SMF16CA 瞬态抑制二极管(TVS)产品概述

一、产品基本定位与核心类型

SMF16CA是固得沃克(GOODWORK) 推出的一款双向瞬态抑制二极管(TVS),属于过压保护类核心器件,主要用于吸收电路中的瞬态脉冲干扰(如静电放电、电源浪涌、雷击感应等),避免后端敏感电子元件(如IC、传感器、接口芯片)因过压损坏。该型号针对低电压电路设计,参数匹配常见12V/16V系统的保护需求,封装紧凑,适用于高密度PCB布局场景。

二、关键电气参数解析

SMF16CA的电气参数经过优化,满足低电压过压保护的核心需求,关键参数及意义如下:

  1. 反向截止电压(Vrwm):16V
    此为TVS正常工作时可承受的最大反向直流电压,当电路电压稳定在16V及以下时,器件处于截止状态,漏电流极小,不影响电路正常运行;若电压超过16V但未达击穿电压,器件仍保持高阻态,确保电路稳定性。
  2. 钳位电压:26V(@峰值脉冲电流)
    钳位电压是TVS导通后将电压限制在的最大峰值,对应8/20μs标准脉冲波形下的7.7A峰值脉冲电流(Ipp),可有效将瞬态过压限制在后端元件的耐压范围内(通常IC耐压多在20-30V左右)。
  3. 峰值脉冲功率(Ppp):200W
    最大瞬态功率承受能力,即器件可吸收的瞬时能量上限,能应对常见的浪涌干扰(如电源启动时的尖峰、静电放电的瞬时能量)。
  4. 反向击穿电压:17.8V
    反向偏置下器件开始导通的临界电压,比Vrwm高1.8V,确保正常电压下不导通,过压时快速响应(响应时间达ns级)。
  5. 反向漏电流(Ir):1uA
    反向截止状态下的漏电流,仅为微安级,远低于多数同类产品,说明器件截止特性优异,不会导致电路功耗增加或信号干扰。

三、封装与物理特性

SMF16CA采用SOD-123FL 表面贴装封装,具有以下优势:

  • 尺寸紧凑:典型尺寸约2.0mm×1.25mm×1.0mm,适合高密度PCB设计(如手机、小型控制器);
  • 贴片安装:无引脚设计(或低引脚),便于自动化贴装,生产效率高;
  • 散热性佳:封装结构利于热量扩散,结合150℃的结温上限,可稳定承受瞬态功率冲击。

四、典型应用场景

SMF16CA的参数与封装特性,使其适用于以下场景:

  1. 消费电子:手机、平板、智能穿戴的充电接口(USB Type-C)、数据接口(HDMI、耳机孔)的过压保护;
  2. 汽车电子:车载小功率传感器(如温度、压力传感器)、CAN总线接口、低电压控制电路的浪涌保护(支持-55℃~+150℃宽温);
  3. 工业控制:PLC(可编程逻辑控制器)的输入输出接口、低电压传感器模块的ESD/浪涌防护;
  4. 通信设备:路由器、交换机的以太网接口、电源模块的瞬态干扰抑制。

五、可靠性与环境适应性

SMF16CA具备优异的可靠性,可适应严苛环境:

  • 宽温范围:工作结温(Tj)覆盖-55℃~+150℃,满足汽车级、工业级应用的温度要求;
  • 双向保护:无需区分正负极,简化电路设计,降低安装错误风险;
  • 抗干扰能力:200W峰值脉冲功率可有效抑制静电放电(ESD)、电源浪涌(如1.2/50μs脉冲)等干扰,保护后端元件。

六、品牌与选型价值

固得沃克作为国内半导体器件主流厂商,SMF16CA具有以下选型优势:

  • 质量稳定:经过严格的可靠性测试(如温度循环、老化测试),性能一致性好;
  • 性价比高:替代进口同类产品(如对应部分进口SMF16CA型号),成本更低;
  • 技术支持完善:提供选型指导、应用方案设计等服务,适合中小批量到大规模生产需求。

综上,SMF16CA是一款性能均衡、封装紧凑的双向TVS二极管,可广泛应用于消费电子、汽车电子、工业控制等领域的低电压过压保护场景,是替代进口产品的优质选择。

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.
