SMBJ100CA/TR13 产品概述

一、产品简介

SMBJ100CA/TR13 是台湾君耀(Brightking)推出的一款双向瞬态电压抑制器(TVS)二极管,采用 SMB(DO-214AA)封装,专为抑制瞬态过电压和浪涌脉冲设计。该器件在结构上为双向钳位型,能够在正、负两极性瞬态事件中提供对称保护,适用于中高电压等级的电源及信号线防护场合。

主要电气参数(典型/标称):

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:100 V
  • 击穿电压(Bv):111 V
  • 钳位电压(Vcl):162 V(峰值脉冲时)
  • 峰值脉冲电流 Ipp:3.7 A
  • 峰值脉冲功率 Ppp:600 W(8/20μs 浪涌波形)
  • 反向电流 Ir:1 μA(在指定电压下的典型泄漏)

型号后缀说明:TR13 通常表示卷带包装(Tape & Reel),便于表面贴装(SMT)自动化贴装与批量生产。

二、主要特性与优势

  1. 高浪涌吸收能力:600 W 的峰值脉冲功率能有效吸收工业环境和雷击感应所产生的短时高能量浪涌,降低后端电路受损风险。
  2. 双向对称保护:可同时抑制正向和反向的瞬态电压,适用于交流电源、差分信号线或没有明确极性的线路。
  3. 低泄漏电流:典型反向电流仅约 1 μA,有利于减少待机功耗和维持系统静态性能。
  4. SMB 封装:DO-214AA 提供较好的热耗散能力与机械强度,便于高速贴装与可靠焊接。
  5. 品牌与可获性:Brightking(台湾君耀)具有成熟的器件设计与制造经验,适合要求批量可靠性的工业应用。

三、典型应用场景

  • 工业电源和控制系统的输入/输出端防护,尤其是 48 V/60 V 及更高电压等级的设备。
  • 通信电源、基站设备与交换设备中对电源轨和信号线的浪涌抑制。
  • 开关电源、逆变器与驱动电路的输入侧瞬态保护。
  • 电动工具、仪器仪表及外围模块的稳健防护设计。
  • 各类需要双向保护的线路,如交流供电线、数据对地无明确极性的接口通道等。

四、封装与装配建议

  • 封装形式:SMB(DO-214AA),适配标准 SMB PCB 尺寸与焊盘布局,利于自动化贴装。
  • 焊接工艺:推荐采用回流焊工艺;注意控制峰值回流温度和保温时间以避免器件热应力。
  • 散热考虑:尽管 SMB 封装具有一定热能力,长时间高能量浪涌可能导致热累积,建议在布局时预留散热路径并避免紧密堆叠敏感器件。
  • 储存与搬运:按常规半导体元件防潮、静电防护措施存放与运输,贴片卷盘适合 SMT 线直接上料。

五、使用注意事项

  • 安装位置:典型为被保护线路与共同参考(地或负极)之间,双向器件可直接并联在被保护点上。
  • 选型匹配:钳位电压 162 V(峰值)应低于后端器件能承受的最大电压;同时 Vrwm=100 V 需匹配被保护电路的工作电压等级。
  • 浪涌能量能力:Ppp=600 W(通常按 8/20 μs 波形测定)表明单次浪涌能力,连续或高频次冲击会缩短器件寿命或损坏器件,应结合熔丝或限流元件联合保护。
  • 温度与可靠性:器件参数会随环境温度变化,长期在极限条件下工作可能影响泄漏、电压参数与寿命。

六、典型电路接法示例

  • 双向 TVS 用于两线制电源或信号线时,直接并联于两线之间;在电源输入端,可并联于正负极或正极与地之间实现对称钳位。
  • 为防止大电流冲击进入系统,常与快速熔断器、PTC 自恢复保险或串联电感/限流电阻搭配使用,以提高整体保护可靠性。

七、订购信息与建议

  • 建议型号:SMBJ100CA/TR13(Brightking,SMB 封装,卷带包装)
  • 在选型时,请确认系统的最大持续工作电压不超过 Vrwm(100 V),并确保钳位电压(162 V)不会对下游器件造成损害。
  • 如需更详细的浪涌测试条件、温度特性曲线或封装外形尺寸,请参考制造商完整数据手册或联系 Brightking 授权代理商获取官方技术支持。

如需替代型号推荐、PCB 焊盘参考图或在特定应用(例如48 V 通信电源、工控设备)中的保护设计建议,我可以根据具体场景提供更详细的布局与保护电路方案。

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
