SMDJ26CAQ 瞬态抑制二极管(TVS)产品概述

SMDJ26CAQ是扬杰科技(YANGJIE)推出的双向瞬态抑制二极管(TVS),专为电子电路的过压保护设计,可快速抑制瞬态浪涌电压对敏感元器件的损坏,适配工业控制、汽车电子、通信设备等多场景应用,具备宽温、高抗浪涌等核心优势。

一、产品核心定位与类型

TVS(瞬态抑制二极管)是电子系统的关键防护器件,其工作原理为:当反向电压超过击穿阈值时,迅速从高阻态转为低阻态,将浪涌电压钳位在安全范围,避免后端电路因过压损坏。SMDJ26CAQ作为双向TVS,无需区分正负极即可实现对正负瞬态脉冲的同步抑制,设计兼容性更强,安装更便捷。

二、关键电气参数解析

SMDJ26CAQ的参数经过优化,精准匹配低电压系统的防护需求,核心参数如下:

  • 极性:双向(正负脉冲均能有效抑制);
  • 反向截止电压(Vrwm):26V(电路正常工作时,TVS可承受的最大反向电压,无导通漏电流);
  • 击穿电压(Vbr):31.9V(反向电压达到此值时,TVS启动击穿导通,进入保护状态);
  • 钳位电压(Vc):42.1V(10/1000μs标准浪涌波形下,TVS可将电压钳位至的最大值,确保后端电路安全);
  • 峰值脉冲电流(Ipp):71.26A@10/1000μs(对应波形下,TVS可耐受的最大峰值脉冲电流);
  • 峰值脉冲功率(Ppp):3kW@10/1000μs(同波形下的最大脉冲功率耐受能力,体现抗浪涌强度);
  • 反向漏电流(Ir):1μA(反向截止状态下的漏电流极小,不影响电路静态功耗);
  • 工作温度范围:-55℃~+175℃(宽温设计,适配极端环境应用)。

三、封装与品牌优势

  • 封装形式:DO-214AB(SMC封装),表面贴装式设计,体积小巧(尺寸约6.0×5.0×2.3mm),可节省PCB空间,适合高密度电路布局;同时SMC封装具备良好的散热性能,能快速 dissipate 脉冲能量,避免器件过热损坏;
  • 品牌背景:扬杰科技是国内半导体器件领域的龙头企业,TVS产品线覆盖全系列规格,产品经过严格的可靠性测试(如温度循环、浪涌寿命测试、ESD测试等),质量稳定可靠,可满足工业级、汽车级等严苛应用要求。

四、典型应用场景

SMDJ26CAQ的参数特性使其适配多类低电压电子系统的浪涌防护,典型应用包括:

  1. 工业控制电路:24V直流电源系统、PLC输入输出端口,防护电源开关浪涌、感应雷击;
  2. 汽车电子:车载24V电源系统、传感器接口(温度/压力传感器),适配汽车级温度范围(-40℃~+125℃),甚至覆盖极端工况;
  3. 通信设备:路由器、交换机、光模块的电源端口,抑制静电放电(ESD)、线路浪涌;
  4. 消费电子:充电器、智能家居设备的电源电路,防护市电波动、静电干扰;
  5. 电源模块:DC-DC转换器、开关电源输出端,防止负载突变或外部浪涌损坏。

五、产品核心优势总结

  1. 双向保护简化设计:无需区分正负极,降低安装与电路设计复杂度,减少误装风险;
  2. 宽温适配极端环境:-55℃~+175℃的工作温度范围,可覆盖工业高温、户外低温等场景;
  3. 强抗浪涌能力:3kW峰值功率、71A峰值电流,可有效抑制强瞬态浪涌(如雷击、大电流开关浪涌);
  4. 低功耗不影响系统:1μA反向漏电流,对电路静态功耗影响可忽略;
  5. 小型化适配高密度:SMC封装体积小,适合便携式设备、小型模块的紧凑布局;
  6. 可靠品牌保障:扬杰科技的成熟工艺与可靠性测试,确保批量应用的稳定性。

综上,SMDJ26CAQ是一款高性价比的双向TVS管,适合低电压电子系统的瞬态过压防护,可满足工业、汽车、通信等多领域的应用需求。

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
