Brightking SMBJ150CA/TR13 瞬态抑制二极管(TVS)产品概述

SMBJ150CA/TR13是台湾君耀(Brightking)推出的双向表面贴装瞬态抑制二极管(TVS),采用SMB(DO-214AA)封装,专为电路瞬态过压保护设计,尤其适配工业控制、电源模块、通信接口等对可靠性和环境适应性要求较高的场景。

一、产品基本定位与核心功能

作为典型TVS器件,SMBJ150CA/TR13的核心作用是快速响应电路瞬态过压,将电压钳位在安全范围,保护后端敏感元件(如MCU、ADC、通信芯片)免受浪涌损坏。其双向极性设计无需区分电路正负极,可直接并联于被保护端口,简化设计流程,同时适配AC电源输入、差分通信总线等无极性电路的保护需求。

二、关键电气参数解析

SMBJ150CA/TR13的参数经过严格标定,核心指标结合应用场景解读如下:

1. 电压类参数

  • 反向截止电压(Vrwm):150V
    正常工作时TVS反向截止,允许电路电压最高达150V而不导通,确保电路无干扰运行。
  • 击穿电压(Vbr):185V
    当电压超过185V时,TVS反向击穿并快速导通,启动保护机制;君耀对该参数一致性管控严格,批量产品偏差极小。
  • 钳位电压(Vc):243V
    峰值脉冲电流(2.5A@10/1000us)下,TVS两端电压被钳位在243V,远低于多数敏感元件的耐受极限(如工业MCU电源端耐压通常≤200V,此钳位值可有效防护)。

2. 电流与功率参数

  • 峰值脉冲电流(Ipp):2.5A@10/1000us
    10/1000us为浪涌波形(上升10μs、半峰值1000μs),TVS可承受最大2.5A峰值电流,满足IEC61000-4-5标准中2kV/1.2/50us浪涌(假设浪涌阻抗2Ω,峰值电流≈1A,远低于2.5A)。
  • 峰值脉冲功率(Ppp):600W@10/1000us
    浪涌功率P=Vc×Ipp≈243V×2.5A=607W,与标称值一致,是判断TVS浪涌能力的核心指标。
  • 反向漏电流(Ir):1μA
    正常工作时(Vrwm下)漏电流仅1μA,几乎不消耗电路功率,不影响后端元件性能。

3. 温度参数

  • 工作温度:-65℃~+150℃
    覆盖工业级温度标准,可适应北方户外低温、工业控制柜内高温等极端环境,可靠性突出。

三、封装与可靠性特性

1. SMB(DO-214AA)封装

SMB为表面贴装结构,体积小巧(典型尺寸2.3mm×1.6mm×1.0mm),适配高密度PCB设计(如小型电源模块、便携式设备);封装采用耐高温环氧树脂,符合RoHS无铅环保要求,兼容现代制造工艺。

2. 品牌可靠性

君耀作为专业保护器件厂商,SMBJ150CA/TR13经过温度循环、湿度老化、机械振动等严格测试,产品一致性好,可稳定应用于批量生产。

四、典型应用与设计要点

1. 典型应用场景

  • 工业控制:PLC数字/模拟量端口、传感器接口,抑制电机启停、静电放电等浪涌;
  • 电源系统:AC/DC输入端(双向保护AC浪涌)、DC-DC输出端,保护后端负载;
  • 通信接口:RS485、CAN总线、以太网端口,抑制差分信号瞬态过压;
  • 汽车电子:12V/24V车载电源、传感器接口(部分宽温汽车应用)。

2. 设计注意事项

  • 并联安装:TVS需直接并联于被保护元件两端,靠近端口减少引线电感(电感会降低保护效果);
  • 功率余量:实际浪涌功率建议不超过标称值的80%(480W),避免长期脉冲导致器件疲劳;
  • 配合保险丝:TVS防护过压,若出现过流(如击穿短路),需保险丝熔断防止电路损坏;
  • 电压范围:确认电路正常电压≤150V,避免TVS误导通。

五、产品优势总结

  1. 双向保护简化设计:无极性要求,适配无极性电路,降低设计复杂度;
  2. 宽温适应性:-65℃~+150℃满足工业级要求,覆盖极端环境;
  3. 高浪涌承受力:600W峰值功率、2.5A峰值电流,应对主流浪涌标准;
  4. 小体积高密度:SMB封装节省PCB空间,适配小型化设备;
  5. 低漏电流无干扰:1μA漏电流不影响电路正常工作,功耗极低。

SMBJ150CA/TR13凭借稳定性能、宽温适应性和小体积设计,成为工业控制、电源、通信等领域瞬态过压保护的可靠选择。
