1.5KE16CA 瞬态抑制二极管(TVS)产品概述

1.5KE16CA是RUILON(瑞隆源)推出的一款双向瞬态抑制二极管(TVS),采用DO-201AD轴向封装,专为电路中的瞬态过压防护设计,具备宽温适应、高脉冲耐受能力,可有效抑制雷电、静电放电(ESD)、开关浪涌等瞬态干扰,保护后端敏感电子元件。

一、产品基本属性

作为1.5kW级TVS器件,1.5KE16CA属于单路通道设计,核心特性包括:

  • 极性:双向导通,可同时防护正、负向瞬态过压;
  • 封装:DO-201AD轴向插件封装,引脚间距符合标准,适配通用PCB插件工艺;
  • 工作温度:-55℃至+150℃宽温范围,满足工业级、汽车级等恶劣环境需求;
  • 品牌:RUILON(瑞隆源),国内知名半导体器件厂商,产品可靠性经行业验证。

二、核心电气参数解析

1.5KE16CA的关键参数直接决定其防护性能,各参数实际意义如下:

1. 反向截止电压(Vrwm=13.6V)

指器件在正常工作状态下可承受的最大反向直流电压,此时器件处于截止状态,漏电流极小。选型时需确保该参数高于系统正常工作电压(如12V系统适配此型号),避免器件误导通。

2. 击穿电压(Vbr=16.8V)

是器件反向开始导通的电压阈值,比Vrwm高约2.4V(典型TVS击穿电压与截止电压的偏差范围),当系统电压超过此值时,器件快速击穿,将过压能量泄放。

3. 钳位电压(Vc=23.5V)

指器件在承受峰值脉冲电流时,两端的最大电压(即后端电路可被保护的最高电压)。该参数需远低于后端敏感元件(如IC、电容)的最大承受电压,1.5KE16CA的23.5V钳位电压可有效保护多数12V系统的后端器件。

4. 峰值脉冲电流(Ipp=67A@10/1000μs)

“10/1000μs”是脉冲波形标准(上升时间10μs,半峰值时间1000μs,模拟雷电或开关浪涌波形),67A是器件在此波形下可承受的最大单次脉冲电流,反映其浪涌耐受能力。

5. 峰值脉冲功率(Ppp=1.5kW@10/1000μs)

是上述脉冲波形下的最大功率值,1.5kW的功率容量可覆盖多数中功率电路的浪涌防护需求(如工业电源、汽车电子总线)。

6. 反向漏电流(Ir=1μA)

指Vrwm电压下的反向漏电流,仅1μA说明器件截止状态漏电极小,不会影响系统正常工作电流。

三、封装与可靠性设计

1.5KE16CA采用DO-201AD轴向封装,具备以下优势:

  • 散热性能:轴向封装的引脚与封装体接触面积大,配合PCB焊盘可有效散发热量,避免多次浪涌后器件过热损坏;
  • 机械强度:封装结构坚固,可承受振动、冲击等环境应力,适合汽车、工业现场等振动场景;
  • 宽温可靠性:-55℃至+150℃的工作温度范围,覆盖了绝大多数工业设备(如户外PLC、车载控制器)的环境温度需求,无需额外温控措施。

四、典型应用场景

1.5KE16CA因双向防护、高功率耐受等特性,广泛应用于以下领域:

  1. 工业控制电路:PLC输入输出接口、传感器信号端、电机驱动电路的过压防护;
  2. 汽车电子系统:车载12V电源总线、CAN/LIN总线、车灯控制电路的浪涌抑制;
  3. 通信设备:基站电源端口、路由器/交换机的电源及信号接口防护;
  4. 消费电子:电源适配器、显示器、机顶盒的过压保护(防止雷击或电网浪涌损坏);
  5. 新能源领域:光伏逆变器、储能系统的辅助电源防护。

五、选型与使用注意事项

  1. 选型匹配:

    • Vrwm需高于系统正常工作电压(如12V系统选13.6V合适,避免误触发);
    • 钳位电压需低于后端元件的最大承受电压(如IC耐压25V则此型号适配);
    • 脉冲功率需覆盖系统可能出现的最大浪涌功率(1.5kW可满足多数中功率场景)。
  2. 安装要点:

    • 双向器件无极性,但轴向封装需注意引脚与PCB的焊接方向(避免反向安装不影响性能,但需符合设计规范);
    • 焊盘面积需足够(建议≥10mm²),以增强散热;
    • 尽量靠近被保护元件,减少引线电感(避免浪涌电压在引线上的压降)。
  3. 可靠性维护:

    • 避免超过最大脉冲电流/功率使用,否则可能导致器件永久损坏;
    • 长期工作时需确保环境温度不超过+150℃,避免结温过高。

1.5KE16CA凭借双向防护、高功率耐受、宽温可靠等特性,成为工业、汽车、通信等领域中12V系统过压防护的主流选型之一,可有效提升电路的抗干扰能力与可靠性。
