5.0SMDJ100A 瞬态抑制二极管(TVS)产品概述

5.0SMDJ100A是DOWO(东沃) 推出的单向瞬态抑制二极管(TVS),专为电路过压防护设计,凭借精准的钳位特性、宽温适应能力及紧凑封装,广泛应用于工业、汽车、通信等对可靠性要求较高的领域。

一、产品定位与核心类别

5.0SMDJ100A属于单向TVS器件,区别于双向TVS(适用于正负脉冲双向防护),主要针对电源正负极明确的电路,核心作用是快速吸收瞬态浪涌能量(如雷电、开关干扰、ESD等),将电路电压钳位在安全范围内,保护后端敏感元器件(如MCU、传感器、通信芯片)不被损坏。

与压敏电阻等其他保护器件相比,TVS具有ns级响应速度(压敏电阻为μs级)、钳位电压稳定(受脉冲电流影响小)、漏电流低等优势,是现代电子设备过压防护的主流选择。

二、关键电气参数深度解析

5.0SMDJ100A的参数设计精准匹配多场景需求,核心参数意义如下:

1. 电压类参数

  • 反向截止电压(Vrwm=100V):电路正常工作时,器件反向可承受的最大电压,此时器件处于截止状态,不影响信号/电源传输;
  • 击穿电压(Vbr=111V):反向电压超过此值时,器件进入低阻击穿态,开始吸收浪涌能量;
  • 钳位电压(162V):峰值脉冲电流下的最大电压限制值(核心保护指标),确保后端器件电压不超额定值(如MCU典型耐压150V~180V)。

2. 电流与功率参数

  • 峰值脉冲电流(Ipp=30.86A):10/1000μs浪涌波形下(标准浪涌测试波形:前沿10μs、半峰值时间1000μs),器件可承受的最大脉冲电流;
  • 峰值脉冲功率(Ppp=5kW):10/1000μs波形下的峰值浪涌功率(计算:162V×30.86A≈5000W),体现器件浪涌承受能力;
  • 反向漏电流(Ir=5μA):反向截止电压下的漏电流,数值极小,不影响电路正常工作。

3. 温度参数

  • 工作温度范围(-55℃~+150℃):覆盖工业级(-40℃+85℃)和汽车级(-55℃+125℃),可适应极端环境(如高温车载、低温工业现场)。

三、封装与可靠性设计

5.0SMDJ100A采用SMCJ(DO-214AB)封装,具备以下优势:

  • 紧凑尺寸:参考标准尺寸(长2.7mm×宽1.9mm×高1.1mm),适合高密度PCB布局(如汽车电子、通信模块);
  • 焊接兼容性:支持回流焊、波峰焊,生产效率高,替换进口同类产品无需调整PCB;
  • 可靠性设计:东沃采用优化的封装工艺,提升抗振动、耐温冲击能力,符合IEC 61000-4-5浪涌测试标准。

四、典型应用场景

5.0SMDJ100A的参数特性使其适配多领域过压防护需求:

  1. 工业控制:PLC输入输出端口、伺服驱动器、传感器接口,抑制雷电浪涌或开关干扰;
  2. 汽车电子:车载CAN/LIN总线、胎压监测模块、ADAS传感器,宽温适应车载环境(-40℃~+85℃常见,150℃满足高温工况);
  3. 通信设备:路由器、交换机、光模块的电源/信号端口,抑制ESD和浪涌;
  4. 电力监测:智能电表、互感器的电压输入保护,防止雷击过压;
  5. 消费电子:高端显示器、机顶盒的电源模块,提升产品可靠性。

五、品牌与品质保障

DOWO(东沃)是国内专注于过压保护器件的制造商,5.0SMDJ100A具备以下品质优势:

  • 认证齐全:通过ISO 9001、IATF 16949(汽车级)认证,符合RoHS 6、REACH环保要求;
  • 参数一致性:批量生产偏差小,确保电路保护效果稳定;
  • 性价比优势:替代进口同类产品(如Littelfuse SMCJ100A),交期短、成本低,提供技术支持与样品测试。

5.0SMDJ100A凭借精准的保护参数、紧凑封装、宽温可靠性及高性价比,成为多领域过压防护的优选器件,满足不同场景下的浪涌抑制需求。

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
