SMCJ36CA(YANGJIE)产品概述

一、产品简介

SMCJ36CA 是扬杰(YANGJIE)出品的一款高能量瞬态抑制二极管(TVS),采用SMC(DO-214AB)封装,属于双向(Bi-directional)保护器件。该器件旨在对线路上的高能瞬态浪涌(如雷击、电源开关引起的电压尖峰等)提供快速、可靠的钳位保护,能在限定波形下吸收较大脉冲能量并将电压钳位在安全范围内,保护下游敏感元件不被峰值电压击穿。

二、主要参数(典型值)

  • 极性:双向
  • 反向截止电压 Vrwm:36 V
  • 击穿电压 Vbr:44.2 V
  • 钳位电压 Vc(在 Ipp 条件下):58.1 V
  • 峰值脉冲电流 Ipp(10/1000 μs):25.82 A
  • 峰值脉冲功率 Ppp(10/1000 μs):1.5 kW
  • 反向电流 Ir(在 Vrwm):5 μA
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:TVS(瞬态抑制二极管)
  • 封装:SMC(DO-214AB)
  • 品牌:YANGJIE(扬杰)

以上参数在典型测试条件下给出,具体特性请以厂商数据手册为准。

三、功能与优势

  • 双向保护:能同时抑制正、负方向的瞬态冲击,适合交流线路或可能出现反向脉冲的场合。
  • 高能量吸收能力:在10/1000 μs波形下可承受高达1.5 kW 的瞬态功率,使其能抵御较大能量的浪涌事件。
  • 有效钳位:在规定的冲击电流下将电压钳位在约58.1 V,有助于保护后端器件免受过电压损害。
  • 宽工作温度:-55 ℃ 至 +150 ℃,适应工业级及恶劣环境温度要求。
  • 低漏电流:在额定Vrwm下反向电流仅约5 μA,有利于降低系统静态功耗,尤其在待机或低功耗场景下优势明显。
  • 标准封装(SMC):便于与现有布局兼容,能够通过传统波峰/回流焊工艺装配,且散热面积较大,适合高能量器件。

四、典型应用场景

  • 工业电源与控制系统(如24 V/36 V 总线防护)
  • 通信设备的接口与线路防浪涌保护(基站、交换设备、光纤收发端等)
  • 电力监控、配电箱与逆变器外围保护
  • 电机驱动与伺服系统中对电源和信号线的瞬态防护
  • 其他需要对双向冲击进行抑制的场合,如感性负载开关产生的反向尖峰等

五、使用与注意事项

  • 非瞬态使用限制:TVS 用于吸收瞬态能量,不应用于持续承受高于 Vrwm 的电压,否则会导致器件发热、损坏或失效。
  • 布局建议:尽量靠近被保护端口或连接器布置,走线尽量短、宽以降低串联电感和电阻,推荐使用充足的铜皮面积和必要的散热孔/过孔。
  • 多次冲击与能量余量:在设计中考虑可能的多次浪涌事件,并留有足够裕量,避免器件在频繁或超额冲击后失效。
  • 温度与漏电:工作温度升高时漏电流会增加,应在热条件下评估系统总漏电并满足设计要求。
  • 焊接与可靠性:遵循厂商推荐的回流焊曲线和焊接工艺,避免超时或过温造成封装应力或内部损伤。

六、封装与热管理

SMC(DO-214AB)封装提供较大的焊盘接触面积和更好的热导通能力,便于将瞬态能量通过焊盘和PCB散热。为提升可靠性与长期性能,建议:

  • 在器件下方与周边配置较大铜面积作为散热梁;
  • 对于高频繁冲击场合,考虑在器件近旁增加热过孔将热量散至内层/底层铜箔;
  • 采用符合工艺的焊接曲线,避免焊接应力导致封装裂纹。

七、选型建议

  • 若被保护系统的最大工作电压接近或低于36 V,SMCJ36CA 是合适的选择;对于更高工作电压的系统,应选择更高 Vrwm 等级的TVS。
  • 在需双向保护或交流线路保护时,优先考虑双向型号;若仅需单向(例如严格直流正向保护),则单向型号能提供更低的钳位电压。
  • 在需要满足特定认证或汽车级应用时,请核实厂商的资格与相关认证数据。

总结:SMCJ36CA 是一款适用于中高能量瞬态抑制的双向 TVS 器件,凭借SMC封装与1.5 kW 的瞬态吸收能力,适合工业电源与通信等需要稳健浪涌防护的场景。最终设计选型建议结合实际系统电压、浪涌能量与频率,以及厂商完整数据手册进行确认。

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.
