SMAJ26A-TR 产品概述

介绍

SMAJ26A-TR是一款由意法半导体（STMicroelectronics）制造的瞬态抑制二极管（TVS），设计用于保护电子设备免受电涌和瞬态电压的影响。它是一种单向齐纳二极管，具有高效的电压钳位特性，能有效地保护敏感的电子组件，广泛应用于汽车、工业控制、通讯设备等领域。

基本参数

SMAJ26A-TR的关键参数包括：

  • 单向通道：1
  • 反向断态电压（Vr）：典型值为26V
  • 击穿电压（Vbr）：最小值为28.9V，确保在高电压情况下能够及时钳位，保护后续电路不受损坏。
  • 电压 - 箝位（最大值）：在不同的峰值脉冲电流（Ipp）下，最大箝位电压为53.5V，这为电路提供了更高的安全保障。
  • 峰值脉冲电流：在10/1000µs下的最大峰值脉冲电流可达到43A（在8/20µs为参考），表明该器件可以承受较大的瞬态电流而不会损坏。
  • 功率 - 峰值脉冲：该元件的峰值脉冲功率为400W，能够在瞬态事件中快速消散能量，进一步保护负载。

工作环境与安装

  • 工作温度：SMAJ26A-TR的工作温度范围为-55°C至150°C，这使得该器件可以在恶劣环境下稳定工作，适应各种应用场景。
  • 安装类型：该器件采用表面贴装型（SMD）封装，方便在现代电路板上进行自动化装配。
  • 封装方式：封装形式为DO-214AC（SMA），使得该元件在紧凑空间中依然能够保持良好的热传导和电气性能。

应用领域

SMAJ26A-TR广泛应用于多个领域，其中主要包括：

  • 汽车电子：在车辆的电子控制单元（ECU）、传感器和其他敏感器件中，保护它们免受电源反转、电涌和静电放电（ESD）的影响。
  • 工业控制系统：提供可靠的瞬态电压抑制，保证控制系统的稳定性和可靠性。
  • 通讯设备：保护射频（RF）模块、数据通信接口免受电涌和瞬态过压的影响，确保稳定的数据传输。
  • 消费电子：在手机、电视、电脑及其配件中，防止由于外部电压波动导致的瞬间损坏。

性能优势

SMAJ26A-TR除了具有卓越的电压钳位能力外，其优越的工作温度范围也使其在高温及高应力的环境中表现出色。此外，这款器件还具备快速反应时间与高重复性，有效闭合电流路径，降低后续电路的故障风险。

总结

SMAJ26A-TR瞬态抑制二极管是保护电子设备的重要组件，尤其是在面对突发电压事件时。凭借其高峰值脉冲电流、宽广的工作温度范围和紧凑的SMD封装，SMAJ26A-TR已成为多种电气和电子应用中保护电路的可靠选择。无论是在自动化、工控还是消费电子领域，SMAJ26A-TR都以其卓越的性能和稳定性为设计工程师提供了更多的设计自由度，保证了设备的长期运行安全。

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
