晶导微电子SMF14CA TVS二极管产品概述

SMF14CA是晶导微电子推出的一款双向瞬态抑制二极管(TVS),专为电路瞬态过压防护设计,采用小型表面贴装封装SOD-123FL,具备宽温工作、高脉冲承受能力等特点,适用于多种电子设备的过压保护场景。

一、产品基本信息

SMF14CA属于TVS二极管范畴,核心功能是快速抑制电路中的瞬态过压脉冲,保护后端敏感元器件免受浪涌损坏。其基础信息如下:

  • 品牌:晶导微电子
  • 类型:双向TVS二极管(无需区分正负极,安装灵活)
  • 封装:SOD-123FL(小型表面贴装封装,适配高密度PCB布局)
  • 反向截止电压(Vrwm):14V(最大反向工作电压,正常工作时不击穿)

二、核心电性能参数

SMF14CA的关键电参数决定了其过压保护能力,具体如下:

  1. 钳位电压(Vc):23.2V(电路出现瞬态过压时,TVS快速导通,将电压钳位在23.2V左右,有效限制后端电压);
  2. 峰值脉冲电流(Ipp):8.6A(10/1000μs波形下的最大脉冲电流承受能力,该波形为行业标准浪涌测试波形,模拟实际场景);
  3. 峰值脉冲功率(Ppp):200W(10/1000μs波形下的最大脉冲功率,反映TVS抗过压冲击强度);
  4. 击穿电压(Vbr):17.2V(典型击穿电压,高于反向截止电压,确保正常工作时不导通);
  5. 反向漏电流(Ir):1μA(反向截止电压14V下的漏电流,数值极低,不影响电路正常功耗);
  6. 工作温度范围:-55℃~+150℃(宽温设计,可适应工业级、高温环境需求)。

三、封装与应用优势

SMF14CA采用SOD-123FL封装,具备以下实用优势:

  • 小型化:封装体积小(常见尺寸约2.9×1.6×1.1mm),适合智能手机、可穿戴设备等小型电子设备的高密度PCB设计;
  • 双向保护:无需区分正负极,简化电路设计与安装流程,降低出错概率;
  • 自动化兼容:支持表面贴装自动化生产,提高生产效率,降低制造成本。

四、典型应用场景

SMF14CA的宽温特性与高脉冲承受能力,使其适用于多种场景:

  1. 消费电子:手机、平板、蓝牙耳机等设备的USB接口、充电端口过压保护;
  2. 工业控制:PLC模块、传感器节点、工业通信接口的瞬态过压防护;
  3. 通信设备:路由器、交换机、光模块的信号端口浪涌保护;
  4. 小型家电:智能插座、遥控器、小型智能设备的电源/信号过压防护;
  5. 工业级设备:需适应极端温度的工业传感器、数据采集模块等。

五、关键特性总结

SMF14CA的核心特性可概括为:

  • 宽温可靠:-55℃~+150℃,覆盖工业级环境需求;
  • 抗冲击强:200W峰值脉冲功率,应对常见浪涌冲击;
  • 低功耗:1μA反向漏电流,不影响电路正常工作;
  • 安装灵活:双向设计+小型封装,适配多种电路布局;
  • 保护精准:明确钳位电压(23.2V),快速抑制过压保护后端器件。

这款TVS二极管通过平衡体积、功率承受能力与温度范围,成为小型电子设备过压防护的实用选择,可满足多数消费电子、工业控制场景的过压保护需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
