国星光电NTD3528I5红外LED产品概述

一、产品定位与封装基础

国星光电NTD3528I5是一款SMD2835-2P封装的近红外LED,主打中小功率、宽视角、高集成性,核心面向感应、补光类场景的紧凑型设计需求。

其封装尺寸符合行业标准(约2.8mm×3.5mm×0.8mm),2引脚贴片式结构兼容自动化贴装生产线,安装便捷且占用PCB空间极小,适合迷你安防摄像头、小型感应模块等对体积敏感的产品。封装采用耐高温环氧树脂材料,兼顾光学透光性与机械强度,可适配常规回流焊、波峰焊工艺,无需特殊制程要求。

二、核心光电性能解析

该产品的关键参数直接决定了适用场景,具体特性如下:

1. 正向驱动特性

  • 正向压降(Vf):1.4V2.2V(典型值约1.8V),驱动电压范围宽,搭配10Ω20Ω限流电阻即可实现稳定驱动,无需复杂恒流电源;
  • 额定正向电流(If):100mA,属于中小功率范畴,兼顾信号强度与功耗平衡,适合长期连续工作场景。

2. 功率与辐射性能

  • 最大耗散功率(Pd):98mW,热稳定性良好,持续工作时若控制电流在80mA以内,可避免过热衰减;
  • 辐射强度:12mW/sr,中近距离(1~5米)感应/补光场景下信号充足,无需多灯珠拼接即可覆盖常规视野。

3. 光谱与视角特性

  • 发射波长:840nm~870nm(近红外区域),人眼不可见,适合隐蔽补光/传感;
  • 半波宽:40nm,光谱分布相对集中,既保证信号纯度,又避免过窄波长导致的抗干扰性下降;
  • 视角:125°宽视角,光线覆盖范围广,单颗即可满足楼道感应、监控补光等大面积需求。

4. 反向与耐压特性

  • 直流反向耐压(Vr):10V,可承受常规电路反向脉冲(如电源波动),提升电路兼容性。

三、典型应用场景

结合参数特性,NTD3528I5可适配以下主流场景:

1. 安防监控补光

夜间监控摄像头需隐蔽补光,该产品波长在近红外,不干扰画面且无视觉暴露;125°宽视角可覆盖摄像头视野,单颗灯珠即可满足10米内补光需求,降低多灯珠成本。

2. 智能家居感应

人体感应开关、自动门传感器、智能灯光控制等场景,12mW/sr辐射强度可穿透薄窗帘、塑料外壳,-40℃~+85℃工作温度适应室内外环境(如阳台感应灯)。

3. 工业控制检测

光电开关、物料计数、位置传感器等工业场景,宽视角与稳定辐射强度可实现精准检测,SMD封装适合集成到小型传感器模块(如流水线计数传感器)。

4. 消费电子配件

红外遥控器(部分型号)、智能穿戴设备的红外辅助传感(如心率监测),体积小、功耗低的特点符合便携性需求。

四、可靠性与环境适应性

国星光电的品牌技术积累让该产品具备以下可靠性优势:

  • 温度适应性:-40℃+85℃宽温范围,可应对户外严寒(北方监控)、工业车间高温(30℃50℃环境);
  • 耐候性:封装防潮、防轻微腐蚀,适合浴室感应、户外灯箱等潮湿场景;
  • 寿命表现:额定参数下工作寿命达5万小时以上,满足24小时连续运行的监控系统需求。

五、选型与使用注意事项

为确保性能稳定,使用时需注意:

  1. 电流限制:正向电流不得超过100mA,持续工作建议控制在80mA以内,避免Pd超98mW;
  2. 焊接工艺:回流焊峰值温度≤265℃,时间≤10秒,避免高温损坏芯片;
  3. 散热设计:高负载工作时,PCB需预留散热铜箔(≥10mm²),提升热传导效率;
  4. 存储条件:未使用时存于干燥环境(湿度≤60%),温度-10℃~+40℃,避免封装受潮。

NTD3528I5以高性价比、宽适配性成为感应与补光领域的主流选型,适合对体积、成本、可靠性有综合要求的产品设计。

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
