SEMTECH SM24.TCT 瞬态抑制二极管(TVS)产品概述

SM24.TCT是SEMTECH公司推出的一款双向瞬态抑制二极管(TVS),专为电子电路中的静电放电(ESD)、电快速瞬变脉冲群(EFT)及浪涌等瞬态过压干扰设计,具备宽温度范围、低漏电流、小体积集成等核心优势,可有效保护敏感元器件免受瞬态冲击损坏,适用于工业、消费电子、物联网等多领域场景。

一、核心防护性能参数

SM24.TCT的防护参数针对常见瞬态干扰进行优化,关键指标及应用意义如下:

  • 双向极性:可同时应对正负方向的瞬态过压,无需额外匹配方向,简化电路设计;
  • 反向截止电压(Vrwm):24V:正常工作时(低于此电压)处于截止状态,不影响电路信号传输,适配24V供电系统;
  • 钳位电压:43V:过压时快速将电压钳位至43V以内,保护后端MCU、传感器等敏感元器件不被击穿;
  • 峰值脉冲电流(Ipp):5A@8/20μs:可承受8/20μs波形的5A浪涌电流,满足IEC 61000-4-5浪涌防护要求;
  • 峰值脉冲功率(Ppp):300W:单次浪涌功率容量为300W,可应对典型工业/消费电子场景的瞬态冲击;
  • 击穿电压:26.7V:过压触发阈值明确,确保在Vrwm(24V)以上时快速导通防护,避免误触发。

二、电气特性与环境适应性

除防护参数外,SM24.TCT的静态电气及环境指标适配多场景需求:

  • 反向漏电流(Ir):1μA:反向截止时漏电流极低,不会消耗额外功率,也不影响低功耗电路(如物联网模块)的正常工作;
  • 结电容(Cj):60pF/50pF:结电容处于低至中等水平,既满足高频信号链路(如USB、HDMI)的传输要求,也能兼顾普通数字电路的防护;
  • 工作温度范围:-55℃~+125℃(结温Tj):覆盖工业级温度区间,可在极端低温(户外工业设备)或高温(车载电子)环境下稳定工作;
  • 双路通道设计:封装内集成双路TVS管,可同时防护两路信号或电源线路,进一步节省PCB空间。

三、封装与可靠性设计

SM24.TCT采用SOT-23-3封装,具有以下实用特点:

  • 小体积集成:封装尺寸紧凑(典型值1.6mm×1.2mm×0.8mm),适合便携电子、物联网模块等小型化设备;
  • 高可靠性:封装工艺成熟,可承受机械应力及环境变化,配合宽温设计,长期工作稳定性高;
  • 易焊接性:兼容标准贴片工艺,便于自动化生产,降低焊接成本,适合批量应用。

四、典型应用场景

结合SM24.TCT的参数特性,其典型应用包括:

  1. 工业控制电路:PLC输入输出接口、传感器节点、电机驱动电路等,需应对工业环境中的浪涌及EFT干扰;
  2. 消费电子接口:手机、平板、笔记本的USB Type-C、HDMI、音频接口,防护ESD及插拔浪涌;
  3. 物联网模块:智能传感器、无线通信模块(WiFi、蓝牙),需小体积防护且不影响信号传输;
  4. 车载电子(部分场景):车载信息娱乐系统、传感器节点,可在-40℃~+85℃环境下工作;
  5. 医疗电子:小型医疗设备的信号接口,需低漏电流及可靠防护,避免干扰医疗信号。

五、符合国际防护标准

SM24.TCT严格遵循电磁兼容(EMC)核心标准,确保电路通过合规测试:

  • IEC 61000-4-2:静电放电(ESD)防护,可应对接触放电8kV、空气放电15kV的典型测试要求;
  • IEC 61000-4-4:电快速瞬变脉冲群(EFT)防护,满足2kV/5kHz的测试等级;
  • IEC 61000-4-5:浪涌(Surge)防护,可承受2kV(线-地)/1kA的浪涌冲击。

总结

SM24.TCT作为一款双向TVS二极管,凭借双向防护、宽温范围、低漏电流、小封装及多标准兼容的特性,成为敏感电子电路瞬态过压防护的高性价比选择。其适配工业、消费电子、物联网等多领域需求,可有效提升电路的抗干扰能力及可靠性,减少因瞬态冲击导致的元器件损坏。

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
