Brightking SMCJ5.0CA/TR13 TVS二极管产品概述

一、产品基本信息

SMCJ5.0CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),专为电路系统中的浪涌电压防护设计。该器件采用SMC(DO-214AB)表面贴装封装,体积紧凑(参考尺寸:长4.7mm×宽2.6mm×高1.6mm),适配高密度PCB布局,广泛应用于消费电子、工业控制、通信等领域的过压保护场景。

二、核心电气参数解析

该器件的关键参数直接决定其浪涌防护能力,具体解析如下:

  1. 反向截止电压(Vrwm):5V
    指器件正常工作时(无浪涌)可承受的最大反向电压,此时器件处于截止态,漏电流极小,不影响电路正常运行。
  2. 钳位电压:9.2V
    浪涌到来时,器件将后级电路电压钳位到的安全值——当浪涌电压超过击穿电压后,器件快速导通,避免敏感元件(如IC、传感器)因过压损坏。
  3. 峰值脉冲电流(Ipp):163A@10/1000μs
    其中“10/1000μs”为浪涌脉冲波形(上升时间10μs,半峰值时间1000μs),表示器件可承受的最大脉冲电流强度,能有效应对雷击、开关浪涌等强干扰。
  4. 峰值脉冲功率(Ppp):1.5kW@10/1000μs
    对应上述脉冲波形下的最大承受功率,是衡量器件浪涌防护能力的核心指标之一。
  5. 击穿电压:7V
    器件反向导通的起始电压——浪涌电压达到7V时,器件从截止态快速切换为导通态,开始抑制过压。
  6. 反向漏电流(Ir):800μA
    反向截止状态下的漏电流,数值较低,确保正常工作时功耗小,不影响原电路效率。

三、典型应用场景

该器件适配多领域的浪涌防护需求,典型场景包括:

  • 消费电子:手机、平板、笔记本的USB接口、充电端口防护;
  • 工业控制:PLC输入输出模块、传感器节点的过压保护(应对现场开关浪涌);
  • 通信设备:路由器、交换机、基站的以太网端口、射频接口防护(抵御雷击浪涌);
  • 汽车电子(部分场景):车载USB、温度传感器接口防护(适配宽温范围)。

四、关键性能优势

  1. 双向保护:无需区分正负极,简化电路设计与安装流程,适合双向信号线路防护;
  2. 快速响应:TVS二极管响应时间达ns级,可瞬间抑制浪涌,保护敏感元件;
  3. 宽温可靠性:工作温度范围为-65℃~+150℃,覆盖户外、工业高温/低温环境;
  4. 低功耗:800μA漏电流,正常工作时几乎不额外消耗功率;
  5. 高性价比:君耀成熟品牌,性能与成本平衡,适合批量应用。

五、使用注意事项

  1. 选型匹配:仅适用于5V系统的双向过压保护,若系统电压偏离需更换对应型号;
  2. 布局优化:尽量靠近被保护端口(如USB接口),减少引线长度以降低电感干扰;
  3. 焊接参数:回流焊温度≤260℃(持续≤10s),波峰焊温度≤245℃(持续≤5s);
  4. 静电防护:焊接前佩戴静电手环,避免器件因ESD损坏;
  5. 额定限制:严禁超过Vrwm、Ipp等额定参数使用,以免器件失效。

该器件凭借稳定的浪涌防护能力、紧凑封装及宽温适应性,成为5V系统过压保护的主流选型之一。

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
