扰时,能快速将电压钳位在42.1V以下,远低于后级敏感元件(如MCU、芯片)的最大耐压(通常3.3V/5V系统耐压≤60V),有效避免元件损坏。
  • 峰值脉冲电流(Ipp):119A
    配合峰值脉冲功率(Ppp):5kW@10/1000μs(行业标准浪涌波形),可承受强瞬态冲击(如雷击、电机启停干扰),防护能力远超常规TVS。
  • 反向漏电流(Ir):2μA
    反向截止时漏电流极小,不增加系统静态功耗,适合低功耗设备(如电池供电的传感器)。
  • 击穿电压:28.9V
    击穿电压稳定在Vrwm(26V)之上,确保正常工作时不误击穿,脉冲触发时快速导通防护。

三、封装与可靠性设计

  1. SMC(DO-214AB)封装
    表面贴装形式,体积小巧(尺寸约5.8×3.8×2.0mm),适合高密度PCB布局(如手机、汽车电子模块);封装采用耐高温材料,焊接可靠性高。
  2. 宽温工作范围:-55℃~+150℃
    覆盖工业级及汽车级温度要求,可在极端环境(沙漠高温、寒带低温)下稳定工作,无需额外散热设计。
  3. 品牌可靠性
    君耀(Brightking)作为专业TVS制造商,产品通过温度循环、焊接冲击等严格可靠性测试,批次一致性好,降低系统故障风险。

四、符合标准与防护等级

该产品满足IEC 61000-4-2静电放电防护标准,可应对接触放电(±8kV/±15kV)及空气放电(±15kV/±25kV)场景,符合电子设备的ESD防护要求;同时兼容IEC 61000-4-5浪涌防护标准(部分测试),可同时应对静电与浪涌干扰。

五、典型应用案例参考

以工业PLC输入端口防护为例:
PLC输入端口连接12V供电传感器,易受现场浪涌(电机启停干扰)及静电冲击。5.0SMDJ26CA-AT/13并联在端口与地之间,正常工作时(输入电压≤26V)漏电流仅2μA,不影响传感器信号;当浪涌电压升至40V以上时,快速导通将电压钳位在42.1V以下,保护PLC输入芯片不受损坏,提升系统稳定性。

总结:5.0SMDJ26CA-AT/13凭借双向防护、高脉冲能力、宽温范围及小体积优势,成为12V/24V系统瞬态防护的高性价比选择,适用于多领域电子设备的可靠性设计需求。

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
