1.0SMB30CA/TR13 产品概述

一、概述

1.0SMB30CA/TR13 是 Brightking(台湾君耀)推出的一款双向瞬态电压抑制器(TVS)二极管,采用 SMB(DO-214AA)封装,专为抑制电源突波、雷击感应和电路中的瞬态过压而设计。该器件在设计上兼顾小体积、高能量吸收能力与良好的热稳定性,适用于工业、通讯、电源及汽车电子等需要中等能量瞬态保护的场合。

二、主要电气参数

  • 极性:双向(bidirectional),适合交流或双向浪涌保护
  • 反向截止电压 Vrwm:25.6 V
  • 击穿电压(典型):28.5 V
  • 钳位电压 Vc(在指定脉冲下):41.4 V
  • 峰值脉冲电流 Ipp:24.5 A
  • 峰值脉冲功率 Ppp:1 kW(脉冲能量能力,通常按标准脉冲波形测定)
  • 反向漏电流 Ir:1 μA(静态小漏电,有利于低功耗系统)
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 封装:SMB(DO-214AA),适合表面贴装工艺
  • 类型:TVS 二极管,型号:1.0SMB30CA/TR13(TR13 表示卷带包装/便于贴片生产线使用)

三、产品特点与优势

  • 双向抑制:对正负极性瞬态均能快速夹位,适用于交流信号线或无固定极性的电源总线。
  • 高能量吸收:1 kW 峰值脉冲功率与 24.5 A 峰值脉冲电流能力,可应对常见的雷击感应和开关瞬态。
  • 低漏电:1 μA 的漏电特性适合对待机功耗敏感的应用场合。
  • 宽温度范围:工作温度覆盖工业级与部分汽车级要求,可靠性高。
  • SMB 封装:良好的热散能力与机械强度,适合自动贴装与波峰/回流焊接流程。

四、典型应用场景

  • 电源输入保护(DC 电源总线、模块化电源)
  • 通信设备(基站、路由器、交换机端口保护)
  • 工业控制与自动化设备(PLC、驱动器供电线)
  • 汽车电子(车载非关键回路瞬态抑制)
  • 测量仪器与消费类电子(接口与外部连接端口防护)

五、选型与使用建议

  • 确认工作电压:选择 Vrwm 与系统工作电压匹配,Vrwm=25.6 V 适合 24 V 左右系统,避免在常态下进入击穿区。
  • 考虑钳位能力:钳位电压 41.4 V 表示在指定 Ipp 下对被保护电路的最大瞬态电压,确保下游器件能承受该电压或配合额外的限流元件。
  • 考量脉冲波形:峰值电流与功率通常按标准脉冲(如 10/1000 μs)测定,实际脉冲波形差异会影响吸收能力,必要时参考厂商波形数据。
  • 热管理与布线:SMB 封装具有一定散热能力,但在多次高能量脉冲下需要合适的散热与可靠的焊盘布线。
  • 并联/串联注意:并联可提升能量吸收但需匹配器件特性;串联通常不用于 TVS 实现保护。

六、可靠性与注意事项

  • 不可作为长期高电流通路;TVS 设计用于瞬态事件瞬间吸收能量而非持续导通。
  • 漏电会随温度上升增加,需考虑高温工况对待机功耗的影响。
  • 建议遵循厂商的焊接与存储规范,采用适用于 SMB 的回流曲线与防潮处理以保证焊接可靠性。
  • 选型时参考完整数据手册的动态特性曲线(击穿分布、钳位曲线、能量吸收曲线)以确保系统保护裕量。

七、结论

1.0SMB30CA/TR13 提供稳健的双向瞬态保护,适合 24 V 级及接近电压系统的浪涌防护需求。结合其低漏电、高脉冲能量能力和 SMB 封装,适用于多种工业与通讯场景。在最终设计中,请结合实际应用脉冲类型、热环境与下游器件耐压能力,参考厂商完整数据手册以完成可靠的保护设计。

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
