SMF24CA 瞬态抑制二极管(TVS)产品概述

SMF24CA是富芯森美(FUXINSEMI)推出的一款双向瞬态抑制二极管(TVS),专为电子电路的过压防护设计,可有效抑制静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌等瞬态干扰,保护敏感元器件免受损坏。该器件具备宽温适应性、高脉冲耐受能力与紧凑封装,适用于消费电子、工业控制、汽车电子等多领域场景。

一、核心参数概览

SMF24CA的核心参数针对电路防护需求优化,关键指标如下:

  • 极性:双向设计,无需区分正负极,简化电路布局;
  • 电压类参数:反向截止电压(Vrwm)24V(正常工作时不导通的最高电压),击穿电压26.7V(接近截止电压,响应更精准),钳位电压38.9V(脉冲干扰时将电压钳位至该值以下,保护后级电路);
  • 脉冲耐受能力:峰值脉冲电流(Ipp)5.4A,峰值脉冲功率(Ppp)200W(测试波形为10/1000μs,符合行业标准脉冲测试要求);
  • 低功耗特性:反向电流(Ir)仅5μA,正常工作时漏电流极小,不影响电路正常功耗;
  • 通道数:单路设计,适配单点防护需求;
  • 温度范围:工作温度-55℃~+150℃,覆盖工业级与汽车级严苛环境。

二、关键性能特点

  1. 双向防护无极性:双向极性设计使器件无需考虑电路正负极,安装灵活,尤其适合接口电路等无固定极性的防护场景;
  2. 精准钳位与低漏电流:击穿电压(26.7V)与反向截止电压(24V)接近,响应速度快;钳位电压稳定在38.9V,可有效限制后级电路的过压幅度;反向电流仅5μA,低漏电流特性避免了正常工作时的功耗损耗;
  3. 高脉冲耐受能力:200W峰值脉冲功率(10/1000μs波形)与5.4A峰值电流,可应对常见的强瞬态干扰(如雷击感应、电源浪涌),防护可靠性高;
  4. 宽温工作适应性:-55℃至+150℃的工作温度范围,满足工业现场(如户外传感器)、汽车电子(如发动机舱周边)等高低温环境的使用需求;
  5. 符合国际防护标准:通过IEC 61000-4-2防护等级认证,兼容静电放电(ESD)等常见干扰测试,符合电子设备的电磁兼容(EMC)要求。

三、封装与可靠性

SMF24CA采用SOD-123FL小型表面贴装封装,具有以下优势:

  • 紧凑尺寸:封装尺寸小巧(典型值约2.9mm×1.6mm×1.0mm),适合高密度PCB设计(如智能手机、可穿戴设备);
  • 焊接兼容性:兼容回流焊、波峰焊等标准表面贴装工艺,生产效率高;
  • 可靠性高:封装材料耐温性能与器件工作温度范围匹配,长期使用无性能衰减,符合工业级可靠性要求。

四、典型应用场景

SMF24CA的性能特点使其适用于多领域的过压防护:

  1. 消费电子:智能手机、平板电脑、可穿戴设备的USB接口、音频接口、充电端口防护,抑制静电与浪涌;
  2. 工业控制:PLC模块、工业传感器、现场总线接口的瞬态干扰防护,适应工业现场的高低温与电磁环境;
  3. 汽车电子:车载娱乐系统、胎压监测传感器、车身控制模块的接口防护,满足汽车级温度与可靠性要求;
  4. 通信设备:路由器、交换机、基站的以太网接口、射频接口防护,抑制电磁干扰与浪涌;
  5. 电源电路:低电压直流电源(如5V、12V)端口的浪涌防护,避免电源过压损坏负载。

五、品牌与合规性

富芯森美(FUXINSEMI)是国内专业的半导体器件厂商,专注于过压防护器件的研发与生产,SMF24CA具备以下合规性:

  • 符合IEC 61000-4-2(ESD防护)、IEC 61000-4-4(EFT防护)等国际电磁兼容标准;
  • 生产过程遵循ISO 9001质量管理体系,器件一致性与可靠性有保障;
  • 无铅封装,符合RoHS环保要求,适配全球市场需求。

SMF24CA凭借双向防护、宽温适应性、高脉冲耐受能力与紧凑封装,成为各类电子设备过压防护的可靠选择,可有效提升电路的抗干扰能力与使用寿命。

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
