SMBJ15A-AT/TR13瞬态抑制二极管(TVS)产品概述

SMBJ15A-AT/TR13是台湾君耀电子(Brightking)推出的单向瞬态抑制二极管(TVS),专为15V等级电子系统的过压防护设计,采用SMB(DO-214AA)表面贴装封装,具备高可靠性、宽温范围及强瞬态冲击耐受能力,广泛适配工业控制、汽车电子、通信设备等场景。

一、产品核心定位与品牌背景

君耀电子(Brightking)作为台湾老牌过压防护器件厂商,专注研发20余年,产品以“高一致性、宽温可靠性”著称,在汽车电子、工业自动化领域符合严苛标准。SMBJ15A-AT/TR13属于君耀SMB系列TVS主流型号,核心定位为12V/15V系统的瞬态浪涌防护,解决静电放电(ESD)、雷击浪涌、电源开关瞬态等问题。

二、关键电气参数及性能优势

该型号参数围绕“电压匹配+瞬态功率耐受”设计,核心性能突出:

1. 电压参数精准适配主流系统

  • 反向截止电压(Vrwm):15V:对应系统最大工作电压,适配12V车载/工业系统(典型工作电压10.8-14.4V)、15V低压电源,避免TVS在正常工作时导通;
  • 击穿电压(Vbr):16.7V:反向电压超此值时,TVS以ns级速度导通,快速启动防护;
  • 钳位电压(Vc):24.4V(@Ipp=24.6A):峰值脉冲下将电压限制在24.4V以内,保护MCU、传感器等敏感器件。

2. 瞬态冲击耐受能力强

  • 峰值脉冲功率(Ppp):600W:单次浪涌最大功率耐受值,覆盖IEC 61000-4-5标准中常见的2/10μs脉冲;
  • 峰值脉冲电流(Ipp):24.6A:600W功率下的峰值泄放电流,可应对大电流浪涌;
  • 反向漏电流(Ir):1uA(@Vrwm):静态漏电流极小,不影响低功耗系统(如电池供电设备)运行。

3. 宽温工作范围

  • 工作温度:-55℃~+150℃:覆盖工业级、汽车级温度要求,可在极端环境(高温车载、低温户外)稳定工作。

三、封装形式与可靠性设计

采用SMB(DO-214AA)表面贴装封装,具备以下优势:

  • 尺寸紧凑:封装尺寸约2.5mm×5.2mm×1.0mm,适配高密度PCB(如小型车载模块、便携设备);
  • 焊接可靠:支持回流焊(峰值260℃≤40s),引脚与封装结合牢固,抗机械应力;
  • 极性清晰:表面印有“A”标识(单向TVS阳极),便于安装时确认方向,避免接反失效。

四、典型应用场景

因“电压适配广、封装小、宽温可靠”,主要应用于:

  1. 汽车电子:12V车载系统(MCU、传感器、显示屏)浪涌防护;
  2. 工业控制:PLC、传感器模块、低压电源过压保护;
  3. 通信设备:小型基站、路由器、RS485接口防护;
  4. 消费电子:12V锂电池组、便携充电设备瞬态防护;
  5. 户外设备:太阳能控制器、户外监控宽温防护。

五、选型与应用注意事项

为确保防护效果,需注意:

  1. 极性确认:单向TVS需区分阳极(A端)和阴极,接反会失效;
  2. 电压匹配:Vrwm≥系统最大工作电压(如12V系统选15V);
  3. 功率校验:参考IEC 61000-4-5标准,确认600W是否满足浪涌需求;
  4. 并联使用:若需更大电流,可多个同型号并联(注意均流);
  5. 焊接规范:避免过温(>260℃/40s),防止器件可靠性下降。

综上,SMBJ15A-AT/TR13凭借君耀品质、精准参数及紧凑封装,成为15V系统过压防护的高性价比选择,适用于对可靠性、体积有要求的各类电子设备。

Sourcing availability signal

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
