SMCJ6.0A TVS二极管产品概述

SMCJ6.0A是晶导微电子推出的一款表面贴装瞬态电压抑制(TVS)二极管,采用SMC(DO-214AB)封装,专为低电压电路的瞬态过压防护设计,可有效抑制雷击浪涌、静电放电(ESD)及电源瞬态干扰,保护敏感电子元器件免受损坏。

一、产品基本属性

  1. 核心类型:瞬态电压抑制二极管(TVS),属于过压保护器件;
  2. 品牌与厂商:晶导微电子,国内功率半导体领域的主流供应商;
  3. 封装形式:SMC(DO-214AB)表面贴装封装,尺寸紧凑,适配自动化贴装;
  4. 功能定位:针对6V级以下低电压系统的瞬态过压防护,实现“快响应、低钳位”的保护效果。

二、核心电气参数解析

SMCJ6.0A的电气参数经过优化,精准匹配低电压电路的防护需求,关键参数及意义如下:

  1. 反向截止电压(Vrwm):6V
    指器件在正常工作状态下,反向偏置时不导通的最大电压,适配5V、6V等低电压供电系统(略高于系统工作电压,避免误触发);
  2. 钳位电压:10.3V
    当遭遇瞬态过压时,器件快速击穿并将电压钳制在10.3V以下,确保后级电路(如MCU、传感器)的耐压不被突破;
  3. 峰值脉冲电流(Ipp):145.7A@10/1000us
    10/1000us是国际通用的浪涌波形标准(上升时间10us,半峰值时间1000us),该参数表示器件可承受的最大单次脉冲电流,能应对强浪涌冲击;
  4. 峰值脉冲功率(Ppp):1.5kW@10/1000us
    对应浪涌波形下的最大脉冲功率,直接反映器件的浪涌耐受能力,1.5kW可覆盖多数消费电子、工业设备的浪涌场景;
  5. 击穿电压:7.37V
    反向击穿的典型值,介于截止电压(6V)和钳位电压(10.3V)之间,确保器件在过压时快速响应(ns级响应时间);
  6. 反向电流(Ir):800uA
    反向截止状态下的漏电流,数值低,对系统功耗影响极小;
  7. 工作温度范围:-55℃~+150℃
    宽温设计,可适应工业环境(低温、高温)、车载场景(部分应用)等恶劣温度条件。

三、封装与可靠性设计

  1. SMC封装优势:
    SMC(DO-214AB)属于小型表面贴装封装,体积约为2.9mm×2.4mm×1.0mm,适配高密度PCB设计;同时该封装散热性能良好,可快速 dissipate 脉冲功率带来的热量;
  2. 可靠性保障:
    晶导微电子采用成熟的芯片制造工艺,器件可多次承受脉冲冲击(无累计损伤),符合RoHS环保标准,且经过高低温循环、老化测试,确保批量应用的稳定性。

四、典型应用场景

SMCJ6.0A的参数特性使其广泛适用于以下低电压系统:

  1. 消费电子:手机、平板、笔记本电脑的充电端口(USB Type-C、Micro-USB)过压防护,防止充电器浪涌损坏电池或主板;
  2. 工业控制:PLC(可编程逻辑控制器)的输入输出端口、传感器接口的浪涌防护,应对现场电磁干扰;
  3. 通信设备:路由器、交换机的以太网端口(10/100M)、串口(RS485)的ESD及浪涌防护;
  4. 汽车电子(辅助):车载低电压传感器(如胎压监测)、小型控制器的过压防护(需结合整车EMC要求)。

五、总结与适用价值

SMCJ6.0A作为一款高性价比的TVS二极管,通过精准的参数设计(6V截止电压、10.3V钳位电压)、强浪涌耐受能力(1.5kW峰值功率)及宽温可靠性,为低电压电路提供了可靠的瞬态过压防护方案。其SMC封装适配自动化生产,适合批量应用于消费电子、工业控制等领域,是替代进口同类型器件的优质选择。

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
