SMCJ150CA/TR13(Brightking 台湾君耀)SMC 封装 双向 TVS 二极管 — 产品概述

一、产品概述

SMCJ150CA/TR13 是台湾君耀(Brightking)推出的双向瞬态电压抑制器(TVS),采用 SMC(DO-214AB)封装,专为抑制瞬态浪涌和雷击脉冲设计。器件在双向工作模式下可同时对正负极性瞬变进行钳位保护,适合中高电压系统的浪涌防护需求。

二、主要电气参数

  • 极性:双向
  • 反向额定工作电压 Vrwm:150 V(持续工作时的最大直流电压)
  • 击穿电压 Vbr:约 167 V(典型)
  • 钳位电压 Vc:约 243 V(在峰值脉冲电流 Ipp 条件下)
  • 峰值脉冲电流 Ipp:6.2 A
  • 峰值脉冲功率 Ppp:1.5 kW(标准脉冲测试条件下的瞬态吸收能力)
  • 反向漏电流 Ir:约 1 µA(在 Vrwm 下)
  • 工作温度范围:-65 ℃ 到 +150 ℃

三、主要特点与优势

  • 双向结构:可对双极性浪涌同时抑制,省去极性判断与额外器件。
  • 高能量吸收:1.5 kW 峰值瞬态功率与 6.2 A 峰值脉冲电流,适合承受中等能量浪涌。
  • 低漏电流:典型 1 µA,有利于高阻抗电路和低功耗系统。
  • 宽温度范围:-65 ℃ 至 +150 ℃,适应工业级环境。
  • SMC 封装:热容量大、可靠性高,适合 PCB 表面贴装与散热设计。

四、典型应用场景

  • 工业电源与逆变器端口的浪涌保护
  • 通信与网络设备的传输线防护
  • 配电与电力电子设备的输入端过压抑制
  • 测试测量仪器、控制器与弱电系统的瞬态防护
    (注:若用于汽车电子需确认器件是否满足 AEC-Q 等级要求)

五、封装、布局与可靠性建议

  • 封装:SMC(DO-214AB)提供较好的热散能力与机械强度。
  • PCB 布局:尽量将 TVS 靠近被保护端口或连接点放置,缩短引线/铜迹以降低寄生电感。采用较宽的铜箔和必要的热铜区以帮助散热。
  • 热设计:在需承受多次或高能量浪涌的应用中,设计足够的散热面积与热过孔,必要时配合熔断器或串联阻抗限制浪涌能量。
  • 焊接可靠性:遵循厂家回流焊温度曲线,避免过高温度和长时间高温退化封装材料。

六、选型与使用注意事项

  • 工作电压裕量:Vrwm(150 V)应高于系统最大正常工作电压并留有一定裕量,避免在接近 Vrwm 情况下长期工作。
  • 钳位电压匹配:钳位电压(约 243 V)必须低于系统能承受的最大瞬态电压,确保下游元件安全。
  • 能量管理:Ppp 与 Ipp 能力有限,频繁或高能量浪涌需通过并联/更大功率器件或外加限流元件(熔丝、电阻)来分担。
  • 环境与老化:高温环境会影响功率吸收能力与漏电特性,必要时按温度系数进行余量设计。

七、结论

SMCJ150CA/TR13 提供了在 150 V 等级下的双向瞬态抑制解决方案,具有较高的瞬态能量吸收能力、低漏电流与工业级工作温度范围,适合多种工业与电源保护场景。在实际设计中应关注 Vrwm 与 Vc 的匹配、热管理和浪涌次数/能量的分配,以保证长期可靠运行。如需更详细的动态参数(如具体测试波形、脉冲条件下的钳位曲线、封装机械图)建议参考厂家完整数据手册或直接向 Brightking 咨询。

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
