SMCJ11CA/TR13 产品概述

一、产品简介

SMCJ11CA/TR13 是台湾 Brightking(君耀)推出的一款双向瞬态电压抑制器(TVS),采用 SMC(DO-214AB)封装。该器件为 11V 额定反向工作电压(VRWM=11V)双向保护型,适用于脉冲浪涌保护和瞬态冲击抑制。器件在极端环境下仍具有稳定的电气特性,工作温度范围为 -65℃ 至 +150℃,适合工业级及高应力电源/信号保护场合。

二、主要电气参数

  • 极性:双向(Bidirectional)
  • 额定反向截止电压 VRWM:11 V
  • 击穿电压 VBR(典型):12.2 V
  • 钳位电压 Vc(典型):18.2 V(对应峰值脉冲电流)
  • 峰值脉冲电流 Ipp:82.5 A
  • 峰值脉冲功率 Ppp:1.5 kW(按标准脉冲测试条件)
  • 反向静态电流 Ir(在 VRWM):1 µA(典型)
  • 工作温度:-65 ℃ ~ +150 ℃
  • 封装:SMC(DO-214AB)
  • 品牌/型号:Brightking(台湾君耀) SMCJ11CA/TR13
  • 备注:/TR13 表示卷带包装(Tape & Reel),便于贴片/自动化生产线使用

三、特性与工作机理说明

SMCJ11CA 为双向 TVS,意味着在正负极性瞬态过压时均能提供对称钳位保护,适合交流线路或可反向的直流系统。器件在电压超过 VBR(≈12.2V)时进入雪崩导通状态,将瞬态能量以钳位电压(≈18.2V)形式消散,从而限制后端电路受压。峰值脉冲电流 82.5A 与峰值脉冲功率 1.5kW 表示在短时大能量浪涌(如雷击诱发脉冲、开关突波)时具有较高的吸收能力。静态反向电流仅 1µA,确保在正常工作电压下对系统影响极小。

四、典型应用场景

  • 12V 车载电子(需注意是否满足汽车认证要求)与工业 12V 电源总线瞬态保护
  • 电源输入端的浪涌/雷击抑制
  • 交流低压信号线与双向数据线保护(差分线、RS-485、CAN 总线等)
  • 工业控制设备、电机驱动器的接入端浪涌防护
  • 通讯设备、变频器、电源模块等对瞬态过电压防护的外围保护元件

五、布板与使用建议

  • 放置位置:建议靠近需保护端口(接头、连接器或PCB入线处)布置,缩短到浪涌源的回流路径以降低寄生电感。
  • 散热与焊盘:SMC 封装具有较大散热面积,推荐遵循厂商推荐的焊盘/铜箔布局以利热散和可靠焊接,必要时增加底层散热铜并与热vias 联通。
  • 配合保护:对于超过器件额定能量的工况,应与熔断器、PTC 或串联限流电阻配合使用,以避免器件重复击穿或失效。
  • 多次脉冲能力:峰值参数为单次或标准脉冲测试结果,面对多次或更高能量冲击时应进行系统级验证并进行能量分担设计。
  • 温度影响:漏电流(Ir)随温度上升而增加,高温环境下应考虑漏电增加对系统静态功耗的影响和电路误动作风险。
  • 安装与回流:建议使用标准回流焊工艺,按制造商推荐的焊接温度曲线进行处理,避免长时间超温导致封装或内部结构损伤。

六、可靠性与选型注意

SMCJ11CA/TR13 适用于需要较大吸收能量和高温稳定性的场合。在选型时应确认:系统正常工作电压与 VRWM 的匹配(若系统为 12V 级,11V VRWM 为常见选择),器件钳位电压对于受保护元件的耐压是否安全,以及所面对的浪涌幅值与器件峰值吸收能力是否相匹配。若需符合特定行业认证(如车规 AEC-Q、UL 等),请向供应商索取相应证书与完整数据手册以做最终确认。

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
