SMAJ6.5A瞬态抑制二极管(TVS)产品概述

SMAJ6.5A是瑞隆源(RUILON)推出的贴片式瞬态抑制二极管(TVS),专为电路瞬态过压防护设计,具备高抗脉冲能力、宽温适应性等核心优势,广泛覆盖消费电子、工业控制、汽车电子等多领域应用。

一、产品基本信息

  • 品牌:RUILON(瑞隆源),国内专业过压保护器件制造商,产品涵盖TVS、压敏电阻等系列,以高可靠性著称;
  • 类型:单向瞬态抑制二极管(TVS),通过反向击穿特性快速吸收瞬态浪涌能量,阻断过压对后端元件的损害;
  • 封装:DO-214AC(贴片封装),尺寸紧凑(典型值2.5mm×1.5mm×1.0mm),支持自动化表面贴装(SMT),适配高密度电路布局;
  • 型号标识:“SMAJ”代表贴片TVS系列,“6.5”对应反向截止电压核心参数,“A”通常表示单向导通特性(仅反向吸收浪涌)。

二、核心电气参数详解

SMAJ6.5A的电气参数针对瞬态防护需求优化,关键参数及实际意义如下:

  1. 反向截止电压(Vrwm):6.5V
    电路正常工作时反向允许施加的最大电压,需匹配电路工作电压(如3.3V/5V系统),超过该值器件将进入击穿状态;
  2. 钳位电压(Vc):11.2V
    当出现10/1000μs浪涌脉冲时,器件将电压钳位至该值,确保后端敏感元件(如MCU、传感器)不被过压击穿;
  3. 峰值脉冲电流(Ipp):35.7A@10/1000μs
    10/1000μs为国际通用浪涌波形(前沿10μs、半峰值时间1000μs),该参数表示器件可承受的最大瞬态电流,能有效吸收强浪涌;
  4. 峰值脉冲功率(Ppp):400W@10/1000μs
    对应脉冲波形下的最大功率容量,直接反映抗浪涌能力,400W可满足多数中低功率电路的防护需求;
  5. 击穿电压(Vbr):7.98V
    反向电压达到该值时器件导通并吸收浪涌,击穿电压稳定(典型值±5%范围),防护一致性优异;
  6. 反向漏电流(Ir):500μA@Vrwm
    正常工作电压下的反向漏电流,500μA属于低漏电流范围,可降低电路静态功耗,不影响系统运行。

三、关键性能特点

  1. 高抗浪涌能力:400W峰值脉冲功率与35.7A峰值脉冲电流,可有效抑制雷电感应、静电放电(ESD)、开关浪涌等瞬态干扰;
  2. 宽温度适应性:工作温度范围-55℃~+150℃,符合工业级标准,可在极端高低温环境(如汽车发动机舱、户外工业设备)稳定工作;
  3. 快速响应速度:TVS典型响应时间为ns级(<1ns),能在瞬态过压出现时立即导通,保护后端元件;
  4. 低静态功耗:500μA反向漏电流,对电路静态功耗影响极小,适合电池供电的便携设备;
  5. 紧凑封装设计:DO-214AC贴片封装体积小,节省PCB空间,适配高密度电路布局(如智能手机、智能穿戴);
  6. 高可靠性:封装采用耐高温环氧树脂,抗振动、耐冲击性能优异,长期使用后参数漂移小,满足高可靠性需求。

四、典型应用场景

SMAJ6.5A适配多种电压系统的瞬态防护,典型应用包括:

  1. 消费电子:智能手机、平板、笔记本的USB接口、充电端口、音频接口防护,防止静电或浪涌损坏主板;
  2. 工业控制:PLC模块、传感器节点、电机驱动电路的电源端口防护,应对工业现场开关浪涌与电磁干扰;
  3. 汽车电子:车载显示屏、胎压监测传感器、车载通信接口的过压防护,适配汽车级宽温要求;
  4. 通信设备:路由器、交换机、基站的以太网接口、电源端口防护,抑制雷电感应与浪涌干扰;
  5. 电源系统:DC-DC转换器、电池充电电路、UPS电源的输出端防护,保护后端负载免受瞬态过压影响。

五、可靠性与应用注意事项

  1. 温度稳定性:-55℃~+150℃范围内,击穿电压与漏电流变化量<10%,防护性能稳定;
  2. 焊接要求:SMT焊接温度需控制在260℃以内(峰值),焊接时间不超过10秒,避免损坏器件;
  3. 参数匹配:Vrwm需高于电路正常工作电压10%~20%,钳位电压需低于后端元件最大耐压值;
  4. 并联扩展:若需更高抗浪涌能力,可采用多个器件并联(需均流设计),提升总脉冲功率容量。

SMAJ6.5A凭借高性价比、宽温适应性与紧凑封装,成为中低电压电路瞬态防护的常用器件,可满足多数消费电子、工业与汽车应用的防护需求。

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.
