SM36.TCT TVS二极管产品概述

一、产品核心身份与定位

SM36.TCT是SEMTECH(世芯科技) 推出的一款双路ESD防护TVS二极管,属于瞬态电压抑制(TVS)器件范畴。其核心作用是为电子电路提供静电放电(ESD) 和瞬态过电压 的快速防护,避免敏感元器件(如MCU、传感器、接口芯片等)因过压冲击损坏,广泛适用于消费电子、通信、工业控制等领域的小型化设计场景。

二、关键电气参数详解

SM36.TCT的核心电气参数精准匹配低/中压电路的防护需求,关键指标如下:

  1. 反向击穿电压(Vbr):36V(典型值)—— 器件在反向偏置下开始导通的电压,确保正常工作时(电路电压≤30V)不影响信号传输或电源稳定性,留有安全裕量。
  2. 钳位电压(Vc):60V(最大值)—— 当遭遇瞬态过电压(如ESD、浪涌)时,器件快速导通并将电压钳位在60V以下,有效保护后端电路。
  3. 通道数:双路独立防护—— 集成两个并行的ESD防护通道,可同时防护两路信号(如USB D+/D-)或电源线路,无需额外并联器件,节省PCB空间。
  4. 峰值脉冲功率(Pppm):500W(典型值,8/20μs脉冲)—— 可承受多次高强度瞬态冲击,符合IEC 61000-4-2等国际标准的ESD测试要求(接触放电±8kV、空气放电±15kV)。
  5. 反向漏电流(IR):≤1μA(@30V反向偏置)—— 低漏电流特性确保器件在静态下不消耗额外功率,不影响电路效率。

三、封装与物理特性

SM36.TCT采用SOT23-3小型表面贴装封装,适配高密度PCB设计:

  • 封装尺寸:约2.9mm(长)×1.6mm(宽)×1.1mm(高),体积紧凑,适合便携设备(如手机、耳机)的窄空间布局。
  • 引脚配置:3引脚设计,引脚1、3为防护通道端,引脚2为公共地端(GND),布线简单,可快速集成到现有电路。
  • 温度范围:商业级(-40℃+85℃)/工业级(-55℃+125℃,可选)—— 覆盖多数应用环境的温度需求,满足户外设备、工业控制器的可靠性要求。

四、典型应用场景

SM36.TCT的双路防护特性与小封装优势,使其成为以下场景的理想选择:

  1. 消费电子接口防护:手机、平板、笔记本的USB(Type-C/A)、HDMI、音频接口的ESD防护,避免用户插拔时的静电损坏。
  2. 通信设备端口防护:路由器、交换机的以太网端口(RJ45)、射频模块(RF)的瞬态过电压防护,保障数据传输稳定。
  3. 工业控制传感器防护:PLC、温度/压力传感器的信号输入端口防护,应对工业环境中的电磁干扰(EMI)和浪涌冲击。
  4. 便携设备电源防护:智能手表、蓝牙耳机的电池充电端口防护,防止充电过程中的过压损坏。

五、品牌与可靠性保障

SEMTECH作为全球模拟半导体领域的领先厂商,其SM36.TCT具备可靠的品质保障:

  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无卤,适配绿色电子产品设计。
  • 可靠性测试:通过高温存储、温度循环、ESD多次冲击等严苛测试,确保产品在全生命周期内稳定工作。
  • 应用支持:SEMTECH提供详细的 datasheet 与应用指南,协助工程师快速完成电路集成与调试。

六、选型与应用注意事项

为确保SM36.TCT的防护效果,需注意以下要点:

  1. 电压匹配:后端电路的工作电压需≤30V(低于Vbr 36V,留6V裕量),避免器件误导通。
  2. 布线优化:器件需尽可能靠近被防护的接口或元器件,减少引线电感(引线电感会降低钳位效果);公共地端需可靠连接到系统地。
  3. 多通道扩展:若需防护多路信号,可采用多颗SM36.TCT并联(或选择多通道TVS),但需注意散热设计。

SM36.TCT凭借双路防护、小封装、高可靠性等优势,成为中低压电路ESD防护的高性价比选择,广泛应用于各类电子设备的接口与电源防护场景。

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
