Brightking SMBJ110CA/TR13 瞬态抑制二极管(TVS)产品概述

SMBJ110CA/TR13是台湾君耀(Brightking)推出的双向贴片瞬态抑制二极管(TVS),采用SMB(DO-214AA)封装,专为电子设备的瞬态过压防护设计,可有效抑制静电放电(ESD)、雷电感应浪涌及电路开关瞬态干扰,保障敏感元器件(如MCU、传感器、通信芯片)的正常工作。产品兼顾小体积、高防护能力与宽温适应性,是工业、通信、消费电子等领域的高性价比防护方案。

一、产品核心定位与典型应用场景

SMBJ110CA/TR13的核心定位是中低压电路的双向瞬态过压防护器件,无需区分正负极,适配交流/直流双向浪涌场景,典型应用包括:

  1. 电源输入端口:110V直流/交流系统(如小型工业电源、车载辅助电源)的过压防护;
  2. 工业通信接口:RS485、CAN总线、Modbus等工业现场总线的浪涌抑制;
  3. 敏感模块防护:PLC输入输出模块、传感器节点、低功耗MCU的ESD与浪涌防护;
  4. 消费电子与车载:小型电源适配器、车载中控屏、倒车雷达等设备的瞬态干扰防护。

二、关键电气性能参数详解

产品参数围绕“瞬态防护能力”与“正常工作稳定性”设计,核心参数及意义如下:

  1. 极性:双向设计
    无需区分正负极,简化电路设计与焊接工艺,适配交流/直流双向浪涌(如电源正负极反接、通信线双向干扰)。

  2. 反向截止电压(Vrwm):110V
    正常工作状态下(无浪涌),器件可承受的最大反向电压,此时处于截止状态,漏电流极小,不影响电路正常运行。

  3. 击穿电压(Vbr):122V(典型值)
    器件开始导通的电压阈值——当浪涌电压超过122V时,TVS迅速从截止态转为低阻态,将电压钳位在安全范围。

  4. 钳位电压(Vc):177V(@Ipp=3.4A)
    浪涌峰值电流下器件两端的最大电压,是保护后端电路的核心指标(需确保Vc低于被保护元器件的耐压极限)。

  5. 峰值脉冲电流(Ipp):3.4A
    器件可承受的单次峰值浪涌电流(μs级),超过该值可能导致器件失效,需与电路浪涌能量匹配。

  6. 峰值脉冲功率(Ppp):600W
    浪涌时的最大功率耗散,反映器件防护能力上限(Ppp = Vc × Ipp,体现单次浪涌的能量耐受)。

  7. 反向漏电流(Ir):1μA(@Vrwm)
    正常工作时漏电流极小,对电路功耗影响可忽略,提升系统能效与长期稳定性。

  8. 工作温度范围:-65℃+150℃
    宽温设计,满足工业级(-40℃+85℃)、车载级(-40℃~+125℃)等恶劣环境需求,支持极端温度下的持续工作。

三、封装与可靠性设计

  1. SMB封装特点
    采用DO-214AA贴片封装,体积仅约2.5×5.0×1.0mm,适合高密度PCB布局;支持回流焊工艺(260℃/10s),生产效率高,适配自动化组装线。

  2. 可靠性保障

    • 君耀成熟的半导体工艺,确保参数一致性(批量生产偏差小);
    • 低漏电流设计,长期工作无明显功耗累积,避免器件过热;
    • 符合RoHS环保标准,无铅无卤,适配绿色电子产品设计。

四、选型与应用注意事项

  1. 选型匹配原则

    • Vrwm需略高于电路最大正常工作电压(如110V电路优先选110V Vrwm的TVS);
    • 浪涌能量需与Ppp、Ipp匹配(可通过浪涌测试仪验证,避免超过额定值)。
  2. 应用设计要点

    • 直接并联在被保护电路两端(无需串接电阻,若需限流需注意压降);
    • 布局尽可能靠近被保护端口(减少引线电感,提升防护响应速度);
    • 焊接时控制回流焊温度,避免超过封装耐受极限(SMB封装建议260℃/10s以内)。
  3. 常见误区规避

    • 不可用于持续过压防护(仅适用于μs级瞬态浪涌,持续过压会导致器件烧毁);
    • 双向TVS无需极性判断,避免因正负极接反而失效。

总结

SMBJ110CA/TR13凭借双向防护、小体积、宽温范围及可靠的电气性能,成为中低压电路过压防护的高性价比选择。其适配多领域应用场景,有效提升电子设备的抗干扰能力与可靠性,是工业、通信、消费电子等行业的成熟防护方案。
