SMF13CA瞬态抑制二极管(TVS)产品概述

SMF13CA是扬杰科技(YANGJIE)推出的双向瞬态抑制二极管(TVS),专为低至中压系统的瞬态过压保护设计。凭借紧凑的SOD-123FL封装、宽温工作范围及可靠的脉冲耐受能力,该器件广泛适配消费电子、通信设备及工业控制等领域的接口/电源线路保护需求,是替代传统保护器件的高性价比选择。

一、产品核心定位与典型应用场景

TVS的核心作用是在ns级时间内将线路电压钳位至安全范围,避免后端敏感器件(如IC、传感器)因浪涌/静电放电(ESD)损坏。SMF13CA的双向极性及13V反向截止电压(Vrwm),使其成为以下场景的理想方案:

  1. 消费电子接口保护:手机、平板、笔记本电脑的USB Type-C、HDMI等接口,需同时防护正负脉冲过压(如静电放电±8kV接触放电、电源浪涌);
  2. 通信设备线路防护:路由器、交换机的以太网端口、RS485总线,针对共模/差模浪涌的双向抑制;
  3. 工业控制低功耗模块:PLC、传感器节点的电源/信号线路,适配-55℃~+150℃宽温环境;
  4. 汽车电子辅助电路:车载信息娱乐系统的USB接口、CAN总线(宽温特性可覆盖部分车载低温场景,需结合具体车规认证)。

二、关键电气参数深度解析

SMF13CA的参数设计精准匹配中低压系统的保护需求,核心参数的合理性直接决定其保护可靠性:

(1)极性与截止/击穿特性

  • 双向极性:无需区分正负极,简化PCB设计,同时覆盖正负脉冲过压(如静电放电的双向冲击);
  • 反向截止电压(Vrwm=13V):正常工作时器件反向截止(漏电流仅1μA),不影响系统功耗;仅当线路电压超过Vrwm时,器件进入击穿导通状态;
  • 击穿电压(Vbr=15.9V):反向导通的起始电压,比Vrwm高2.9V,避免系统正常电压波动(如12V电源±10%波动)触发误保护。

(2)钳位与脉冲耐受能力

  • 钳位电压(Vc=21.5V):10/1000μs脉冲峰值时的电压,远低于多数IC的绝对最大额定电压(如25V),可有效抑制浪涌对敏感元件的冲击;
  • 峰值脉冲电流(Ipp=9.3A@10/1000μs):耐受10μs上升、1000μs下降的浪涌电流能力,覆盖常见电源浪涌(如雷击感应、开关浪涌);
  • 峰值脉冲功率(Ppp=200W@10/1000μs):单次脉冲最大耐受功率,经参数验证(Vc×Ipp≈21.5V×9.3A≈200W),一致性可靠。

(3)漏电流与温度特性

  • 反向漏电流(Ir=1μA@Vrwm):正常工作时漏电流极小,对系统静态功耗影响可忽略;
  • 工作温度范围(-55℃~+150℃):符合工业级宽温标准,可在极端环境(沙漠高温、寒带低温)下稳定工作,无需额外散热设计。

三、封装设计与可靠性优势

SMF13CA采用SOD-123FL表面贴装封装,兼顾小型化与可靠性:

  1. 小型化设计:封装尺寸约2.9mm×1.6mm×1.0mm,适配高密度PCB布局(如智能手机主板的紧凑空间);
  2. 无铅环保:采用RoHS compliant无铅封装材料,符合全球电子行业环保要求;
  3. 机械可靠性:引脚镀金工艺抗氧化能力强,引脚间距与PCB焊盘匹配,支持自动化贴装(回流焊/波峰焊兼容);
  4. 热稳定性:封装材料热导率适配150℃工作温度,脉冲工作时无过热失效风险。

四、扬杰科技品牌背书与质量保障

扬杰科技作为国内功率半导体龙头企业,SMF13CA属于其成熟SMF系列TVS产品,质量管控覆盖全流程:

  1. 全流程认证:通过ISO9001、IATF16949(部分产品)认证,关键参数一致性误差≤5%;
  2. 可靠性测试:需通过温度循环(-55℃~+150℃,1000次)、脉冲寿命测试(1000次浪涌冲击)、湿度老化等严苛测试;
  3. 供货稳定性:完善的产能布局可实现批量稳定供货,适配客户量产需求。

总结

SMF13CA双向TVS二极管凭借双向保护、宽温工作、小封装、高脉冲耐受四大核心优势,成为中低压系统过压保护的高性价比选择。其参数精准匹配消费电子、通信、工业等领域实际需求,结合扬杰科技的品牌与质量保障,可有效提升系统抗干扰能力与可靠性。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

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.
