SMBJ36CA-AT/TR13 产品概述

一、概述与定位

SMBJ36CA-AT/TR13 是由 Brightking(台湾君耀)推出的一款高能量双向瞬态抑制二极管(TVS),封装为 SMB(DO-214AA)。该器件专为保护敏感电子线路免受瞬态过电压和静电放电(ESD)损害而设计,具备较高的峰值脉冲功率能力和宽工作温度范围,适合工业级和消费类应用中的线路及接口保护。

主要参数一览:

  • 极性:双向(Bidirectional)
  • 反向截止电压 Vrwm:36 V
  • 击穿电压 Vbr:40 V
  • 钳位电压 Vc:58.1 V(在规定脉冲条件下)
  • 峰值脉冲电流 Ipp:10.4 A
  • 峰值脉冲功率 Ppp:600 W(典型测试波形,如 10/1000 μs)
  • 反向电流 Ir:≤ 1 μA(在 Vrwm 下)
  • 工作温度:-55 ℃ 至 +150 ℃
  • 防护等级:满足 IEC 61000-4-2 ESD 保护要求
  • 封装:SMB (DO-214AA)
  • 品牌:Brightking(台湾君耀)
  • 型号后缀 TR13 表示载带盘装(Tape & Reel)

二、性能亮点

  • 高能量吸收:600 W 峰值脉冲功率能力与 10.4 A 峰值脉冲电流,使器件能在一次较强的浪涌或静电事件中吸收大量能量,保护下游元件。
  • 双向保护:适用于交流线路或双向突波情形,无需考虑极性方向,安装更方便。
  • 低泄漏:在额定工作电压 Vrwm 下反向电流极小(≤1 μA),对静态电路及高阻输入影响小。
  • 宽温度范围与可靠性:-55 ℃ 至 +150 ℃ 的工作温度范围,适应严苛环境和工业级应用。
  • 符合 ESD 标准:满足 IEC 61000-4-2 静电放电防护规范,适合需要 ESD 防护的接口(如信号口、电源口)的设计。

三、典型应用场景

  • AC/DC 电源输入过压保护(例如电源端子、适配器保护)
  • 通信接口与数据线防护(如 RS-485、CAN 总线、以太网非隔离端)
  • 工业控制与自动化设备的浪涌保护
  • 消费电子设备的前端防护(充电器输入、充电线、音频接口)
  • 需要双向瞬态抑制的场合,如交流信号线或两端都可能承受反向冲击的系统

四、使用与布局建议

  • 并联安装:TVS 二极管应并联连接在需保护的线路两端到地(或两线之间,双向场合通常并联在线路之间),以最快速夹持过电压。
  • 最短路径:在 PCB 布局上尽量将 TVS 器件放置在被保护器件的输入端与接地/参考平面之间,走线尽量短且宽,减少寄生电感。
  • 热管理:SMB 封装具备一定功率耗散能力,但在频繁冲击或高环境温度下应提供良好散热路径,例如在焊盘附近保留散热铜皮或通过热过孔连接至底层散热层。
  • 焊接与返修:遵循封装的焊接工艺规范,推荐使用符合 IPC/JEDEC 的回流焊温度曲线,避免长时间高温曝露导致器件性能退化。

五、可靠性与合规

Brightking 作为专业半导体厂商,SMBJ36CA-AT/TR13 设计注重长期可靠性,器件在温度循环、冲击和湿热环境下表现稳定。该型号符合 IEC 61000-4-2 的静电放电防护要求,适用于对 ESD 有明确规范要求的终端设备。在选型时,如需车规级认证或更严格的浪涌等级,请与供应商确认完整的认证与测评资料。

六、封装与订货信息

  • 封装类型:SMB(DO-214AA),适合潮湿环境下的自动化贴装生产和手工焊接。
  • 订货形式:常见为散装和带卷(Tape & Reel),型号后缀 TR13 表示卷带包装,便于 SMT 贴片生产线直接上料。
  • 选型提示:双向型号适用于交流与双向脉冲环境;若保护直流单向电路且需更低钳位,则可选单向 TVS 型号。

总结:SMBJ36CA-AT/TR13 以其 36 V 工作电压、58.1 V 钳位、600 W 能量吸收能力和双向结构,为需要高能量瞬态抑制与 ESD 防护的应用提供了可靠、经济的保护方案。在设计时注意 PCB 布局、散热与焊接工艺,可充分发挥其保护性能并提升系统可靠性。若需更详细的电气特性曲线、典型脉冲测试条件或封装尺寸图,请联系 Brightking 供应商索取完整数据手册。

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.
