SMAJ26AQ 产品概述

一、产品简介

SMAJ26AQ 是扬杰(YANGJIE)生产的一款单向瞬态抑制二极管(TVS),封装为 DO-214AC(SMA)。器件设计用于抑制电源线和数据线上的瞬态过电压,提供快速钳位并保护后端电路免受浪涌、电感耦合或静电放电引起的损伤。该型号在 10/1000 μs 浪涌波形下的峰值脉冲功率为 400W,适合工业级和通信类抗干扰设计。

二、主要参数

  • 极性:单向(反向工作时为稳压钳位特性)
  • 反向额定电压 Vrwm:26 V
  • 击穿电压 Vbr(标称):31.9 V
  • 钳位电压 Vc(Ipp 条件下):42.1 V
  • 峰值脉冲电流 Ipp:9.5 A(10/1000 μs)
  • 峰值脉冲功率 Ppp:400 W(10/1000 μs)
  • 反向漏电流 Ir:约 1 μA(在 Vrwm 条件下)
  • 工作温度范围:-55 ℃ ~ +175 ℃
  • 封装:DO-214AC(SMA)

三、主要特性

  • 快速响应,对纳秒级瞬态具有良好吸收能力;
  • 低反向漏电流,适用于对静态功耗敏感的电路;
  • 单向结构,正向导通特性明确,适用于直流电源和单极性信号线保护;
  • 宽温度范围与高温稳定性,适合严苛环境应用;
  • SMA 封装方便自动贴片与批量生产。

四、典型应用场景

  • 电源输入端浪涌保护(24 V 左右系统);
  • 通信接口与数据线过压抑制;
  • 工业控制设备、PLC、电机驱动及传感器接口;
  • 汽车电子(非车规级需确认额外认证)与消费电子的瞬态保护模块。

五、工程使用建议

  • Vrwm 的选择:应高于系统正常工作电压且留有裕量(通常选择略高于最大工作电压),以避免在正常波动下进入击穿。
  • 布局注意:元器件应尽量靠近被保护引脚放置,连接线短且阻抗低以保证最快钳位响应;在高能量浪涌场合建议在器件附近增加散热铜箔以利热量扩散。
  • 浪涌处理:Ipp 与 Ppp 数据基于单次 10/1000 μs 波形测试,重复冲击或多次冲击需按热循环和能量累积进行降额设计。
  • 焊接与可靠性:遵循厂家推荐的回流焊温度曲线,避免超温导致封装或硅片退化;长期工作在高温环境时注意热应力与寿命评估。

六、质量与选型提示

SMAJ26AQ 具有低漏电、稳定的击穿和钳位特性,适合需要高能量吸收且对成本与封装尺寸有要求的场合。选型时应确认实际浪涌能量与钳位电压对下游电路(尤其是敏感芯片电压容忍度)的影响,并在必要时与高能量 TVS 或配套熔丝、电感结合以实现系统级保护。

七、包装与采购信息

  • 品牌:YANGJIE(扬杰)
  • 型号:SMAJ26AQ
  • 封装:DO-214AC(SMA),适合 SMT 组装与批量生产。
    如需批量采购或样品验证,建议向供应商索取完整器件数据手册(Datasheet)与可靠性测试报告,以便在具体应用中进行更精确的热、电和机械验证。

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
