SMBJ110A/TR13 — 110V 单向 TVS 二极管(SMB / DO-214AA)

一、产品概述

SMBJ110A/TR13 是由 Brightking (台湾君耀) 提供的一款单向瞬态电压抑制(TVS)二极管,采用 SMB(DO-214AA)封装。该器件专为抑制高能脉冲过电压和保护敏感电子元件设计,具有快速钳位响应、低反向泄漏和宽工作温度范围,适用于工业电源、直流母线及通信设备等需要对瞬态浪涌进行保护的场合。

二、主要参数

  • 极性:单向
  • 反向工作电压 Vrwm:110 V
  • 击穿电压 VBR:122 V
  • 钳位电压:177 V
  • 峰值脉冲电流 Ipp:3.4 A
  • 峰值脉冲功率 Ppp:600 W
  • 反向电流 Ir:1 μA(典型/在 Vrwm 条件下)
  • 工作温度范围:-65 ℃ ~ +150 ℃
  • 类型:TVS 二极管
  • 封装:SMB(DO-214AA)
  • 型号:SMBJ110A/TR13
  • 品牌:Brightking(台湾君耀)

三、电气特性说明

SMBJ110A/TR13 在反向工作电压(Vrwm)下保持高阻态,反向泄漏电流非常小(约 1 μA),可在正常工作条件下减少能量损耗与热升。遇到瞬态过电压时,器件在接近 VBR(122 V)时进入雪崩区并迅速导通,将尖峰能量钳位至约 177 V,从而保护后级电路。器件的峰值脉冲功率为 600 W,峰值脉冲电流 3.4 A(按厂方及行业标准脉冲测量条件),可承受短时高能浪涌。

四、典型应用场景

  • 工业直流母线与电源模块过压保护(例如 48V/72V/110V 系统)
  • 开关电源及逆变器输入输出接口的浪涌抑制
  • 通信与中继设备的线路防护
  • 电池管理及储能系统的瞬态浪涌防护
  • 需要中等能量浪涌吸收能力的电子装置

五、封装与安装要点

SMB(DO-214AA)表面贴装封装,适配常见的 PCB 回流焊工艺。建议在 PCB 布局时:

  • 将 TVS 靠近被保护节点(输入端/接口)放置以降低走线感应电压
  • 提供足够的焊盘和散热面积以利于瞬态能量分散
  • 对于高能量或多次浪涌场合,考虑并联或级联保护方案

六、工作与可靠性提示

器件额定的峰值脉冲功率与电流基于标准脉冲波形测试,长期重复承受接近额定值的浪涌会影响寿命;若应用中存在频繁或极高能量脉冲,应选用更高能量等级或并联多只器件。产品在 -65 ℃ 至 +150 ℃ 的温度范围内可稳定工作,但在极端温度下仍需关注焊接工艺与封装机械应力。

七、使用建议与注意事项

  • 选型时确认 Vrwm 与系统最大工作电压匹配,留有适当裕度以避免误触发;
  • 布线尽量缩短从保护点到被保护器件的导线长度,以降低串联感抗;
  • 储存与操作遵循防静电措施,避免静电和机械冲击;
  • 按照供应商的回流焊曲线进行焊接,避免超出封装的热应力极限。

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
