产品概述：SMAJ15A 保护二极管

一、基本信息

  • 品牌：BORN（伯恩半导体）
  • 封装：SMA（DO-214AC）
  • 产品类型：瞬态抑制二极管（TVS Diode）

二、产品特性

SMAJ15A是一款高性能的瞬态电压抑制二极管，专为保护敏感电子设备免受瞬态电压冲击而设计。它适用于各种应用，包括电源线保护、USB接口保护、通信线路防护及各种工业设备的过电压保护。

三、关键参数

  1. 反向击穿电压（VBR）：SMAJ15A的典型反向击穿电压为15V。这使得它能够有效地抑制来自电路内部和外部的瞬态电压，防止这些异常电压对电子器件造成损害。

  2. 最大功耗（PM）：该器件的最大功耗为400W（在转瞬间），这使得SMAJ15A可以吸收高能量的瞬态脉冲，而不会发生击穿或被损坏。

  3. 放电电流（IFSM）：其最大放电电流可达到100A，更加增强了对电流过载的承受能力。

  4. 工作温度范围：-55°C至+150°C，广泛适用于各种环境条件。

  5. 封装类型：SMA（DO-214AC）封装，体积小巧，易于布局和散热，便于贴片安装。

  6. 响应速度：SMAJ15A具有快速响应特性，能够在极短的时间内反应过电压事件，有效保护后续电路组件。

四、应用场景

  1. 电子设备保护：适用于计算机、电视、音响系统、消费电子产品等设备中，以防止静电放电（ESD）和雷电过电压对元器件的损害。

  2. 工业应用：可以用于制造设备、传感器驱动电路和机器人控制器等，确保其在高电压条件下正常运行且不受破坏。

  3. 通信线路：在各种通信设备的输入端提供保护，确保信息传输安全稳定，避免由于瞬态电压引发的数据丢失或设备损坏。

  4. 电源线保护：内置于电源适配器和变压器中，防止电源波动对连接设备造成的影响。

五、设计与兼容性

SMAJ15A在设计上兼容现有的电子设计标准，可以与多种其他保护元件一起使用，形成有效的电路保护方案。使用此组件时，设计工程师应根据具体电路的特性进行合理选择，以确保最佳的保护效果。

六、总结

SMAJ15A作为BORN（伯恩半导体）推出的一款关键瞬态电压抑制二极管，凭借其优越的性能指标和广泛的应用前景，已经成为电子元器件市场中不可或缺的一部分。无论是在日常消费电子，还是在专业的工业自动化设备中，SMAJ15A都能够提供必要的保护措施，保障电路的安全与稳定，是设计和维护高性能电路系统的重要选择。

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
