SMAJ60A TVS二极管产品概述

一、产品基本定位与核心属性

SMAJ60A是晶导微电子推出的单向瞬态抑制二极管(TVS),采用DO-214AC(SMA)表面贴装封装,专为电子电路中的过压保护设计——可快速抑制静电放电(ESD)、雷击感应、开关尖峰等瞬态浪涌,避免后端敏感元器件(如IC、MOS管、传感器)被过压击穿。该器件极性为单向,适用于单方向电压尖峰的抑制场景,在消费电子、工业控制、汽车电子等领域具有广泛应用潜力。

二、关键电气参数与性能解析

SMAJ60A的电气参数兼顾保护能力与电路兼容性,核心参数及实际意义如下:

(1)电压类核心参数

  • 反向截止电压(Vₐₙₘ):60V
    器件正常工作时反向可承受的最大直流电压(无击穿)。若电路正常工作电压低于60V,该器件保持高阻态,不影响电路功能。
  • 击穿电压(Vᵦᵣ):73.7V
    当反向电压超过此值时,器件快速击穿并进入低阻导通状态,立即启动保护机制,将电压钳位在安全范围。
  • 钳位电压(Vᶜ):96.8V
    峰值脉冲电流下的最大钳位电压,直接决定后端电路的安全上限——浪涌发生时,SMAJ60A可将电路电压限制在96.8V以内,避免敏感器件损坏。

(2)电流与功率参数

  • 峰值脉冲电流(Iₚₚ):4.1A(10/1000μs波形)
    采用10/1000μs(前沿10μs、半值宽1000μs)标准浪涌波形测试,器件可承受的最大峰值脉冲电流为4.1A,满足多数中低功率电路的浪涌抑制需求。
  • 峰值脉冲功率(Pₚₚ):400W(同波形)
    对应脉冲功率能力,可快速耗散瞬态浪涌能量,避免器件自身损坏。

(3)其他关键参数

  • 反向漏电流(Iᵣ):1μA
    正常反向电压下的漏电流极低,不会对低功耗、敏感电路(如传感器、通信接口)造成额外功耗或干扰。
  • 工作温度范围:-65℃~+150℃
    宽温特性使其可适应极端环境(如汽车发动机舱、工业高温车间),满足高低温场景下的稳定保护需求。

三、封装与物理特性

SMAJ60A采用DO-214AC(SMA)表面贴装封装,具有三大实用优势:

  1. 小型化设计:封装尺寸紧凑(典型值:长2.3mm×宽1.5mm×高1.0mm),适合高密度PCB布局(如手机、智能穿戴等便携设备);
  2. 贴装便捷:引脚清晰,兼容常规SMT焊接工艺(如260℃回流焊),适合自动化量产;
  3. 环保可靠:符合RoHS无铅标准,耐焊接热冲击,长期可靠性稳定。

四、典型应用场景

结合参数特性,SMAJ60A的核心应用场景包括:

  1. 消费电子:手机、平板、笔记本的USB充电口、HDMI接口、耳机接口,抑制静电与浪涌;
  2. 汽车电子:车载充电器、CAN总线节点、胎压传感器、车灯驱动电路,适应-65℃~+150℃的汽车环境;
  3. 工业控制:PLC输入输出端口、传感器模块、电机驱动电路,防止开关浪涌或雷击感应损坏;
  4. 通信设备:路由器、交换机的以太网接口、无线模块,抑制静电与浪涌干扰;
  5. 电源模块:DC-DC转换器、开关电源的输出端,保护后端MCU、存储芯片等负载。

五、品牌与可靠性说明

晶导微电子作为国内功率半导体主流厂商,其TVS系列产品经过严格可靠性测试(高温存储、温度循环、湿度老化、焊接热冲击等),符合GB/T 15925、IEC 61000-4-2等行业标准。SMAJ60A具有批次一致性好、参数离散性小的特点,可满足量产应用中的稳定性需求,降低客户选型与验证成本。

该器件凭借紧凑封装、宽温能力与精准保护参数,成为中低功率电路过压保护的高性价比选择。

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
