SMAJ10CA-AT/TR13 产品概述

一、产品简介

SMAJ10CA-AT/TR13 是 Brightking(台湾君耀)推出的双向瞬态抑制二极管(TVS),采用 SMA(DO-214AC)表面贴装封装,专为保护电子系统免受瞬态过电压冲击而设计。器件具有低轮廓、低电感和玻璃钝化结结构,适合在空间受限且对瞬态响应要求高的应用场景使用。该型号在 10/1000μs 波形条件下可提供高达 400W 的峰值脉冲功率能力,重复率(占空比)为 0.01%。

二、主要电气参数

  • 极性:双向(Bidirectional),可同时抑制正向和反向瞬态电压
  • 反向截止电压(Vrwm):10 V
  • 击穿电压(VBR):11.1 V(典型/规格书测试条件)
  • 钳位电压(Vclamp):17 V(于 10/1000μs 波形及峰值脉冲电流条件下)
  • 峰值脉冲电流(Ipp):23.5 A
  • 峰值脉冲功率(Ppp):400 W(10/1000μs,重复率 0.01%)
  • 反向漏电流(Ir):5 μA(在 Vrwm 条件下的典型值)
  • 工作温度范围:-55 ℃ 至 +150 ℃

三、结构与封装特点

  • 封装类型:SMA(DO-214AC),表面贴装(SMD),占板面积小、适合集成化设计
  • 封装特性:低轮廓、低电感,有利于快速响应高频瞬态脉冲
  • 结工艺:玻璃钝化结,提高器件长期稳定性与耐湿性能
  • 标准化卷带包装(TR)便于自动贴装与量产流程集成

四、典型性能与优点

  • 优秀的钳位能力:在指定冲击条件下能将过电压钳制在安全范围(典型钳位电压 17V),有效保护后端敏感器件
  • 高能量吸收:400W 峰值功率(10/1000μs)适合对抗雷击、浪涌和电源瞬变等大型能量冲击
  • 低电感与快速响应:适用于 I/O 接口、高速信号线及开关电源输入等对瞬态响应速度有要求的场景
  • 双向保护:无需额外方向判断,适合直流或交流两端抑制应用

五、典型应用场景

  • I/O 接口保护:串口、USB、串并行总线以及各种信号线防护
  • AC / DC 电源浪涌保护:电源输入端的浪涌吸收与过压钳制
  • 通信设备、消费类电子、工业控制设备中的外部接口与电源口保护
  • 任何需要抑制高能量、低频脉冲(如雷电感应、开关瞬变)的场景

六、选型与设计注意事项

  • 额定电压匹配:选择 Vrwm(10V)应高于系统正常工作电压,留有适当裕量以避免长期应力造成漏电或误动作
  • 钳位电压考虑:钳位电压(17V)为器件在峰值冲击时的典型值,系统中被保护器件应能承受该电压或应配合其他限压元件
  • 峰值能力限制:Ppp 与 Ipp 为短时冲击能力,重复冲击或长脉冲需注意热累积与器件寿命
  • 布线与热管理:在 PCB 布局时应尽量缩短器件与需保护节点之间的走线,确保低阻抗回路;必要时考虑散热路径与铜箔面积以降低温升
  • 并联与分流:并联使用需谨慎,最好在同一版图与相近热环境下并联,并注意均流问题

七、可靠性与存储

  • 工作温度范围宽(-55 ℃ 至 +150 ℃),适应严苛环境
  • 采用玻璃钝化结与封装工艺以提升长期稳定性
  • 存储与焊接:建议遵循厂家提供的存储、潮湿敏感等级(MSL)和回流焊温度曲线,以防封装或性能劣化

八、封装与生产集成建议

  • 封装:SMA(DO-214AC),适用于自动贴装与后续回流焊工艺
  • 推荐 PCB 布局要点:靠近需保护端口放置、走线短且宽、避免形成环路,提高保护效果并降低对地/电源的寄生感应
  • 生产:采取标准卷带供料(TR),便于贴片机送料与批量装配

总结:SMAJ10CA-AT/TR13 是一款适合表面贴装、面向 I/O 接口与电源浪涌保护的高能 TVS 器件,具有低电感、低封装轮廓与可靠的钳位能力。在选择与集成时注意电压匹配、热管理与 PCB 布局,可在多种商业与工业应用中提供稳健的瞬态过压保护。若需更详细的测试条件、曲线图或封装尺寸,请参考 Brightking 官方规格书或联系供应商获取数据手册。

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.
