5.0SMDJ36A 瞬态抑制二极管(TVS)产品概述

一、产品定位与核心价值

5.0SMDJ36A是美国力特(Littelfuse)推出的5kW功率等级单向瞬态抑制二极管(TVS),专为36V系统的过压防护设计,核心价值在于快速响应瞬态干扰、稳定钳位电压、低功耗适配,同时具备宽温工作能力,适配高密度表面贴装电路的防护需求。作为DO-214AB(SMCJ)封装的经典型号,该器件可有效抑制ESD(静电放电)、EFT(电快速瞬变脉冲群)等瞬态干扰,保护敏感电子元器件(如IC、MOSFET)免受损坏,广泛应用于工业控制、通信设备等对可靠性要求较高的场景。

二、基础参数与性能指标

该型号的核心参数可分为电性能、环境与合规三类,关键指标如下:

2.1 电性能核心参数

  • 过压防护基础:反向截止电压(Vrwm)=36V(正常工作时不导通,适配36V及以下系统);击穿电压(Vbr)=40V(典型触发阈值);钳位电压(Vc)=58.1V(峰值脉冲下的最大钳位电压,需低于被保护器件耐受极限);
  • 脉冲耐受能力:峰值脉冲功率(Ppp)=5kW(单次最大承受功率);峰值脉冲电流(Ipp)=86.1A(5kW功率下的脉冲电流);反向漏电流(Ir)=5μA(低漏特性,减少系统待机功耗);
  • 精度:电压参数公差为±5%(UNI单向型,批量一致性好)。

2.2 环境与合规参数

  • 工作温度范围:-65℃~+150℃(宽温设计,满足工业级极端温度需求);
  • 防护等级:符合IEC 61000-4-2标准(静电放电防护,适配EMC电磁兼容要求);
  • 环保合规:RoHS认证(无铅、无镉等有害物质)。

三、封装与物理特性

5.0SMDJ36A采用SMCJ封装(DO-214AB标准),属于表面贴装型小功率TVS,物理特性适配高密度电路:

  • 封装尺寸:约3.2mm(长)×1.6mm(宽)×1.0mm(高)(典型值),体积紧凑,支持密集PCB布局;
  • 焊接兼容性:支持回流焊工艺,无铅设计符合现代电子制造要求;
  • 极性标识:封装带色环端为负极(单向型需严格匹配正负极,避免防护失效)。

四、典型应用场景

该型号的参数特性使其适配多类中低压系统,核心应用场景包括:

  1. 工业控制:PLC、传感器接口、电机驱动电路的过压防护(宽温特性适配-40℃~+85℃的工业现场温度波动);
  2. 通信设备:基站射频模块、路由器/交换机的电源与信号端口防护(5kW功率可应对通信系统瞬态脉冲干扰);
  3. 消费电子:大功率电源适配器、智能家电控制电路防护(低漏电流减少待机功耗);
  4. 医疗设备:低功耗医疗仪器的信号与电源端口防护(符合宽温与可靠性要求)。

五、可靠性与选型注意事项

5.1 可靠性优势

  • 脉冲寿命:多次承受额定脉冲后,电性能参数变化率≤10%(符合Littelfuse可靠性测试标准);
  • 一致性:±5%电压公差确保批量应用时防护性能稳定,降低系统设计风险;
  • ESD防护:满足IEC 61000-4-2标准,典型可承受8kV接触放电、15kV空气放电。

5.2 选型与使用注意

  1. 系统匹配:Vrwm需≥系统最大工作电压(如24V系统可选36V Vrwm型号),钳位电压需≤被保护器件最大耐受电压;
  2. 并联安装:TVS需与被保护电路并联(电源端并联于地与电源之间,信号端并联于信号与地之间),确保瞬态脉冲快速泄放;
  3. 焊接工艺:回流焊峰值温度≤260℃、时间≤30s,避免过温损坏器件。

六、总结

5.0SMDJ36A作为Littelfuse的经典TVS型号,以5kW功率、宽温工作、低漏电流为核心优势,适配36V系统的过压防护需求,广泛覆盖工业、通信等领域。其SMCJ封装的紧凑设计与RoHS合规性,使其成为高密度电路防护的高性价比选择,可有效提升电子系统的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.

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.
