SMA6J5.0CA 瞬态抑制二极管(TVS)产品概述

一、产品核心定位与类别

SMA6J5.0CA是一款双向瞬态抑制二极管(TVS),属于过压防护器件范畴,核心作用是快速抑制电路中的瞬态浪涌电压(如静电放电ESD、雷击感应浪涌、开关瞬态干扰等),将电压钳位在安全范围内,避免后级敏感电子元件(如MCU、传感器、通信芯片等)因过压损坏。该器件以小封装、高功率容量为特点,适配高密度PCB设计的电压防护场景。

二、关键电气参数详解

SMA6J5.0CA的电气参数针对5V系统防护优化,核心参数及实际意义如下:

  • 极性:双向:可同时防护电路正、负方向的浪涌干扰,无需区分正负极安装,简化电路设计;
  • 反向截止电压(Vrwm):5V:正常工作状态下,反向电压不超过5V时器件保持截止,不影响电路正常供电(适配5V典型工作电压的系统);
  • 钳位电压:9.2V:浪涌到来时,器件快速导通并将电压钳位至9.2V(远低于多数敏感元件的耐压极限,如MCU耐压通常≤10V),有效保护后级电路;
  • 峰值脉冲电流(Ipp):65.2A:可承受的最大浪涌电流峰值,满足一般工业、消费电子场景的浪涌冲击需求;
  • 峰值脉冲功率(Ppp):600W:浪涌事件中器件可吸收的最大功率,确保多次浪涌后仍能稳定工作;
  • 击穿电压:6.4V:反向击穿的典型电压,接近工作电压上限,保证浪涌到来时器件快速响应(ns级);
  • 反向电流(Ir):800uA:反向截止电压下的漏电流,数值极小,正常工作时不额外消耗电路功率。

三、封装与物理特性

该器件采用SMA封装(DO-214AC),是贴片式表面贴装封装的典型代表,具有以下优势:

  • 体积小巧:封装尺寸约为2.0mm×3.8mm×1.5mm,适配高密度PCB布局(如小型化消费电子、物联网模块);
  • 焊接便捷:引脚间距合理,兼容回流焊、波峰焊等自动化焊接工艺,适合批量生产;
  • 环保无铅:符合RoHS、REACH等国际环保标准,满足绿色制造要求。

四、应用场景推荐

结合参数特性,SMA6J5.0CA适用于以下典型场景:

  1. 5V供电系统防护:如智能手机、平板的USB接口、电源输入端口,防止充电时的浪涌干扰;
  2. 工业控制领域:PLC输入输出模块、传感器节点的浪涌防护(适配工业环境的宽温需求);
  3. 汽车电子:车载MCU、胎压监测传感器、车载通信接口的瞬态抑制(工作温度覆盖汽车级要求);
  4. 通信设备:路由器、交换机的RJ45接口、电源端口防护;
  5. 物联网模块:低功耗无线模块(如LoRa、WiFi)的电源与信号接口防护。

五、可靠性与环境适应性

SMA6J5.0CA具备优异的可靠性与环境适应性:

  • 宽温工作范围:-55℃~+150℃,可适应极端环境(如低温工业场所、汽车发动机舱高温环境);
  • 低功耗稳定:反向漏电流仅800uA,正常工作时不影响电路效率;
  • 抗浪涌寿命长:多次承受额定浪涌冲击后,性能无明显衰减,满足长期使用需求;
  • 响应速度快:TVS典型响应时间为ns级,可瞬间抑制瞬态干扰(远快于压敏电阻等器件)。

六、品牌与质量保障

SMA6J5.0CA由国内知名半导体厂商DOWO(东沃) 研发生产,东沃专注于过压防护器件领域多年,产品具备:

  • 严格的质量管控:通过温度循环、湿热测试、浪涌寿命测试等可靠性验证;
  • 环保合规:符合RoHS、REACH及无卤素要求;
  • 稳定供货:拥有成熟的生产线,可满足批量订单需求。

该器件以高性价比、适配性强的特点,成为5V系统过压防护的优选器件之一。

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
