Brightking SMDJ30A/TR13 TVS二极管产品概述

一、产品定位与核心功能

SMDJ30A/TR13是台湾君耀(Brightking)推出的单向瞬态抑制二极管(TVS),专为电子电路中的瞬态过压防护设计,可快速抑制静电放电(ESD)、雷电浪涌、电源开关瞬态等脉冲干扰,避免后端敏感元器件(如IC、传感器、微处理器)因过压损坏,提升电路长期可靠性。作为贴片式保护器件,其紧凑封装适配高密度PCB布局,适用于多场景电子设备。

二、核心电性能参数详解

该型号TVS的关键参数围绕“快速响应、高效钳位”设计,核心指标及意义如下:

  1. 反向截止电压(Vrwm):30V
    常态工作下可长期承受的最大反向电压,确保电路正常运行时器件不导通,无额外功耗损耗。
  2. 击穿电压(Vbr):33.3V(典型值)
    反向击穿的起始电压,保证过压事件发生时快速导通(响应时间ns级),及时分流脉冲能量。
  3. 钳位电压(Vc):48.4V(@峰值脉冲电流Ipp=62A)
    峰值脉冲下的最大电压,是保护后端器件的核心指标——该值越低,对敏感元件的保护效果越强。
  4. 峰值脉冲电流(Ipp):62A(8/20μs波形)
    可承受的最大瞬态脉冲电流,满足多数中等功率浪涌场景(如电源端口、通信接口)的防护需求。
  5. 峰值脉冲功率(Ppp):3kW
    与Ipp、Vc对应,反映器件的瞬态功率耐受能力,覆盖常见浪涌能量范围。
  6. 反向漏电流(Ir):2μA(@Vrwm)
    常态下漏电流极小,避免器件自身功耗对电路信号/电源的干扰。
  7. 工作温度范围:-55℃~+150℃
    宽温特性适配工业、汽车等** harsh 环境**(如车载高温、户外低温)。

三、封装形式与物理特性

采用SMC(DO-214AB)贴片封装,符合国际标准:

  • 尺寸紧凑(典型尺寸:约6.0mm×5.0mm×2.3mm),适配高密度PCB设计,支持自动化贴装(SMT),提升生产效率;
  • 封装可靠性高,焊接牢固,抗机械应力能力强,适合长期在振动、冲击环境下使用;
  • 单向极性,安装时需注意极性方向(通常印字端为负极),确保防护有效性。

四、品牌与可靠性保障

台湾君耀(Brightking)是全球知名的保护器件制造商,专注于TVS、压敏电阻等防护元件研发生产20余年,产品符合RoHS、REACH等环保标准,部分型号通过AEC-Q101汽车级认证(该型号宽温特性适配汽车电子需求)。
SMDJ30A/TR13的低漏电流、宽温范围及高脉冲耐受能力,经批量可靠性测试验证,可确保在长期使用中性能稳定,降低电路故障风险。

五、典型应用场景

该型号TVS广泛应用于以下领域:

  1. 消费电子:手机、平板、笔记本电脑的USB接口、HDMI端口、音频接口防护,抑制ESD及静电浪涌;
  2. 工业控制:PLC、工业传感器、伺服驱动器的电源端口及信号线路防护,应对工业现场的电磁干扰;
  3. 汽车电子:车载音响、车载摄像头、胎压监测系统(TPMS)的电路防护,适配-40℃~+85℃(部分场景更高)的汽车工作环境;
  4. 通信设备:路由器、交换机、基站的以太网端口、射频接口防护,抵御雷电浪涌及静电干扰。

总结

SMDJ30A/TR13平衡了小封装、宽温、高脉冲耐受能力,是多场景电子电路过压防护的实用选择,尤其适合对体积、温度、可靠性有要求的工业、汽车及消费电子领域。

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
