NPD3535UV1 产品概述

一、产品简介

NPD3535UV1(国星光电,封装 3535)是一款面向紫外应用的高集成小体积LED,具备两段典型峰值波长:UVC 峰值 265–285 nm(主用于杀菌/消毒类应用),UVA 峰值 390–400 nm(主用于固化、荧光检测与检测照明)。器件设计兼顾光电转换与散热要求,适合模组化阵列与贴片式组装。

二、主要电光与环境参数

  • 峰值波长:UVC 265–285 nm;UVA 390–400 nm
  • 正向压降 (Vf):5 V(典型/参考)
  • 正向电流 (If):40 mA(最大或推荐值,见下文降额说明)
  • 耗散功率 (Pd):144 mW(器件散热上限,设计时需严格控制)
  • 辐射功率(Radiant Power):UVC 4.5 mW;UVA 27 mW(在标称驱动条件下测得)
  • 发光角度:115°(半角分布,影响面照度/辐照度设计)
  • 工作温度:-40 ℃ ~ +80 ℃
  • 抗静电能力(ESD):1 kV(HBM 类似等级,需工艺防护)
  • 直流反向耐压 (Vr):5 V(切勿长期反向偏置超出此值)

三、封装与热机械特性

  • 封装:3535(3.5 mm × 3.5 mm SMD),利于高密度阵列排列与自动贴装。
  • 建议在 PCB 上设计合适的焊盘与大面积散热铜箔(尤其底部热垫),并通过过孔连接至多层地铜以降低结温。
  • 注意回流焊温度曲线与焊点可靠性,避免过高温度或长时间保温导致光输出衰减。

四、使用建议与设计注意事项

  1. 功率与降额:器件标称 Pd=144 mW,但 Vf×If 在 5 V × 40 mA ≈ 200 mW,已超过 Pd 指标。设计时应:
    • 采用脉冲驱动或将连续驱动电流降额至安全区(例如 < 30 mA,具体需结合热阻仿真与实测);
    • 在数据手册/样片测得的实际 Vf 下计算耗散并保证不超过 Pd。
  2. 恒流驱动:建议使用恒流源供电,避免电流过冲;使用 PWM 调光时考虑频率与峰值电流限制。
  3. 反向与 ESD:禁止超过 Vr=5 V 的反向偏置;生产与装配阶段实施 ≥1 kV ESD 防护(佩戴腕带、使用离子风等)。
  4. 热管理:确保热阻路径低,器件结温不超限;在高 Duty 或密集阵列时加入主动散热或更大铜面积。
  5. 光学与安全:UVC 对皮肤与眼睛有伤害,应在系统层面加入屏蔽、互锁与安全指示;UVA 也有潜在危害,应按标准防护。

五、典型应用

  • UVC(265–285 nm):小型空气/表面/水体消毒模块、电子器件局部杀菌、食品与医疗器具消毒。
  • UVA(390–400 nm):紫外固化(胶黏剂/涂料)、荧光显影/荧光激发、无损检测与验钞、指示与检测照明。
  • 适用于需要小尺寸、高密度阵列与自动化贴装的消费与工业产品。

总结:NPD3535UV1 在小封装下提供明确的 UVC/UVA 光谱输出,适合多种紫外应用。但在电热设计上需特别注意 Pd 与 Vf×If 的关系,采取降额或脉冲策略并做好散热与安全防护,方能发挥稳定可靠的性能。

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
