SMAJ26CA 产品概述

概要

SMAJ26CA 是一种由 MDD 品牌生产的静电和浪涌保护(TVS/ESD)二极管,专门设计用于保护电子设备免受静电放电(ESD)和瞬时浪涌电流的损害。以下是对此产品的详细介绍。

基础参数

  • 击穿电压(Vc): 31.9V
    • 这是指在正常工作条件下,TVS 二极管开始导通并吸收过载能量的电压阈值。
  • 反向截止电压(Vrwm): 26V
    • 这是指在反向偏置条件下,TVS 二极管能够承受的最大电压,不会发生击穿或破坏。
  • 反向漏电流(Ir): 1uA
    • 在反向截止状态下,通过 TVS 二极管的微小电流,表示其在正常工作状态下的漏电特性。
  • 峰值脉冲功率(Ppp): 400W
    • 这表示 TVS 二极管在短时间内(通常为几微秒)能够吸收和分散的最大能量。
  • 峰值脉冲电流(Ipp): 9.5A
    • 这是指在峰值脉冲条件下,通过 TVS 二极管的最大电流。
  • 工作温度范围: -65℃ ~ +150℃
    • 表示该设备可以在极端温度条件下稳定运行。
  • 最大钳位电压: 42.1V
    • 当过载发生时,TVS 二极管会将过载电压钳制在这个水平,防止设备受到进一步损害。

类型和封装

  • 类型: TVS(Transient Voltage Suppressor)
    • 专门用于保护电子设备免受瞬时过压和静电放电的影响。
  • 封装: DO-214AC (SMA)
    • 小型封装,适合于空间有限的应用场景,提供高密度安装。

描述

SMAJ26CA 是一款双向 TVS 二极管,这意味着它可以在正向和反向两种偏置条件下提供保护。这种双向特性使其适用于需要在两种极性条件下都提供保护的应用场景。

应用场景

  1. 电子设备保护
    • 用于保护各种电子设备,如微控制器、传感器、通信设备等免受静电放电和瞬时浪涌电流的损害。
  2. 工业控制系统
    • 在工业控制系统中,用于保护电气设备免受电网波动或外界干扰带来的过压。
  3. 汽车电子
    • 在汽车电子系统中,用于保护电子控制单元(ECU)和其他敏感设备免受汽车电气系统中的瞬时过压。
  4. 通信设备
    • 用于保护通信设备中的敏感组件,确保在恶劣环境条件下也能稳定运行。

优势

  • 高峰值脉冲功率和电流
    • 能够在短时间内吸收和分散大量能量,提供强大的保护能力。
  • 宽工作温度范围
    • 适用于各种极端环境条件下的应用场景,从极寒到高温环境都能稳定运行。
  • 小型封装
    • DO-214AC 封装使其适合于空间有限的应用场景,提高了安装密度和灵活性。

安装注意事项

  • 在安装时,确保正确连接极性,以避免反向连接导致的损坏。
  • 选择合适的焊接方法,以确保良好的接触和可靠性。
  • 考虑到实际应用中的电气噪声和干扰,可能需要结合其他保护措施(如滤波器)来实现综合保护。

总结

SMAJ26CA 是一款高性能、双向 TVS 二极管,专为提供静电和浪涌保护而设计。其高峰值脉冲功率、宽工作温度范围和小型封装,使其成为各种电子设备保护的理想选择。通过正确安装和使用,这款设备可以有效地保护您的电子系统免受各种过载和干扰的影响。

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
