SMBJ7.0CA/TR13 产品概述

一、产品简介

SMBJ7.0CA/TR13 为 Brightking(台湾君耀)出品的双向瞬态电压抑制器(TVS),采用 SMB(DO-214AA)封装。器件针对瞬态电涌、雷击和静电放电等过压瞬态提供高能量吸收能力,适用于保护电源线、通信接口和车载电子等对双向浪涌保护有要求的场合。

二、主要参数

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:7 V
  • 击穿电压(典型/或测试):7.78 V
  • 钳位电压(Ipp 条件):12 V
  • 峰值脉冲电流 Ipp:50 A
  • 峰值脉冲功率 Ppp:600 W
  • 反向电流 Ir:200 µA(在 Vrwm 条件下)
  • 类型:TVS(二极管)
  • 封装:SMB(DO-214AA)
  • 品牌:Brightking(台湾君耀)
  • 型号:SMBJ7.0CA/TR13

三、主要特点

  • 双向保护:对正、负瞬态均能有效钳位,适合交流或双向信号线保护。
  • 高能量吸收:600 W 峰值脉冲功率和 50 A 峰值脉冲电流,能承受较强的浪涌冲击。
  • 紧凑封装:SMB(DO-214AA)封装兼顾散热与占板面积,便于自动化贴装。
  • 低漏流:在标称工作电压下反向电流典型为 200 µA,有利于低功耗系统设计。

四、典型应用

  • 电源线路防护(7 V 左右的系统防浪涌)
  • 通信接口、数据线防护(双向信号)
  • 工业控制与电机驱动系统的浪涌抑制
  • 汽车电子(非车辆关键主线,以设计规范为准)
  • 家电与消费电子的瞬态过压保护

五、封装与可靠性

SMB(DO-214AA)封装便于散热和大电流通过,适用于自动贴装流程。建议在设计时预留热阻和足够的铜箔面积以提高浪涌能量耗散能力。器件应按厂家推荐的回流焊工艺进行焊接,避免超温和长时间加热导致封装应力或电气特性漂移。

六、选型与使用建议

  • 工作电压选择:选用 Vrwm 略高于设备正常工作电压但低于被保护器件最大耐压,以确保在正常工作下不触发保护。
  • 钳位判断:12 V 钳位电压应低于被保护侧可承受的最大瞬态电压。
  • 浪涌能力匹配:50 A 的峰值脉冲电流和 600 W 的功率指标为典型能力,具体能承受的能量与脉冲波形(宽度)相关,应参考厂方脉冲规范。
  • 布局建议:将 TVS 靠近被保护端口布局,最短走线到地或电源回路,尽量减小回路电感。

七、储存与可靠性注意

  • 储存环境应干燥、无腐蚀性气体,避免长时间潮湿高温。
  • 在焊接前若器件标示为潮湿敏感器件(MSL),请按回流工艺和烘烤要求处理。
  • 长期在极端温度或反复大浪涌环境下使用会影响寿命,应结合实际使用频次评估维护或更换周期。

八、采购与替代

型号末尾 “/TR13” 通常指带卷带包装或特定包装形式,便于 SMT 线直接上料。采购时请备注包装需求并向供应商确认规格书与浪涌测试曲线。如需不同钳位或单向器件,可在 Brightking SMBJ 系列中选择相邻 Vrwm 的型号以匹配系统需求。

如需我帮忙核对具体脉冲波形下的钳位曲线或给出替代型号建议,请提供系统工作电压与典型浪涌波形。

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
