SMBJ36A(YANGJIE 扬杰)产品概述

一、产品简介

SMBJ36A 是一款单向瞬态电压抑制二极管(TVS),由 YANGJIE(扬杰)生产,采用 SMB(DO-214AA)封装,专为浪涌与瞬态过电压保护设计。该器件针对工业、通信、电源及汽车等系统的输入/输出端、供电线上可能出现的雷击、开关瞬变和静电放电(ESD)等瞬态事件提供有效钳位保护,能够在短时间内吸收大能量脉冲,防止下游敏感元件受损。

二、主要电气参数

  • 极性:单向
  • 反向截止电压 Vrwm:36 V
  • 钳位电压(典型):58.1 V
  • 峰值脉冲电流 Ipp:10.3 A(脉冲波形 10/1000 μs)
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs)
  • 击穿电压(Vbr):44.2 V
  • 反向漏电流 Ir:5 μA
  • 工作温度范围:-55 ℃ 至 +150 ℃

以上参数表明 SMBJ36A 能在 36 V 持续反向偏压下长期工作,并在遭遇短时高能脉冲(10/1000 μs)时将峰值电流约 10.3 A、能量吸收能力等效到 600 W 的冲击下将被钳位在约 58.1 V,具有较强的浪涌吸收能力与低漏电特性,适合保护中高电压等级的线路。

三、封装与机械特性

SMB(DO-214AA)封装是一种常见的角形功率封装,易于自动贴装(SMT)或手工焊接。该封装具有:

  • 良好的焊接可靠性与热扩散性能;
  • 适合较高能量吸收时的热量分散;
  • 在 PCB 布局上占用空间中等,适配常见电源和接口板设计。

具体机械尺寸请参照 SMB 标准封装图纸与 PCB 焊盘设计建议。

四、典型应用场景

  • 电源输入(开关电源、适配器等)对浪涌保护;
  • 通信接口(以太网、串口等)与数据线的过压保护;
  • 汽车电子(车载电源、电子控制模块)短时浪涌抑制(需结合车规等效认证判断);
  • 工业控制设备、仪表与楼宇自动化系统的防雷与开关瞬态保护。

五、选型与使用建议

  • 额定反向电压(Vrwm 36 V)适用于系统工作电压显著低于 36 V 的场合,选型时应确保工作电压(含纹波与瞬态)不会长期超过 Vrwm;
  • 对于频繁或高能量冲击的场景,应核算脉冲能量与器件 Ppp(600 W@10/1000 μs)及 Ipp(10.3 A)是否满足系统需求;多次击穿或超额能量可能导致器件永久损伤;
  • 单向器件在正向导通时表现为整流二极管,电路设计时要注意正向压降和方向布置;
  • 若系统对漏电流非常敏感(如高精度测量电路或备用电池系统),Ir = 5 μA 为参考值,应评估是否满足。

六、热管理与可靠性

  • 在浪涌事件中,器件会瞬时吸收大量能量,PCB 铜箔面积与散热设计直接影响器件的寿命与可靠性;推荐在焊盘附近保留充足铜箔并使用热沉或散热层以提升能量承受能力。
  • 长期工作在高温环境(接近+150 ℃)会加速老化,建议在实际应用中留有温度裕度并避免长期在极限温度下运行。
  • 如果应用环境中存在多次或高重复的冲击,建议做整机级的冲击测试以验证总体可靠性。

七、储存与装配注意事项

  • 储存温度、湿度应按常规半导体要求管理,避免潮湿与腐蚀性气体;
  • 推荐采用符合封装的回流焊工艺参数进行贴装,避免过高回流峰值温度和长时间高温暴露;
  • 焊接后应避免对器件施加机械应力,焊点冷却后进行清洁以防残留助焊剂侵蚀。

八、总结与建议

SMBJ36A(YANGJIE)是一款适用于中高电压保护场景的单向 TVS 器件,具有较高的瞬态功率吸收能力(600 W@10/1000 μs)与较低的漏电特性,适配 SMB 封装的自动化生产和常见 PCB 布局。选型时应核对系统最大工作电压、可能的冲击能量与工作温度,并在 PCB 热管理和可靠性验证上给予充分考虑。如需用于特殊环境(如车规级、医用或极端温度循环),建议按相应规范进行额外测试或选用具备相应认证的器件版本。

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.
