SMAJ60CA/TR13 产品概述

SMAJ60CA/TR13 是 Brightking(台湾君耀)推出的一款双向瞬态电压抑制(TVS)二极管,封装为 SMA(DO-214AC)。该器件专为保护中高压直流/交流电路免受瞬态过压(如雷击、开关突变、感性负载释放等)冲击而设计,具有响应快、钳位电压低、工作温度范围宽等特点,适用于工业电源、通信接口、电源模块和其他需要对双向浪涌保护的场合。

一、主要电气参数与规格概览

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm(稳压电压 / 最大工作电压):60 V
  • 击穿电压 Vbr:66.7 V(典型)
  • 钳位电压 Vc:96.8 V(在指定脉冲条件下测得)
  • 峰值脉冲电流 Ipp:4.1 A
  • 峰值脉冲功率 Ppp:400 W(典型测试条件)
  • 反向漏电流 Ir:1 μA(在 Vrwm 测试条件下典型值)
  • 工作温度范围:-65 °C ~ +150 °C
  • 类型:TVS 二极管(瞬态电压抑制器)
  • 封装:SMA(DO-214AC,表面贴装)
  • 包装形式:/TR13 表示卷盘包装(Tape & Reel),便于自动化贴片生产

二、产品特点与优势

  • 双向保护:可对正负方向的瞬态过压进行对称限幅,适合交流线路或双向脉冲环境。
  • 高功率吸收能力:在规定脉冲条件下能够承受高达 400 W 的瞬态能量,配合 4.1 A 峰值脉冲电流,能有效钳制高能突发浪涌。
  • 低漏电:典型反向漏电流仅 1 μA,有利于在不增加静态功耗的场合长期并联使用。
  • 宽温度范围:工作温度覆盖 -65 °C 至 +150 °C,适应工业级及恶劣环境应用。
  • SMA 封装:体积小、散热及焊接可靠,适合表面贴装工艺与自动化生产。

三、典型应用场景

  • 工业电源与驱动模块的输入端过压保护
  • 通信设备、串行/并行接口、差分线对的浪涌保护(交流/双向脉冲)
  • 电池管理系统(BMS)和逆变器的瞬态保护
  • 继电器、电磁阀等感性负载驱动侧的浪涌抑制
  • 车载电子(在符合车辆工作温度及 EMC 要求的前提下)以及工业控制设备

四、封装与安装建议

  • 封装为 SMA(DO-214AC),适用于标准 SMT 贴片线。/TR13 表示采用卷盘包装,便于贴片机取料。
  • 布局建议:将 TVS 器件尽量靠近被保护的引脚或器件,并保证到接地点(地平面或负极)的走线最短、低电感;使用宽铜带提升瞬态电流承载能力与散热。
  • 焊接建议:采用符合 J-STD-020 的回流焊工艺,对铅无铅工艺需控制峰值温度与保温时间,避免超出元件热极限。
  • 底板散热:在可能的条件下配合较大铜面积或散热垫,以改善器件的热耗散能力,延长浪涌多次事件下的可靠性。

五、使用注意事项

  • 钳位电压与脉冲条件相关:所给的钳位电压(96.8 V)与峰值脉冲功率/电流在规定测试条件下相关,实际钳位电压会随着能量波形和源阻抗变化而改变,设计时应留有余量。
  • 额定 Vrwm 为最大持续工作电压,长期工作电压不应超过此值,否则会增加漏电或导致器件早期击穿。
  • 对于高频或高速信号线保护,应评估 TVS 对信号完整性的影响(电容、反向恢复特性等),必要时选择专用的低容或低电容 TVS 器件。
  • 多次大能量脉冲后器件可能退化,应在可靠性设计中考虑冗余或定期检测替换策略。

六、选型与替代参考

  • 若系统工作电压低于 60 V 的稳态场合,SMAJ60CA 提供合适的稳态保护平台;若需要更低钳位或更高能量吸收,应选择型号参数更高或功率等级更大的 TVS。
  • 对于单向保护场合,请选择对应的单向(Unidirectional)TVS 型号以获得更低的反向漏电与更明确的极性保护。
  • 若空间或功率需求不同,可考虑同系列的 DO-214AA(SMB)或更大功率的封装以满足更高的脉冲能力。

七、结论

SMAJ60CA/TR13 是一款针对中高压双向瞬态保护优化的 TVS 二极管,具备 60 V 稳态耐压、约 66.7 V 的击穿电压及典型 96.8 V 的钳位电压,配合 4.1 A 峰值脉冲电流与 400 W 峰值脉冲功率(典型测试条件),在工业、通讯与电源保护场合中能够提供可靠的浪涌防护。使用时应关注封装散热、布线最短化及钳位余量,以确保长期稳定运行。如需满足特殊波形或更高可靠性要求,可与供应商讨论更详细的测试条件与应用验证。

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.
