XL-3528HIR-T202 红外发射LED产品概述

一、基本身份与封装特征

XL-3528HIR-T202是成兴光(Xinglight)品牌推出的贴片式近红外发射LED,型号命名中“3528”明确其封装类型为3528贴片封装(尺寸约3.5mm×2.8mm×1.0mm),属于小型化贴片封装,适配自动化SMT贴装工艺,可集成到各类紧凑型电子设备中,满足小体积、高密度集成的设计需求。

二、核心光学性能

作为近红外发射器件,其光学参数针对性强,覆盖隐蔽发射、广域覆盖等场景:

  • 波长范围:840nm~870nm,典型值850nm,处于人眼不可见的近红外区域,适合需要隐蔽性的发射场景(如夜间监控补光);
  • 半波宽:35nm,光谱纯度适中,可匹配多数红外接收器件的光谱响应,减少杂光干扰;
  • 辐射强度:提供5mW/sr、15mW/sr两种典型值(推测与不同测试电流相关),覆盖低功耗待机到中等强度工作的需求;
  • 视角:125°宽视角,能实现大面积红外覆盖,适合需要广域感应或补光的场景(如人体感应开关、广角监控)。

三、电学性能与功率限制

电学参数决定器件工作稳定性,需严格遵循额定值:

  • 正向压降(Vf):1.6V~1.7V,属于常规硅基红外LED的压降范围,与多数驱动电路(如单片机IO口+限流电阻)匹配;
  • 耗散功率(Pd):150mW,额定功率下需控制正向电流,避免过热导致芯片老化;
  • 正向电流:最大直流正向电流100mA(实际工作电流建议不超过20mA,脉冲电流需参考详细 datasheet);
  • 直流反向耐压(Vr):5V,反向电压严禁超过该值,否则可能导致芯片击穿,需注意电路反向保护。

四、环境适应性

该器件具备较强的环境耐受能力,可适应复杂工况:

  • 工作温度:-40℃~+85℃,宽温设计可覆盖工业环境、户外低温/高温场景(如北方冬季室外设备、南方夏季户外传感器);
  • 存储温度:符合行业常规标准(-55℃~+125℃),长期存储不影响性能;
  • 抗干扰性:贴片封装抗振动、抗冲击性较好,适合长期稳定运行的设备(如安防监控、智能家居终端)。

五、典型应用场景

结合参数特性,XL-3528HIR-T202广泛应用于以下领域:

  1. 红外感应设备:人体感应开关、红外接近传感器(125°宽视角覆盖感应区域,提升检测范围);
  2. 安防监控补光:夜间监控的隐蔽补光(850nm近红外不影响人眼,避免暴露设备位置);
  3. 智能家居:智能门锁的红外感应、智能灯光的人体感应控制;
  4. 工业控制:流水线物体检测、红外计数传感器;
  5. 小型电子设备:红外遥控发射端(需匹配对应850nm波长的接收管)。

六、使用注意事项

为保证器件可靠性,需注意以下要点:

  1. 电流控制:实际工作电流建议≤20mA,避免Pd超过150mW导致过热;
  2. 反向保护:可串联二极管或稳压管做反向保护,防止静电或反向电压损坏芯片;
  3. 散热设计:3528封装散热面积有限,大电流工作时需增加PCB焊盘铜箔面积;
  4. 焊接工艺:遵循常规SMT回流焊温度曲线(峰值温度≤260℃,时间≤10s),避免高温损坏芯片;
  5. 光学匹配:接收端需选用850nm波长的红外接收管,保证感应灵敏度。

该器件凭借小型化封装、宽温适应性及合适的光学/电学参数,成为近红外感应、补光等场景的高性价比选择。

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
