SMBJ180CA/TR13 TVS二极管产品概述

SMBJ180CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),专为电子电路的过压防护设计,采用SMB(DO-214AA)贴片封装,兼顾小体积与可靠防护能力,广泛适配工业、通信、消费电子等领域的过压保护需求。

一、产品基本定位与核心标识

该型号的命名包含明确的技术与封装信息,便于工程选型:

  • SMB:对应DO-214AA贴片封装,体积紧凑(典型尺寸约3.5mm×2.5mm×1.5mm),适合自动化表面贴装,适配空间受限的PCB设计;
  • J:代表君耀TVS二极管系列,属于该品牌成熟的防护器件产品线;
  • 180:核心反向截止电压(Vrwm)指标,即电路正常工作时TVS保持高阻态的最大反向电压;
  • CA:标识双向极性,可同时防护正、负瞬态过压,无需区分焊接正负极;
  • TR13:通常为编带包装标识,支持批量生产中的自动化贴装,提升生产效率。

二、关键电性能参数深度解析

SMBJ180CA/TR13的电性能参数针对典型过压场景优化,核心指标的意义需结合实际应用理解:

  1. 极性与防护方向:双向设计是该型号的核心优势之一,可同时抑制电路中的正脉冲浪涌(如电源尖峰)与负脉冲干扰(如静电放电反向脉冲),简化电路布局;
  2. 反向截止电压(Vrwm):180V,确保在电路正常工作电压范围内(如工业110V/220V系统的降压后电路、120V电源模块)保持高阻态,不影响电路正常功能;
  3. 击穿电压(Vbr):201V(典型值),当电路电压超过此阈值时,TVS快速由高阻态转为低阻态,响应时间仅为纳秒级,迅速泄放浪涌电流;
  4. 钳位电压(Vc):292V(峰值脉冲下),是浪涌过程中后级敏感元件(如IC、传感器)可承受的最高电压,该指标直接决定防护有效性(若钳位电压过高,可能损坏负载;过低则易误触发);
  5. 峰值脉冲功率(Ppp)与电流(Ipp):600W/2.1A(8/20μs标准脉冲波形下),可耐受常见的雷电感应浪涌、开关浪涌及静电放电(ESD)能量;
  6. 反向漏电流(Ir):1μA(Vrwm下),低漏电流特性避免了正常工作时的额外功耗,提升电路效率,尤其适合低功耗设备。

三、封装与可靠性保障

SMB(DO-214AA)封装与君耀的工艺保障了产品的可靠性:

  • 封装优势:贴片式设计便于自动化生产,焊盘面积可有效传导脉冲热量,避免局部过热损坏;无引脚设计减少了寄生电感,提升瞬态响应速度;
  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无卤,适配绿色电子产品的市场需求;
  • 可靠性测试:君耀针对该型号完成了多项严苛测试:① 脉冲寿命测试(1000次8/20μs脉冲后性能无衰减);② 高温老化(125℃/1000h);③ 湿度循环(85℃/85%RH),确保长期稳定工作;
  • 质量认证:部分批次通过AEC-Q101(汽车电子标准),可适配部分低压汽车辅助电路(需确认具体批次)。

四、典型应用场景

SMBJ180CA/TR13的参数适配多类电子设备的过压防护需求:

  1. 工业控制领域:PLC输入输出接口、传感器(温度、压力、流量传感器)信号端,防护现场浪涌干扰(如电机启停、雷电感应);
  2. 通信设备:路由器、交换机、光模块的电源端口与以太网接口,抑制雷电感应浪涌(典型10/350μs波形);
  3. 消费电子:机顶盒、智能显示器、智能家居设备的电源适配器输出端,防护开关浪涌(如电源通断时的电压尖峰);
  4. 电源系统:小型开关电源、电池充电电路的过压保护,避免电压异常损坏电池或负载(如120V电池组充电电路);
  5. 医疗设备:部分低压医疗仪器(如监护仪传感器接口)的瞬态防护,符合低干扰、高可靠性要求。

五、产品竞争优势总结

相较于同类TVS器件,SMBJ180CA/TR13具备以下核心优势:

  • 双向防护简化设计:无需正负极区分,降低电路布局复杂度,减少焊接错误;
  • 参数匹配性强:180V截止电压适配中高压电路,292V钳位电压与180V截止电压的差值合理(约60%),既保证防护有效性,又避免误触发;
  • 高性价比:君耀成熟工艺降低了成本,SMB封装适合批量应用,是中高压防护的高性价比选择;
  • 低功耗特性:1μA漏电流不影响电路正常工作效率,适合低功耗设备(如物联网终端)。

该型号是中高压电子电路过压防护的可靠选择,可有效提升设备的抗干扰能力与使用寿命,广泛应用于工业、通信、消费电子等领域。

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.
