NFD3401IC-940-30 产品概述

一、产品简介

NFD3401IC-940-30 是国星光电推出的高性能940nm红外发光二极管,采用插件式3mm圆头封装(D=3mm),针对不可见光照明与光电检测场景优化。器件发射峰值波长接近940nm,半波宽仅15nm,光谱集中,适合与硅光电探测器、CMOS/CCD传感器配合使用。

二、主要光电参数

  • 峰值波长:935nm ~ 945nm(典型 940nm)
  • 半波宽(FWHM):15nm
  • 正向压降(Vf):1.1V ~ 1.4V
  • 正向电流(If):100mA(器件额定值)
  • 辐射强度(Ie):17.3 mW/sr
  • 视角:30°(半值角)
  • 耗散功率(Pd):140mW
  • 直流反向耐压(Vr):5V
  • 工作温度范围:-25°C ~ +85°C

三、主要特性与优势

  • 窄谱输出:15nm的半波宽保证光谱集中,便于滤光匹配与信噪比优化。
  • 不可见光波段:940nm为人眼不可见区域,适用于安防、遥控、夜视等对可见光干扰敏感的场合。
  • 高辐射强度:17.3 mW/sr 的输出利于中远距离照明与探测。
  • 紧凑封装:3mm插件封装便于手工焊接和快速样机验证,也利于一些小体积产品的装配。

四、典型应用场景

  • 红外遥控与近距离通信
  • 无线光学传感(光电开关、反射式传感器)
  • 夜视/红外辅助照明(监控摄像头、夜间拍摄补光)
  • 生物识别与工控设备中的不可见光照明

五、设计与使用注意事项

  • 建议在设计中加入限流电阻或恒流驱动,避免超过额定正向电流导致寿命下降。
  • 耗散功率140mW与高If配合时需注意热管理,插件封装散热受限,长时间大电流工作建议降额使用或间歇驱动。
  • 反向耐压仅5V,电路中应避免反向电压冲击,必要时并联反向保护二极管。
  • 对于需要精确光强或远距离照明的应用,建议标称If下进行标定并评估环境温度对输出的影响。

六、封装与可靠性

  • 封装形式:插件(D=3mm),引脚标准,便于手工焊接与PCB穿孔安装。常规引脚标识中短引脚为阴极(一般习惯),安装时核对数据手册脚位。
  • 环境可靠性:器件工作温度覆盖-25°C至+85°C,适应一般工业与民用环境,但在高温或高湿场景应采取防潮、防雾措施。

总结:NFD3401IC-940-30 以其集中的940nm光谱、高辐射强度与小型插件封装,适用于多种红外照明与探测应用。在系统设计中应重视限流、热管理与反向保护,以确保长期稳定运行。

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
