SMCJ1.5KE39A-TP TVS二极管产品概述

SMCJ1.5KE39A-TP是MCC(美微科)推出的单向瞬态抑制二极管(TVS),采用SMC(DO-214AB)表面贴装封装,专为电子电路的瞬态过压保护设计,具备宽温范围、高脉冲功率等核心优势,适用于工业控制、汽车电子等严苛应用场景。

一、产品基本信息

  • 品牌:MCC(美微科),专业半导体器件制造商,产品覆盖保护器件、功率器件等领域,品质符合工业及汽车级标准;
  • 产品类型:单向TVS瞬态抑制二极管;
  • 封装形式:SMC(DO-214AB)表面贴装,无引线设计,兼容回流焊工艺,适合高密度PCB布局;
  • 核心定位:针对12V/24V系统的过压保护,抑制雷电、静电放电(ESD)、开关浪涌等瞬态干扰。

二、核心电气参数详解

SMCJ1.5KE39A-TP的电气参数经过严格测试,关键指标如下:

  1. 截止与击穿特性:
    反向截止电压(Vrwm)=37.1V(最大反向工作电压,正常工作时不超过此值);击穿电压(Vbr)=41V(反向击穿电压,略高于Vrwm,保证保护启动阈值稳定)。
  2. 钳位与脉冲能力:
    钳位电压(Vc)=53.9V(浪涌时的峰值钳位电压,将过压限制在安全范围);峰值脉冲电流(Ipp)=28.2A(8/20μs脉冲波形下的最大浪涌电流);峰值脉冲功率(Ppp)=1.5kW(Vc与Ipp的乘积,体现浪涌承受能力)。
  3. 静态特性与温度范围:
    反向漏电流(Ir)=5μA(Vrwm下的反向漏电流,低功耗不影响电路正常工作);工作温度范围=-55℃~+175℃(宽温覆盖工业、汽车等极端环境)。

三、封装与机械特性

SMC(DO-214AB)封装是TVS器件的主流表面贴装封装之一,具备以下特点:

  • 尺寸紧凑:典型尺寸为长5.8mm×宽4.5mm×高2.3mm,节省PCB空间,适合小型化设备;
  • 工艺兼容:无引线设计,支持回流焊、波峰焊等自动化贴装工艺,生产效率高;
  • 机械强度:封装材料为耐高温塑料,抗冲击、抗振动性能优异,适应 harsh环境。

四、典型应用场景

基于其宽温范围、高脉冲功率特性,SMCJ1.5KE39A-TP广泛应用于以下领域:

  1. 工业控制:PLC(可编程逻辑控制器)、传感器接口、伺服驱动器的过压保护,应对工业现场的浪涌干扰;
  2. 汽车电子:车载通信模块(CAN/LIN总线)、传感器(如胎压监测、温度传感器)、DC-DC转换器的瞬态保护,满足汽车级温度要求;
  3. 通信设备:基站、路由器、交换机的电源端口及信号端口保护,抑制雷电浪涌;
  4. 电源系统:电池管理系统(BMS)、UPS电源、DC电源的浪涌抑制,保护后端敏感器件;
  5. 高可靠性消费电子:工业级手持设备、医疗设备的过压防护。

五、性能优势总结

SMCJ1.5KE39A-TP相比普通TVS器件,具备以下核心优势:

  • 宽温可靠性:-55℃~+175℃的工作温度范围,覆盖大部分工业及汽车应用场景;
  • 强浪涌承受:1.5kW峰值脉冲功率,可有效抑制强瞬态浪涌(如雷电、开关冲击);
  • 低功耗设计:5μA反向漏电流,静态下几乎不消耗功率,不影响电路正常工作;
  • 快速响应:TVS典型响应时间为ns级(小于1ns),可瞬间钳位过压,保护敏感器件;
  • 自动化适配:SMC表面贴装封装,适合大规模自动化生产,降低制造成本。

该产品符合RoHS环保标准,无铅无卤,满足现代电子设备的环保要求,是工业及汽车电子领域过压保护的可靠选择。

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
