5.0SMDJ75A/TR13 产品概述

一、产品简介

Brightking(台湾君耀)5.0SMDJ75A/TR13 为单向 TVS(二极管瞬态电压抑制器),采用 SMC(DO-214AB)贴片封装,专为瞬态浪涌与静电放电(ESD、Surge)保护设计。器件在正常工作电压下漏电小、在瞬态事件时能迅速钳位,保护下游电路免受高能量脉冲损坏。

二、主要电气参数

  • 极性:单向(Unidirectional)
  • 反向截止电压 Vrwm:75 V
  • 击穿电压(Vbr):83.3 V
  • 钳位电压(Ipp 条件下):121 V
  • 峰值脉冲电流 Ipp:41.4 A
  • 峰值脉冲功率 Ppp:5 kW(按行业常用脉冲条件测量)
  • 反向漏电流 Ir:2 µA(在 Vrwm 条件下)
  • 类型:TVS (瞬态电压抑制器)
  • 封装:SMC(DO-214AB)
    这些参数表明该型号在大能量浪涌事件中具有较强的能量吸收能力和较低的静态漏电,适合中高电压保护场合。

三、产品特点

  • 高峰值脉冲功率(5 kW),对短时大能量浪涌有良好吸收能力;
  • 低钳位电压(121 V @ Ipp),在脉冲发生时能有效限制系统电压上升;
  • 低漏电流(2 µA),适合对静态功耗敏感的线路;
  • SMC 封装便于自动化贴装与焊接,同时具备较好的热耗散能力;
  • 单向结构适合直流电源或单极性信号线保护。

四、典型应用场景

  • 通信设备、基站电源保护(48 V 总线或类似中高压直流系统);
  • 工业电源与控制器保护;
  • 电源入口与配电模块的浪涌抑制;
  • 串联/并联敏感元件(DC/DC、驱动电路)前的过压保护;
  • 需要高能量吸收且对反向漏电有严格要求的场合。

五、封装与安装注意事项

  • SMC(DO-214AB)为表面贴装大功率封装,推荐短、宽的接地与电源走线以降低回路电感;
  • 为承载脉冲能量,建议使用充分的铜箔面积与散热通孔(vias)以利热量扩散;
  • 布线时尽量将 TVS 靠近被保护端口或器件放置,最短化连接路径;
  • 在高重复脉冲或持续高能事件下,应考虑器件的热回流与功率平均化(避免连续超载运行)。

六、选型与使用建议

  • 若系统工作电压接近或低于 48 V,选择 Vrwm=75 V 可提供合适余量;
  • 设计时核对系统允许的最大钳位电压(121 V)是否不会损伤下游器件;
  • 注意峰值脉冲 Ipp 与 Ppp 是短时能力指标,不等同于连续功率能力,应避免长期在高脉冲环境中持续工作;
  • 如需更高能量或双向保护,可考虑相应型号或并联/串联方案,并与供应商确认脉冲测量条件。

七、包装与订购信息

型号:5.0SMDJ75A/TR13,品牌:Brightking(台湾君耀),封装:SMC(DO-214AB)。批量采购或样品咨询请参考厂商规格表与出货条款,确认包装带宽、卷带盒(TR)等信息以匹配贴片生产线需求。

如需完整数据手册、脉冲测试波形条件或在具体电路中的钳位特性曲线,可向供应商索取完整 Datasheet,以便进行详细的热设计与可靠性评估。

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
