SMBJ5.0CA 产品概述

一、产品简介

SMBJ5.0CA 是扬杰(YANGJIE)生产的一款双向瞬态电压抑制器(TVS),封装为SMB(DO-214AA)。器件专为抑制瞬态过电压和浪涌能量设计,适用于直流/交流信号线及电源总线上对高能脉冲的保护需求,尤其适合5V额定系统的浪涌防护应用。

二、主要技术参数

  • 类型:TVS,双向(Bidirectional)
  • 反向截止电压 Vrwm:5V
  • 击穿电压 Vbr:7.07V(典型)
  • 钳位电压 Vc:9.2V(在峰值脉冲条件下)
  • 峰值脉冲电流 Ipp:65.2A(10/1000µs 波形)
  • 峰值脉冲功率 Ppp:600W(10/1000µs 波形)
  • 反向电流 Ir:≤800µA(在 Vrwm 条件下)
  • 工作温度:-55℃ ~ +150℃
  • 封装:SMB(DO-214AA)
  • 品牌:YANGJIE(扬杰)

三、主要特性与优势

  • 双向结构可对称抑制正、负极性瞬态脉冲,适用于无极性或交流环境中保护设备;
  • 高脉冲吸收能力(600W@10/1000µs)可应对工业级或现场的雷击/开关瞬变能量;
  • SMB 封装具备良好散热与机械强度,便于表贴安装并适配常见电路板布局;
  • 宽工作温度范围,适应恶劣环境与工业级应用要求;
  • 对于5V额定系统,反向截止电压匹配,可在正常工作条件下保持低导通,避免误触发。

四、典型应用场景

  • USB、供电总线、通信接口(如RS-485、CAN)等5V或近5V系统的浪涌保护;
  • 工业控制设备、嵌入式电源模块、楼宇自动化中的端口保护;
  • 电源输入端、接口板、终端设备的浪涌与静电放电防护;
  • 需要双向防护的信号线和差分线应用场合。

五、封装与安装建议

  • SMB(DO-214AA)表贴封装,推荐靠近被保护端口或连接器放置,以减小走线和回路电感;
  • 布局时应尽量缩短器件两端导线长度,使用宽铜箔和大量过孔以利于热量扩散;
  • 焊接遵循常规回流焊工艺及厂商焊接指南,避免长时间高温重流以保护内部结构。

六、使用注意事项

  • 峰值功率与电流是基于10/1000µs脉冲波形的瞬态性能,非连续或长期功耗能力有限,不能作为稳态电压钳位器长期工作;
  • 反向电流 Ir 相对较大,若用于低功耗或高精度电路需评估漏电容忍度;
  • 在特定系统(如汽车电子)应用前,建议结合系统级标准(例:IEC 61000-4-5)进行整机验证。

七、可靠性与选型建议

  • 选择时确认系统最大可能浪涌能量与器件 Ppp、Ipp 能否匹配,必要时并联或级联保护器件以提高能量吸收能力;
  • 若保护对象为单向直流电源,应优先考虑单向型 TVS;若为双极性信号线或不确定极性场合,SMBJ5.0CA 的双向特性更合适;
  • 对于对漏电极其敏感的设计,可选取漏电更低或更高 Vrwm 余量的型号。

本产品适合需要在5V级别实现高能脉冲抑制且对双向保护有要求的工业与消费类电子设备。具体电气特性与焊接工艺请参照扬杰提供的完整规格书与应用说明。

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
