SMAJ200A/TR13 产品概述

一、产品简介

SMAJ200A/TR13 为 Brightking(台湾君耀)生产的一款单向 TVS 二极管,封装为 SMA(DO-214AC)。该器件专为瞬态过电压和雷击/浪涌脉冲防护而设计,可在瞬态冲击发生时迅速钳位电压,保护后端电路免受损害。典型应用包括工业电源、开关电源前端、DC 总线保护及其它需对高电压瞬变进行抑制的场合。

二、主要电气参数

  • 类型:TVS,单向(极性)
  • 反向额定电压 Vrwm:200 V
  • 击穿电压 Vbr:224 V
  • 钳位电压 Vcl(峰值):324 V
  • 峰值脉冲电流 Ipp:1.2 A
  • 峰值脉冲功率 Ppp:400 W(峰值,具体测试条件见厂商数据表)
  • 反向电流 Ir:1 µA(在 Vrwm 条件下)

以上参数为器件典型性能指标,实际电气行为会随温度、脉冲波形和测试条件有所变化,设计时应参照完整数据手册。

三、特点与优势

  • 单向结构,反向截止性能稳定,适合直流系统防护;
  • 高钳位能力(324 V 峰值),在指定脉冲能量下能有效限制过电压幅度;
  • 低反向漏电流(1 µA),对正常工作状态影响小;
  • SMA 封装适合自动化贴装,体积小、散热与耐压性能平衡良好;
  • 品牌及质量可靠,适用于要求长期稳定性的工业应用。

四、应用场景

  • 工业 200 V 直流母线或中高压直流侧的浪涌保护;
  • 开关电源输入端、整流桥后端的过压防护;
  • 电机驱动、变频器辅助电路的瞬态抑制;
  • 工业控制器、逆变器、储能系统等对瞬态抗扰度有要求的设备。

设计时需确认被保护电路可承受钳位后的残压(324 V)及脉冲能量,若后端器件对残压敏感,应考虑级联保护或更高能量吸收能力的 TVS 器件。

五、封装与安装注意

  • 封装:SMA (DO-214AC),适用自动贴片与回流焊工艺;
  • 极性标识:单向 TVS 在封装上有阴极标识(带状),安装时须保证方向正确(阴极接保护地或电源负极);
  • 布局建议:尽量缩短 TVS 与被保护点之间的走线长度,减小回路电感;将接地端布置为低阻抗、大铜面积接地,以利于热量散逸与脉冲能量传导;
  • 焊接与回流:遵循厂家推荐的回流曲线,避免过热或骤冷导致封装性能退化。

六、选型与可靠性建议

  • 若工作电压接近 Vrwm,应留有裕量以避免长期偏压带来的寿命降低;
  • 对于频繁或高能量浪涌环境,考虑更高 Ipp 或更高 Ppp 级别的器件,或增加外部熔断/限流元件以分担能量;
  • 在苛刻环境下(高湿、高温或强振动),建议参考厂家的可靠性测试报告并进行必要的环境试验验证。

七、订购信息

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
