SMDJ24A/TR13 TVS二极管产品概述

一、产品核心定位与基本属性

SMDJ24A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),属于表面贴装型过压防护器件,核心作用是抑制电子电路中的瞬态过电压冲击,保护敏感元器件免受雷击、静电放电(ESD)、电源浪涌等异常电压损坏。该器件采用SMC(DO-214AB)封装,体积紧凑、贴装便捷,适配高密度电路设计需求,是消费电子、工业控制、通信设备等领域的通用防护方案。

二、关键电气参数解析

1. 反向工作与击穿特性

  • 反向截止电压(Vrwm=24V):电路正常工作时,反向偏置下不导通的最大电压,确保器件在额定电压下无漏电流干扰,避免影响电路效率;
  • 击穿电压(Vbr=26.7V):器件开始导通的电压阈值,比Vrwm高约11%,避免因电压波动误触发防护功能;
  • 反向漏电流(Ir=2μA):低漏电流设计可减少正常工作时的功率损耗,提升电路长期稳定性。

2. 瞬态冲击防护能力

  • 峰值脉冲电流(Ipp=77.1A):可承受高强度瞬态浪涌(如雷击瞬间电流);
  • 峰值脉冲功率(Ppp=3kW):能快速耗散大能量脉冲,避免器件过热损坏;
  • 钳位电压(Vc=38.9V):脉冲冲击时器件两端的峰值电压,远低于电子元件常规损坏阈值(多在50V以下),有效保护后端敏感器件。

3. 宽温工作适应性

工作温度覆盖**-55℃~+150℃**,满足工业级、汽车电子等 harsh 环境的温度要求,极端低温(如户外冬季)或高温(如设备满负荷运行)下仍能稳定防护,无需额外温度补偿。

三、封装与工艺可靠性

SMDJ24A/TR13采用SMC(DO-214AB)表面贴装封装,尺寸约3.2mm×2.7mm×1.1mm,体积小、重量轻,适配自动化贴装生产线,可大幅提升电路集成度。封装具备以下优势:

  • 无铅环保:符合RoHS指令要求,适配绿色制造需求;
  • 焊接可靠:支持回流焊、波峰焊等常规工艺,长期使用不易脱焊、开裂;
  • 热传导优化:封装设计缩短热路径,快速散发脉冲能量,避免器件过热失效。

四、典型应用场景

1. 消费电子接口防护

适用于手机、平板、笔记本的USB、HDMI、Type-C接口,小体积可嵌入紧凑设备内部,抑制人体接触时的静电放电(ESD)和接口浪涌。

2. 工业控制与传感器

工业PLC、温度/压力传感器的信号端口防护,宽温特性适配车间、户外等复杂环境,高脉冲功率抵御工业现场电磁干扰浪涌。

3. 通信设备端口

路由器、交换机、基站的以太网端口、射频接口防护,77.1A峰值脉冲电流可应对雷击浪涌,保障通信设备稳定运行。

4. 汽车电子低压系统

车载信息娱乐系统、辅助驾驶传感器的12V/24V电路防护,宽温范围覆盖汽车级温度要求(-40℃~+125℃),补充适配极端低温场景。

五、品牌与品质保障

台湾君耀(Brightking)是全球知名的过压保护器件制造商,SMDJ系列是其经典表面贴装TVS产品线,产品通过ISO 9001、IATF 16949等认证,符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等国际标准。SMDJ24A/TR13采用高可靠性芯片设计,批次一致性好,已广泛应用于国内外电子厂商量产产品,品质稳定可靠。

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
