1.5SMC39CA/TR13 产品概述

一、产品简介

1.5SMC39CA/TR13 是台湾君耀(Brightking)出品的一款双向瞬态电压抑制器(TVS),采用 SMC (DO-214AB) 封装,专为中高电能浪涌及瞬态过压保护设计。器件在承受开关浪涌、雷击感应脉冲或大电流瞬态时,能够迅速钳位电压,保护下游元器件不被过压损坏,适用于工业电源、通信接口与车载电子等需双向保护的场景。

二、关键参数(核心规格)

  • 极性:双向
  • 反向截止电压 Vrwm:33.3 V
  • 击穿电压 Vbr:37.1 V
  • 钳位电压 Vc(Ipp):53.9 V(对应峰值脉冲电流 Ipp)
  • 峰值脉冲电流 Ipp:28.2 A
  • 峰值脉冲功率 Ppp:1.5 kW
  • 反向漏电流 Ir:1 μA(典型/最大,具体见厂家数据)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SMC (DO-214AB)
  • 类型:TVS(二极管)
  • 品牌:Brightking(台湾君耀)

三、主要特性与优势

  • 双向结构:对正负极性瞬态均能有效钳位,适合交流或可能反向瞬态的电路保护。
  • 高能量吸收能力:峰值脉冲功率 1.5 kW,能承受较强浪涌事件,配合合理系统设计,可大幅提升系统抗浪涌能力。
  • 低漏电流:工作时漏电小(Ir ≈ 1 μA),对待机功耗影响极小,适合对静态功耗敏感的应用。
  • 宽工作温度:-55~+150 ℃ 的工作温度范围,满足恶劣环境与工业级应用需求。
  • 标准封装:SMC 封装体积适中,易于手工/自动贴装与散热处理,便于工业化量产。

四、典型应用场景

  • 工业电源和控制系统(24V/36V 总线、工业以太网接口)
  • 通信设备(线路保护、功放供电保护)
  • 电动工具、楼宇自动化、能源设备等承受雷击/开关浪涌的场合
  • 车载电子(对双向瞬态有需求的系统模块,需结合车规认证与系统级设计)
  • UPS、逆变器及太阳能逆变系统的直流连接点保护

五、选型与设计建议

  • 选型原则:反向截止电压 Vrwm 应略高于电路最大工作电压,确保在正常工作条件不导通;1.5SMC39CA 的 Vrwm=33.3V 适配 24V 系统并能对 36V 瞬态提供保护,但在 36V 连续工作场合需谨慎评估。
  • 钳位与容错:钳位电压 53.9V(对应 Ipp 28.2A)决定了被保护器件在浪涌时可能承受的最大电压,设计时应确保下游元器件在该电压下不会损坏。
  • 热管理:SMC 封装在大能量吸收下会产生大量热量,建议靠近散热铜箔并使用充分的散热层/过孔,必要时在 PCB 上增加散热面或金属散热片。
  • 串联保护元件:对持续大电流或重复脉冲场合,建议在系统中配合熔断器、PTC 或限流电阻,以限制能量并防止器件损坏。
  • 布线与接地:将 TVS 尽量靠近受保护端口或连接器布局,缩短引线与走线长度以降低寄生电感;对地回路要粗短,必要时增设多个过孔以降低热阻和电阻。

六、可靠性与使用注意

  • TVS 为瞬态保护元件,不应作为频繁或长期承载电流的器件使用;在遇到连续异常工况(如短路)时,应有保护电路将其隔离或切断。
  • 参考厂商 Datasheet 的冲击波形和测试条件(Ppk、Ipp 对应的波形和脉冲宽度),以确保在指定测试条件下器件性能满足要求。
  • 焊接与回流:遵循 SMC 封装的通用焊接温度曲线及厂商建议,避免超温或长时间热负荷导致器件可靠性下降。
  • 环境与寿命:在高温高湿或化学腐蚀环境下,应考虑额外封装或保护措施以延长使用寿命。

七、总结

1.5SMC39CA/TR13 以其双向保护、高能量吸收与宽温度范围的特性,适合对中高能量瞬态事件有防护需求的工业与通信类系统。正确选型、良好的 PCB 布局与热管理、以及与熔断器等外围保护器件配合使用,能够发挥该器件的最佳保护效果,显著提高系统对突发过压与浪涌的耐受能力。若需更详细的测试曲线、典型钳位随电流变化图或推荐 PCB 尺寸,请参考 Brightking 官方 Datasheet 或联系我们获取完整技术资料。

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.
