晶导微电子SMF60CA TVS二极管产品概述

SMF60CA是晶导微电子针对敏感电子电路浪涌防护需求开发的双向瞬态抑制二极管(TVS),采用SOD-123FL小型表面贴装封装,兼具高脉冲功率容量、宽温度适应性与双向防护特性,可有效抑制静电放电(ESD)、雷电浪涌及瞬态过压对后级电路的冲击,广泛适配工业控制、通信设备、消费电子等多领域应用场景。

一、产品基本信息

类别 详情 品牌 晶导微电子(国内半导体行业知名厂商) 产品类型 双向TVS二极管(瞬态抑制二极管) 封装形式 SOD-123FL(小型表面贴装封装) 核心功能 双向过压保护,抑制正负瞬态浪涌冲击

SOD-123FL封装尺寸紧凑(典型尺寸约2.4mm×1.6mm×1.0mm),适合高密度PCB布局;双向导通特性无需区分正负极,简化电路设计与焊接工艺,提升生产效率。

二、核心电气参数详解

SMF60CA的关键参数围绕“浪涌防护能力”与“正常工作可靠性”设计,核心参数及意义如下:

1. 反向截止电压(V₍rwm₎):60V

表示正常工作状态下,器件可承受的最大反向直流电压(或峰值交流电压),当电路电压未超过60V时,TVS处于截止状态,仅存在极小漏电流,不影响电路正常运行。

2. 击穿电压(V₍br₎):73.7V

当电路电压超过此值时,TVS进入雪崩击穿状态,迅速导通并分流浪涌电流,是“从截止到保护”的临界电压,其值略高于V₍rwm₎可避免误触发。

3. 钳位电压(V₍c₎):96.8V

击穿后,TVS可将浪涌电压钳位在该值,是保护后级电路的核心参数——后级敏感元件(如MCU、传感器)的最大耐受电压需高于96.8V,确保浪涌被有效抑制。

4. 峰值脉冲电流(I₍pp₎):1.8A@10/1000μs

10/1000μs为国际标准浪涌波形(前沿10μs升至峰值,半峰值持续1000μs),表示该波形下TVS可承受的最大峰值浪涌电流,反映器件的电流耐受能力。

5. 峰值脉冲功率(P₍pp₎):200W@10/1000μs

对应同一浪涌波形的最大脉冲功率,直接体现TVS的浪涌能量吸收能力,200W功率在SOD-123FL封装中属于高功率密度设计。

6. 反向漏电流(I₍r₎):1μA

正常工作时(V≤V₍rwm₎)的反向漏电流,仅1μA的低漏电流可避免器件自身功耗对电路的影响,尤其适合低功耗应用场景。

7. 工作温度范围:-55℃~+150℃

覆盖工业级温度标准(-40℃+85℃)及部分汽车级需求(-55℃+125℃),可稳定工作于高低温极端环境,如户外通信设备、工业烤箱等场景。

三、封装与可靠性特性

SOD-123FL封装具备以下优势:

  • 小型化:适合便携式设备(如智能手机)、高密度PCB(如服务器主板)的空间受限场景;
  • 热稳定性:封装材料耐温性好,配合150℃最高工作温度,可快速 dissipate 脉冲能量;
  • 机械可靠性:表面贴装工艺兼容性强,可通过回流焊、波峰焊等批量生产工艺,抗机械应力能力满足工业级振动要求;
  • 抗静电能力:内置ESD防护特性,可承受人体模型(HBM)15kV以上静电冲击(晶导微电子典型参数)。

四、典型应用场景

SMF60CA的双向防护、宽温及高功率特性,使其适配多类场景:

  1. 通信设备:路由器、交换机的以太网接口(POE供电端)、光纤收发器的信号端口,防护雷电浪涌与静电;
  2. 工业控制:PLC输入输出接口、4-20mA传感器(如温度/压力传感器)、伺服电机驱动电路,应对工业现场的电磁干扰(EMI)浪涌;
  3. 消费电子:智能手机Type-C充电接口、平板音频接口、蓝牙耳机充电盒,防护静电放电与过压;
  4. 汽车电子:车载显示屏信号接口、胎压监测传感器(TPMS)、倒车雷达,满足车载环境的宽温与浪涌要求;
  5. 电源电路:低压直流电源(12V/24V)的输出端,防护负载短路或反向过压导致的浪涌。

五、产品选型优势

相较于同封装、同电压等级的TVS器件,SMF60CA具备以下核心优势:

  • 双向防护无需极性区分:简化电路设计,避免焊接错误,提升生产良率;
  • 高功率密度:200W峰值功率在SOD-123FL封装中表现突出,空间利用率高;
  • 宽温覆盖工业/汽车级:-55℃~+150℃远超普通消费级器件,适配极端环境;
  • 低漏电流低功耗:1μA漏电流不影响低功耗电路(如IoT设备)的待机功耗;
  • 国产可靠供应:晶导微电子具备成熟的封装与测试能力,产品一致性好,供货稳定,可替代进口同类器件。

总结

SMF60CA作为一款高性价比的双向TVS二极管,通过紧凑封装、宽温特性与双向防护能力,有效解决了敏感电路的浪涌防护问题。其在工业控制、通信、消费电子等领域的广泛适用性,使其成为工程师设计过压保护电路的理想选择,可显著提升电路的抗干扰性与可靠性,降低浪涌导致的设备损坏风险。
