Brightking SMAJ9.0CA/TR13 瞬态抑制二极管(TVS)产品概述

一、产品基本定位与核心应用

SMAJ9.0CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),核心定位为小体积、高可靠性的通用型浪涌防护器件,专为电子电路的瞬态过压抑制设计。其应用场景覆盖三类主流领域:

  • 消费电子:智能手机、平板、蓝牙耳机等便携设备的USB接口、充电端口防护;
  • 工业控制:PLC、传感器、电机驱动电路的开关瞬态/雷击浪涌抑制;
  • 通信设备:路由器、交换机、基站的信号/电源端口防护。

该器件的SMA小封装特性,使其能轻松集成到高密度PCB设计中,满足小型化产品的防护需求。

二、关键电气参数解析

SMAJ9.0CA/TR13的参数平衡了防护性能与电路兼容性,核心参数如下:

  1. 极性与工作电压:双向极性(无需区分电路正负),反向截止电压(Vrwm)为9V——即电路正常工作时,反向电压不超过9V则器件截止,不影响原电路功能;
  2. 过压保护核心:击穿电压(Vbr)为10V(比Vrwm高1V,避免误触发),浪涌时快速击穿(响应时间ns级),将电压钳位在15.4V以下,保护后级MCU、IC等敏感元件;
  3. 脉冲耐受能力:峰值脉冲电流(Ipp)26A,峰值脉冲功率(Ppp)400W(15.4V×26A≈400W),可有效抑制ESD、雷击浪涌、开关瞬态等干扰,多次脉冲冲击后性能稳定;
  4. 低漏电流:反向电流(Ir)仅10μA(典型值),远低于电路可接受范围,不增加功耗或影响信号完整性。

三、封装与物理特性

该器件采用SMA封装(DO-214AC),属于贴片式表面贴装封装,物理尺寸紧凑(约2.29mm×5.08mm×1.65mm),重量仅0.08g,适合自动化回流焊、波峰焊工艺,可提升生产效率。封装材料为耐高温环氧树脂,具有良好的机械强度与化学稳定性,能有效保护内部芯片。

四、可靠性与环境适应性

Brightking作为专业TVS厂商,SMAJ9.0CA/TR13的可靠性经过多重验证:

  • 宽温范围:-65℃至+150℃,可适应极端环境(如低温地区、高温工业场所);
  • 脉冲循环寿命:支持数千次脉冲冲击,性能无明显衰减;
  • 环保与认证:符合RoHS、REACH标准,部分批次通过AEC-Q101(汽车级)认证,适配汽车电子近车规场景。

五、选型与应用注意事项

  1. 电压匹配:Vrwm需≥电路正常工作的最大电压(如电路5V工作,9V Vrwm完全满足),避免误导通;
  2. 脉冲电流匹配:需根据实际浪涌源(如ESD 8kV/15kV、雷击浪涌2kV/10A)选择Ipp足够的器件,26A可覆盖多数民用/工业级场景;
  3. 极性选择:信号端口(如USB正反插)优先选双向,电源单向防护可换单向TVS,但双向更灵活;
  4. 焊接控制:回流焊峰值温度需控制在240-260℃(时间10-30s),避免过热损坏。

该器件凭借小体积、高防护、宽温特性,成为消费电子、工业控制等领域的主流浪涌防护选择。

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
