Brightking SMCJ70A/TR13 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心属性

SMCJ70A/TR13是台湾君耀(Brightking)推出的单向贴片瞬态抑制二极管(TVS),属于SMCJ系列的主力防护型号。作为电路过压保护的核心器件,其设计针对70V等级电路的浪涌/静电防护需求,兼具低漏电流、高脉冲耐受能力,适配表面贴装工艺,广泛覆盖通信、工业、消费电子等领域。

二、关键电气参数深度解析

SMCJ70A/TR13的参数围绕“防护有效性”与“电路兼容性”优化,核心参数解析如下:

1. 电压防护核心指标

  • 反向截止电压(Vrwm):70V:正常工作时可承受的最大反向直流电压,需与电路工作电压匹配(如电源电压≤70V时直接并联防护);
  • 击穿电压(Vbr):77.8V:反向电压超过此值时,器件快速击穿进入导通状态(典型值确保批量一致性);
  • 钳位电压(Vclamp):113V:峰值脉冲下的最大电压阈值,需低于被保护IC的最大耐压(如IC耐压≥120V时安全)。

2. 脉冲耐受能力

  • 峰值脉冲功率(Ppp):1.5kW:单次脉冲可承受的最大功率(对应1.2/50μs或8/20μs标准浪涌波形);
  • 峰值脉冲电流(Ipp):13.3A:由Ppp=Vclamp×Ipp推导(113V×13.3A≈1500W),反映抗浪涌电流的能力。

3. 低功耗与可靠性参数

  • 反向漏电流(Ir):1μA(Vrwm下):正常工作时漏电流极低,不增加电路待机功耗,适合对功耗敏感的设备(如便携式电子)。

三、封装与可靠性设计

SMCJ70A/TR13采用SMC(DO-214AB)标准贴片封装,具备以下优势:

  1. 体积紧凑:典型尺寸为6.1mm×5.0mm×2.3mm,适配高密度PCB设计,节省布局空间;
  2. 贴装友好:引脚间距符合自动化贴装标准,兼容回流焊/波峰焊工艺,生产效率高;
  3. 散热可靠:封装结构优化热传导路径,快速散除脉冲热量,避免过热失效;
  4. 环保合规:符合RoHS、REACH标准,无铅无卤,适配全球市场。

四、品牌与质量保障

Brightking(君耀)是专注保护器件的台系厂商,拥有20余年研发经验,其TVS器件特点:

  • 批量一致性好,避免参数离散导致防护失效;
  • 产品通过工业级可靠性测试(温度循环、湿热老化),部分型号符合AEC-Q101汽车级标准;
  • 全球服务网络覆盖,提供技术支持与样品验证。

五、典型应用场景

SMCJ70A/TR13参数匹配性使其适用于:

  1. 通信设备:基站RRU电源、路由器/交换机接口,应对雷击浪涌与静电放电;
  2. 工业控制:PLC、传感器模块电源,抑制开关浪涌与感应过压;
  3. 消费电子:显示器HDMI/VGA接口、机顶盒电源,保护显示芯片与主控IC;
  4. 车载电子(若为汽车级):车载充电器、CAN总线接口,应对汽车环境过压冲击。

六、选型注意事项

  1. 极性匹配:单向TVS需反向并联于被保护端口,避免接反失效;
  2. 电压裕量:Vrwm需高于电路最大工作电压(如电路60V,70V裕量充足);
  3. 后级耐压:钳位电压113V需低于被保护器件的最大耐压。

该器件凭借平衡的防护能力与封装优势,成为70V等级电路过压保护的高性价比选择。

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
