NTD3528I7 产品概述

一、产品简介

NTD3528I7 是国星光电(NationStar)推出的一款高效红外发光二极管,采用常见的 3528 SMD 封装。器件中心波长位于 940nm~970nm 波段,半波宽约 40nm,具备窄视角和较高的辐射强度,适用于需要定向红外照明或光电检测的各类产品与系统。

二、主要性能参数

  • 封装:3528 SMD
  • 波长(中心/范围):940nm ~ 970nm
  • 半波宽(FWHM):约 40nm
  • 正向压降(Vf):1.3V ~ 2.1V
  • 典型辐射强度:20 mW/sr(标称)
  • 视角(半角):30°
  • 额定/峰值正向电流(If):100 mA(请注意区分脉冲与连续工作)
  • 最大耗散功率(Pd):90 mW
  • 直流反向耐压(Vr):5 V
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、产品特点

  1. 窄光束角(30°)——便于实现远距、定向照明或聚焦探测,减少杂散光。
  2. 高辐射强度——在相近尺寸和驱动条件下,提供较强的发射光功率,提升传感器的响应距离与稳定性。
  3. 适用波段广——940~970nm 范围覆盖常见夜视/监控和接收器谱响应峰值,系统兼容性好。
  4. 小型化封装(3528)——利于面阵排列或在空间受限的模块中布置。

四、典型应用场景

  • 夜视监控(IR 补光灯、安防摄像头)
  • 红外遥控与通信(短距离链路、设备间信号)
  • 接近/检测与测距传感(光电开关、线阵传感器)
  • 医疗与工业光学检测(不可见光照明、光学编码)
  • 汽车夜视与泊车辅助(需配合热管理与认证)

五、使用与设计建议

  • 功率与电流限制:器件耗散功率 Pd = Vf × If,按最大 Pd=90 mW 计算,连续工作时的最大 If 受 Vf 影响(If_max ≈ Pd/Vf),当 Vf 为 2.1V 时 If_max ≈ 42.9 mA。为保证可靠性,建议持续工作电流取保守值(如 ≤ 40 mA),100 mA 建议仅在受控脉冲驱动、严格限制占空比和频率下使用。
  • 驱动方式:优先采用恒流驱动,避免直接恒压驱动。脉冲驱动可提高峰值输出,但需计算平均功耗并满足 Pd 与热稳定性要求。
  • 热管理:尽管功耗不高,合理的 PCB 铜箔面积和焊盘设计有助于散热与长期稳定性。
  • 光学配合:窄视角适合配合光学透镜或反射杯进一步控制发散角度,提高目标照明集中度。
  • 反向保护:避免超过 Vr=5V 的反向偏压,设计中可加防反接二极管或限流电路。

六、可靠性与存储

  • 工作温度范围宽(-40℃~+85℃),适合多种工业与消费环境。
  • 建议按照国星光电提供的焊接与回流曲线进行 SMT 工艺,避免过热导致性能变化。
  • 存储与搬运时注意防潮、防静电;如需长期库存,请参照厂方的包装与保质建议。
  • 如需产品认证(如 RoHS、AEC‑Q 等)或更详细的电学/光学曲线、脉冲极限与寿命数据,请联系国星光电获取正式数据手册。

若需我提供典型驱动电路、热设计计算示例或按您具体应用给出匹配建议,可说明应用场景与目标工作点,我将给出更详细的工程建议。

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
