SMCJ36A/TR13 产品概述

一、产品定位与核心参数

SMCJ36A/TR13 为 Brightking(台湾君耀)出品的一款单向瞬态电压抑制二极管(TVS),采用 SMC(DO-214AB)封装,专为抑制瞬态过压脉冲与浪涌能量设计。主要电气参数如下:

  • 反向工作电压 Vrwm:36 V
  • 击穿电压 Vbr(典型):40 V
  • 钳位电压 Vc:58.1 V(在峰值脉冲电流 Ipp 条件下)
  • 峰值脉冲电流 Ipp:25.9 A
  • 峰值脉冲功率 Ppp:1.5 kW(典型标准脉冲测试条件下,例如 10/1000 μs 波形)
  • 反向泄漏电流 Ir:1 μA(在 Vrwm 条件下)
  • 工作温度范围:-65 ℃ ~ +150 ℃

二、主要特性与优势

  • 高能量吸收能力:1.5 kW 峰值脉冲功率,能有效吸收系统中的浪涌和雷击诱发瞬态能量。
  • 精确钳位:58.1 V 的钳位电压(对应 25.9 A 峰值电流),在抑制瞬态电压的同时减小对下游器件的应力。
  • 低反向泄漏:典型 1 μA 的反向电流,有利于低功耗与高阻抗电路的稳定性。
  • 宽温度范围:-65 ℃ ~ +150 ℃,适用于工业级及高温环境应用。
  • 标准封装:SMC(DO-214AB)便于波峰/回流焊接及自动贴片生产,热耗散能力良好。

三、典型应用场景

  • 工业电源与配电保护(24 V 或 36 V 直流回路的浪涌保护)
  • 通信设备的线路保护(防止雷击与开关瞬变)
  • 电机驱动与继电器控制电路的瞬态抑制
  • 工业控制器、PLC、变频器等对抗电磁冲击的场合

四、选型与注意事项

  • Vrwm 的选择应大于或等于最大正常工作电压,但留有安全裕量;SMCJ36A 的 36 V 适用于 24 V 系统及部分 36 V 直流总线保护。
  • 钳位电压需与被保护器件的耐压匹配,确保钳位后的电压不会超过下游元件允许值。
  • 对于重复或长期出现的浪涌,应考虑热管理与并联/级联配置以分散能量。
  • 在高温环境下应适当降额使用,参考厂商的湿热与功率降额曲线(如需长期高功率吸收,应咨询供应商数据)。

五、封装与装配建议

  • SMC(DO-214AB)封装要求标准 PCB 足迹,推荐在器件引脚处增加铜箔以提高散热能力。
  • 推荐采用回流焊或波峰焊工艺,遵循无铅或有铅的焊接温度曲线,避免过热导致器件性能退化。
  • TR13 中的 “TR” 表示卷带(Tape & Reel)包装,便于自动贴装;“13” 通常指 13 英寸卷盘规格,适合批量 SMT 生产线。

六、可靠性与测试建议

  • 出厂前应进行浪涌测试与静态电参数测试以保证一致性。
  • 在关键应用中建议进行系统级冲击/浪涌试验,验证在实际接地与布线条件下的保护效果。
  • 若用于汽车或特殊行业,需确认是否具备相应的行业认证(如 AEC-Q100 等)。

总结:SMCJ36A/TR13 提供较高的峰值吸收能力、明确的钳位性能和工业级温度适应性,是面向 24 V~36 V 等中高电压直流系统中可靠的浪涌保护元件。针对具体应用的浪涌波形、重复率和热管理方案,建议结合系统设计进行验证或咨询 Brightking 技术支持。

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
