SMCJ54CA/TR13 产品概述 — Brightking(台湾君耀)

一、产品简介

SMCJ54CA/TR13 为 Brightking(台湾君耀)出品的双向 TVS(二极管瞬态抑制器),采用 SMC 表面贴装封装,专为保护直流/交流电源线及可逆极性电路免受雷击、开关瞬态或电缆耦合脉冲损害而设计。典型静态与冲击参数:反向截止电压(Vrwm)54V,击穿电压(Vbr)60V,钳位电压(Vc)87.1V(在指定峰值脉冲电流下),峰值脉冲电流 Ipp 17.3A,峰值脉冲功率 Ppp 1.5kW(基于 8/20µs 波形),反向漏电流 Ir 约 1µA(在 Vrwm 条件下)。

二、主要参数说明

  • 极性:双向,适用于极性可变或交流场合,正负极对称钳位。
  • Vrwm(工作反向耐压):54V —— 建议工作电压低于此值以避免持续击穿。
  • Vbr(击穿):60V —— 在小电流条件下开始进入雪崩区域。
  • 钳位电压 Vc:87.1V —— 在 Ipp(17.3A,8/20µs)脉冲下的瞬态极限电压。
  • Ipp 与 Ppp:Ipp=17.3A、Ppp=1.5kW,数值基于标准 8/20µs 冲击波形,用于衡量单次峰值冲击承受能力。
  • 漏电流 Ir:约 1µA,在常温与 Vrwm 处为典型值,随温度上升会增加。

三、典型应用

  • 48V/54V 直流配电系统、通信电源与供电站防护。
  • 工业控制、PLC、逆变器与电池管理系统中电源总线过压保护。
  • 需要双向保护的线路,如可逆电源接口、某些继电器或交流侧保护。
  • 对高能脉冲(雷击直击或近距感应)有较高耐受要求的场合。

四、设计与选型建议

  • 选型守则:工作电压(常态)应低于 Vrwm,并留有裕量(一般 10–20%);若常态接近 48V 或 54V,应考虑更高耐压或并联/备用保护。
  • 冲击能力评估:Ppp 与 Ipp 为 8/20µs 条件下的规格,若系统可能遭受不同波形或多次脉冲,应按能量累积和重复脉冲能力降额选型。
  • PCB 布局:靠近受保护端口或连接器安装,走线最短、最粗,利用热过孔或大铜面帮助散热;保持管脚与敏感器件间的距离并避免环路面积过大以减少感应。
  • 系统保护配合:与熔断器、PTC、限流电阻等配合使用,可避免超额瞬态或长时间过压导致器件过热损坏。
  • 漏电管理:在高阻抗或精密模拟电路中注意 Ir 造成的偏置影响,必要时增加隔离或滤波措施。

五、封装与可靠性注意

SMC 封装适合表面贴装大功率瞬态器件,机械强度与散热性能良好。双向结构无极性标识需求,但仍需注意焊接工艺(避免过热),并遵循厂家回流温度限制与储存防潮建议。长期可靠性会受重复冲击次数、脉冲能量和环境温度影响,建议在高温或多次冲击工况下参考厂方可靠性数据并适当降额使用。

总结:SMCJ54CA/TR13 为面向 48–54V 级别电源与可逆线路的高能量双向 TVS,具备 1.5kW(8/20µs)瞬态承受能力和较低漏电,适用于工业、通信与电源防护场景。选型与布局时应关注工作电压裕度、冲击波形与PCB散热设计,以保证长期可靠运行。

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
