Brightking SMAJ90CA/TR13 TVS管产品概述

一、产品基本信息

SMAJ90CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),核心功能为电子电路的静电放电(ESD)与浪涌过压防护。该型号采用SMA(DO-214AC)贴片封装,体积紧凑,适配高密度PCB设计,广泛应用于工业、通信、新能源等领域的中高压电路防护场景。

二、核心电气参数解析

参数直接决定TVS管的防护能力,SMAJ90CA/TR13的关键参数及实际意义如下:

1. 极性与电压耐受基础

  • 双向极性:无需区分正负极,可直接并联在信号/电源线路两端,简化电路设计;
  • 反向截止电压(Vrwm):90V:正常工作时器件可承受的最高反向电压(不击穿),需匹配电路最大工作电压(如电路峰值电压≤85V时,90V Vrwm可满足需求);
  • 击穿电压(Vbr):100V:反向击穿的典型触发电压,击穿后器件进入低阻态,快速钳位电压。

2. 浪涌防护核心能力

  • 钳位电压(Vc):146V:施加峰值脉冲电流(Ipp)时,器件两端的最高电压,直接决定被保护器件的安全上限(需Vc<被保护器件最大耐压);
  • 峰值脉冲电流(Ipp):2.7A:8/20μs浪涌波形下,器件可承受的最大脉冲电流;
  • 峰值脉冲功率(Ppp):400W:8/20μs波形下的最大脉冲功率,反映器件的浪涌能量耐受能力。

3. 静态与环境适应性

  • 反向漏电流(Ir):1μA(@Vrwm):低漏电流特性,不影响电路正常工作(无额外功耗/干扰);
  • 工作温度范围:-65℃~+150℃:宽温设计,可适应工业级高低温环境(如户外设备、车载系统)。

三、封装与可靠性特性

SMAJ90CA/TR13采用SMA(DO-214AC)贴片封装,具备以下优势:

  1. 小体积:封装尺寸约2.3mm×2.0mm×1.0mm,适合高密度PCB布局(如服务器、通信模块);
  2. 焊接兼容性:符合无铅回流焊工艺(峰值温度260℃±5℃,焊接时间≤30s),手工焊接需控制温度≤350℃、时间≤5s;
  3. 品牌可靠性:通过RoHS认证,且经过高温老化、ESD(人体模型HBM:±8kV)等测试,长期稳定性优异。

四、典型应用场景

结合参数特性,该器件适用于以下中高压电路防护:

  1. 工业自动化:PLC、伺服驱动器、变频器的辅助电源(24V~90V)防护;
  2. 通信基站:射频中频电路、电源模块的ESD与浪涌防护;
  3. 新能源设备:电动车BMS低压控制电路、光伏逆变器辅助电源防护;
  4. 消费电子高压模块:快充电源(90V以内输出)、液晶电视背光驱动电路防护。

五、选型与使用注意事项

  1. 选型匹配:
    • Vrwm需≥电路最大工作电压(如电路峰值80V,选90V Vrwm合适);
    • Vc需<被保护器件最大耐压(如MCU耐压150V,146V Vc可满足);
  2. 布局建议:靠近被保护端口(连接器、电源输入),减少引线电感,提升防护响应速度;
  3. 并联扩容:浪涌电流超2.7A时,可并联多个同型号器件(需保证均流,匹配相同封装参数);
  4. 静电防护:存储/运输需防静电(避免人体直接接触引脚)。

总结

Brightking SMAJ90CA/TR13 TVS管以双向防护、90V中高压耐受、小体积、宽温特性为核心优势,平衡了防护能力与应用灵活性,是工业、通信、新能源等领域中高压电路过压防护的可靠选择。

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
