SMBJ6.5CA(GOODWORK)产品概述

一、概述

SMBJ6.5CA 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),封装为 DO-214AA(SMB),专用于抑制静电放电(ESD)和浪涌冲击。其典型工作场景包括电源线、数据接口、通信端口以及工业/汽车电子进线的浪涌保护,尤其适合需要双向对称钳位的交流或可极性线路。

二、主要参数(典型值)

  • 极性:双向
  • 反向截止电压 Vrwm:6.5 V
  • 击穿电压(典型):7.22 V
  • 钳位电压 Vc(在峰值脉冲电流下):11.2 V
  • 峰值脉冲电流 Ipp:53.6 A
  • 峰值脉冲功率 Ppp:600 W(标准脉冲条件下)
  • 反向漏电流 Ir:500 μA(在 Vrwm 条件下)
  • 工作结温度范围:-55 ℃ ~ +150 ℃(Tj)
  • 封装:DO-214AA(SMB)

三、性能特点

  • 高能量吸收能力:600 W 峰值脉冲功率,能够承受瞬态浪涌和雷击诱发的能量输入。
  • 低钳位电压:在大电流冲击下仍能将电压钳位在约 11.2 V,保护后端电路免受过压破坏。
  • 双向保护:适合交流或极性不确定的应用场景,无需关心安装方向。
  • 宽温度范围:-55 ℃ 至 +150 ℃ 的结温范围,适用于严苛工业和汽车环境。
  • SMB 封装:表面贴装,热散能力与机械强度适中,便于自动化贴装和回流焊接。

四、典型应用

  • 通信基站、网关和路由器的电源/接口保护
  • 汽车电子(车载CAN/LIN 总线、车身电子防护)
  • 工业控制设备、变频器和电机驱动器的浪涌入口处
  • 消费电子的电源输入和数据接口(USB、HDMI 等需要双向保护的线缆)
  • 仪器仪表与电力监控系统

五、布板与安装建议

  • 尽量将 TVS 放置在受保护线缆或器件的入口处,靠近连接器或线缆焊盘,最小化寄生电感和走线长度。
  • SMB 封装为 SMD,采用标准回流焊工艺,建议遵循厂商提供的回流温度曲线及湿敏等级(MSL)要求。
  • 高能量冲击时会产生热量,若频繁承受大浪涌,建议在 PCB 设计时考虑散热铜箔和通孔散热路径。
  • 双向器件无极性标识要求,但实际封装上可能有标记,请参照产品数据手册确认。

六、选型要点

  • 工作电压匹配:选择 Vrwm 稍高于电路正常工作电压的型号,SMBJ6.5CA 适用于约 6.5 V 等级的直流/交流线路。
  • 钳位能力:根据被保护器件的耐压能力,确认 11.2 V 的钳位电压是否足以保护后级电路。
  • 能量需求:对于可能遭受高能雷击或长脉冲浪涌的场合,确认 600 W 的峰值能力与实际浪涌波形(例如 10/1000 μs)是否匹配。
  • 环境适应性:在高温/汽车环境中使用时,确认结温范围和可靠性测试数据。

七、可靠性与注意事项

  • 虽具备高能量吸收能力,但在多次大电流冲击后器件性能可能退化,建议在关键系统中考虑冗余或定期检查。
  • 安装时避免过度机械应力,焊接后如有显著变形应重新评估。
  • 详细电气特性、测试条件和包装信息应参考 GOODWORK 正式数据手册或向供应商索取样品与应用资料。

八、总结

SMBJ6.5CA 是一款面向工业和汽车级应用的双向 SMB TVS 器件,具有较低的钳位电压、较高的峰值吸收能力和宽温度适应性,适合用于需要对称保护且工作电压在 6.5 V 级别的场合。选型时应综合考虑工作电压、钳位要求和实际浪涌能量谱,并严格按照厂商建议进行 PCB 布局与焊接工艺控制。若需更详细的电气曲线、波形响应或认证信息,可联系厂商获取完整数据手册。

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.

Replenishment inquiry Typical RFQ workflow
