SMBJ200A/TR13 产品概述
一、产品简介
SMBJ200A/TR13 是 Brightking（台湾君耀）出品的一款单向瞬态电压抑制二极管（TVS），采用 SMB（DO-214AA）表面贴装封装。器件专为对抗雷击、浪涌和瞬态过压事件设计，能够在短时高能脉冲下对被保护电路提供快速钳位，保护下游元件免遭损坏。
二、主要电气参数
- 极性：单向（Unidirectional）
- 反向截止电压 Vrwm：200 V
- 击穿电压 Vbr：224 V（典型/测试条件下）
- 钳位电压 Vc：324 V（在峰值脉冲电流下）
- 峰值脉冲电流 Ipp：1.9 A
- 峰值脉冲功率 Ppp：600 W（按行业脉冲测试条件）
- 反向电流 Ir：1 μA（在额定 Vrwm 下，常温）
这些参数表明 SMBJ200A 在高压直流或高压供电总线上具有良好的瞬态抑制能力，同时保持极低的静态泄漏电流。
三、封装与热管理
器件采用 SMB / DO-214AA 表面贴装封装，便于自动化贴装与批量生产。SMB 体型适中，既能承受较大脉冲能量，又便于在 PCB 上靠近受保护节点布局。为获得最佳散热与保护效果，建议在 PCB 上为器件留足铜箔面积并尽量缩短走线长度，必要时配合过孔扩散热量。
四、典型应用场景
- 工业电源与逆变器输入保护
- 开关电源（SMPS）和适配器的整流侧防护
- 通信和监控设备的电源总线保护
- 电机驱动、电磁兼容（EMC）防护电路
适用于需要在200V级别直流或脉冲过压场合提供瞬态抑制的场景。
五、安装与使用建议
- 将 TVS 器件尽量靠近被保护端口或连接器放置，以缩短吸收回路并降低感抗。
- 对于持续或重复出现的大幅浪涌，应评估器件热耗散能力并考虑串联限流元件或采用更高功率等级的保护方案。
- 典型钳位电压应低于被保护电路的最大可承受电压，以避免下游元件进入危险区。
六、可靠性与选型参考
SMBJ200A 以低漏电、快速响应和较高脉冲功率为特性，适合替换或升级同类中高电压保护器件。选型时应确认系统可能出现的最大冲击电流、允许的钳位电压以及长期工作温度对泄漏电流的影响，必要时与供应商确认具体测试曲线与可靠性数据。
七、订购信息
型号说明：SMBJ200A/TR13 — SMBJ200A 器件，/TR13 通常表示卷带盘装（便于贴片机自动化生产）。如需样品、完整规格书或可靠性测试报告，请联系 Brightking 或其授权分销商获取详细资料。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
