NCD3012I1 红外发光二极管产品概述

一、产品定位与应用场景

NCD3012I1是国星光电推出的小尺寸SMD近红外发光二极管,针对消费电子、智能家居、安防监控、工业控制等领域的近距离感应、定向传输需求设计,主打“小体积、低功耗、高定向性”三大核心特性,可替代传统直插红外LED,适配小型化、高密度PCB布局。

二、核心参数深度解析

(一)光学性能参数

  • 波长范围:930nm~970nm(近红外区间,人眼不可见,避免视觉干扰);
  • 半波宽:48nm(光谱纯度较高,减少多光源交叉干扰,提升感应准确性);
  • 辐射强度:40mW/sr(中等功率水平,平衡传输距离与功耗);
  • 视角:20°(窄角设计,红外辐射集中,定向传输效率提升30%以上,适合精准感应场景)。

(二)电学性能参数

  • 正向压降(Vf):1.6V(低功耗设计,适配3.3V、5V常用电源,无需复杂电源转换);
  • 额定正向电流(If):70mA(对应功耗112mW,远低于最大耗散功率140mW,长期工作可靠性高);
  • 反向耐压(Vr):5V(需注意电路防护,避免反向电压超差损坏器件)。

(三)环境适应性参数

  • 工作温度:-40℃~+85℃(覆盖户外低温、工业高温等复杂场景);
  • 存储兼容性:基于工业级设计,可兼容常规电子元器件存储条件(短期存储温度-55℃~+125℃)。

三、封装与可靠性设计

该器件采用3×1.2mm SMD封装,具备以下优势:

  1. 小体积高密度:尺寸紧凑,适合智能手环、遥控器等小型产品内部布局;
  2. 自动化兼容:贴片式封装适配回流焊工艺,提升批量生产效率;
  3. 高可靠性:国星光电优化了防潮、抗冲击性能,符合GB/T 14590-2017红外LED分规范,批量应用参数一致性达±5%以内,1000小时老化故障率低于0.1%。

四、性能优势总结

  1. 小体积省空间:3×1.2mm封装支持多器件密集布局(如遥控器多通道发射);
  2. 低功耗高效能:功耗仅为同类直插器件的60%,延长电池续航;
  3. 高定向传输:20°窄角使红外辐射集中,相同功率下传输距离提升30%;
  4. 宽温稳定:-40℃~+85℃范围覆盖绝大多数应用场景;
  5. 批量可靠:国星光电成熟工艺保障参数一致性,降低售后风险。

五、典型应用案例

  1. 智能家居人体感应:智能门锁、智能灯的人体接近模块,感应距离5~8m,隐蔽安装不影响外观;
  2. 消费电子遥控器:电视、空调遥控器发射管,适配主流接收头(如TSOP38238),传输距离≥10m;
  3. 安防定点补光:小型监控摄像头辅助补光,窄角设计避免干扰周边区域,夜间成像清晰;
  4. 工业位置检测:流水线物体传感器,小尺寸适合狭小工位,感应精度±1cm。

六、选型与使用注意事项

  1. 电源设计:3.3V电源串联24Ω/1/8W限流电阻(计算:R=(3.3-1.6)/0.07≈24Ω);
  2. 反向防护:增加反向二极管或稳压管,确保反向电压≤5V;
  3. 散热要求:长期70mA工作时,PCB铜箔面积≥5mm²,避免局部过热;
  4. 焊接工艺:回流焊峰值温度≤260℃,焊接时间≤10s,禁止手工高温焊接;
  5. 存储条件:常温干燥环境存储,避免湿度≥80%长期暴露。

NCD3012I1凭借其小体积、低功耗、高定向性等优势,成为消费电子、智能家居等领域红外感应应用的优选器件,国星光电的成熟工艺为批量应用提供可靠保障。

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
