NPD3535I6 产品概述

一、产品简介

NPD3535I6 为国星光电(NationStar)推出的高辐射强度近红外发光二极管,采用常见的 3535 封装,发射波长覆盖 940nm~970nm,半波宽约 50nm。该器件提供多个辐射强度等级(典型值 65 mW/sr 与 150 mW/sr),视角宽达 120°,适合广泛的红外照明与传感应用。

二、主要电气与光学参数

  • 峰值波长:940nm ~ 970nm,半波宽(FWHM)≈ 50nm
  • 正向压降(Vf):1.3V ~ 2.0V(与电流及温度有关)
  • 正向电流(If):标称 350mA(通常为脉冲峰值,应根据功耗限制评估连续工作)
  • 耗散功率(Pd):380 mW(封装耗散上限)
  • 直流反向耐压(Vr):5V(严禁长期反向偏置超过此值)
  • 辐射强度:65 mW/sr 或 150 mW/sr(按型号选择)
  • 视角:120°(半角)
  • 工作温度:-40℃ ~ +100℃

三、驱动与热管理建议

按照器件给定参数,务必注意功耗与热管理:当 If=350mA 且 Vf 在 1.3~2.0V 时,电耗约为 0.455W ~ 0.7W,已超过封装 Pd=380mW 的连续耗散能力。因此:

  • 若需 350mA,建议采用脉冲驱动,控制峰值脉冲宽度与占空比,确保平均耗散不超过 380mW,并在规格书允许范围内测试脉冲条件(脉冲宽度、重复率)。
  • 对于连续工作,应按 Pd/Vf 计算安全正向电流(例如 Vf=1.3V 时连续 If 上限约 292mA;Vf=2.0V 时约 190mA),并留有裕度。
  • 推荐在 PCB 上设计良好的散热铜箔与热沉,增加焊盘面积并使用导热介质,保证结温在安全范围内以维持光输出及寿命。

四、封装与机械特性

3535 SMD 封装,适合自动贴装与回流焊工艺。封装对光学指向性有较好控制,推荐按国星光电提供的封装图纸设计 PCB 贴装孔位与焊盘,并遵循标准回流曲线以保证焊接可靠性。

五、典型应用场景

  • 红外夜视/补光灯(安防摄像头、监控灯)
  • 距离/接近传感与手势识别(配合接收器使用)
  • 红外遥控与非可见光通信(短距离数据链)
  • 工业视觉/检测中需要不可见照明的场合

六、使用注意事项与可靠性要点

  • 严禁超过 Vr=5V 的反向电压;反向偏置会降低寿命或导致击穿。
  • 避免长期在高结温下工作,长时间高温会导致光衰与参数漂移。
  • 在驱动电路中应加入限流与过流保护,避免瞬态浪涌损伤器件。
  • 存储与使用过程中防静电(ESD)保护,按 JEDEC/厂家推荐的防护等级处理。
  • 在评估光学系统时注意器件的半波宽(50nm)与中心波长对接收器的响应匹配。

七、总结

NPD3535I6 是一款面向红外照明与传感的高强度 3535 封装 LED,波长范围适合大多数近红外成像与传感应用。其高辐射强度选项与宽视角使得系统设计灵活,但须重点关注功耗与热设计,必要时采用脉冲驱动以发挥 350mA 峰值性能并确保长期可靠性。若需更详细的电学曲线、脉冲条件或封装图纸,建议参考国星光电的完整数据手册或直接向厂商咨询。

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
