SMAJ26CA(RUILON)瞬态抑制二极管产品概述

SMAJ26CA是瑞隆源(RUILON)推出的一款双向瞬态抑制二极管(TVS),采用DO-214AC(SMA)表面贴装封装,专为电路中的瞬态过压防护设计,能有效应对静电放电(ESD)、电快速瞬变脉冲群(EFT)及开关浪涌等干扰,广泛应用于消费电子、工业控制、通信等领域。

一、产品基本定位与封装特性

作为一款中低压TVS器件,SMAJ26CA采用DO-214AC封装(俗称SMA封装),属于小型表面贴装结构,体积紧凑(约2.7mm×1.7mm×1.1mm),适配自动化贴片生产线,同时便于在高密度电路板上布局。其核心为双向极性设计,无需区分正负引脚,简化了电路设计与焊接流程,降低了安装错误风险。

二、核心电性能参数解析

SMAJ26CA的电性能参数针对性强,能满足多数低压电路的防护需求:

  • 反向截止电压(Vrwm)26V:电路正常工作时,反向电压不超过26V则器件保持截止,不影响原有电路信号传输;
  • 击穿电压(Vbr)33.2V:当瞬态过压超过33.2V时,器件快速击穿导通(响应时间达纳秒级),瞬间将过压能量泄放;
  • 钳位电压(Vc)42.1V:击穿导通后,能将过压钳位在42.1V左右,保护后端敏感元器件(如MCU、传感器)不被高压损坏;
  • 峰值脉冲功率(Ppp)400W:以10/1000μs脉冲波形测试,可承受最大400W的瞬态功率冲击,覆盖常见浪涌场景;
  • 峰值脉冲电流(Ipp)9.5A:对应400W功率的脉冲电流容量,能快速泄放瞬态能量;
  • 反向漏电流(Ir)1μA:在Vrwm下漏电流极小,不消耗额外功耗,避免影响电路正常工作。

三、电磁防护能力与合规标准

SMAJ26CA通过了IEC 61000-4-2(静电放电) 和 IEC 61000-4-4(电快速瞬变脉冲群) 两项国际标准测试,防护能力覆盖:

  • 静电放电(ESD):可应对人体接触/空气放电(±8kV/±15kV典型),避免设备因静电损坏;
  • 电快速瞬变脉冲群(EFT):能抑制快速重复的脉冲干扰(如开关浪涌、电机启动干扰),确保电路稳定运行。 这些标准认证保证了产品在实际应用中的可靠性,适配工业、通信等对电磁兼容要求较高的场景。

四、工作环境与应用场景

SMAJ26CA的工作温度范围为-55℃~+150℃,宽温特性使其能适应极端环境(如工业现场的高温、低温,汽车电子的宽温工况)。结合其双向防护、小体积的特点,主要应用场景包括:

  • 消费电子:手机、平板、笔记本电脑的USB、HDMI等接口防护;
  • 工业控制:PLC模块、传感器、电机驱动电路的过压防护;
  • 通信设备:路由器、交换机、基站的信号接口与电源防护;
  • 汽车电子:低压辅助电路(如车灯、中控)的瞬态干扰防护(适配宽温需求)。

五、产品优势总结

SMAJ26CA的核心优势在于平衡了防护能力与应用便捷性:双向极性简化设计、小体积适配高密度布局、宽温范围覆盖 harsh环境、低漏电流不影响电路功耗,同时满足多项国际电磁防护标准,是低压电路瞬态过压防护的高性价比选择。

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
