NTD3528U1 产品概述

一、产品简介

NTD3528U1 是国星光电推出的一款高性能紫外(UVA)3528贴片LED,峰值波长集中在365–370 nm,采用标准3528(3.5×2.8 mm)封装。该器件设计用于高辐射功率输出的短波紫外应用,兼顾光学指向性和散热性能,适合自动化贴装与常规回流焊工艺。

二、光电性能(关键参数)

  • 峰值波长:365 nm ~ 370 nm(适合激发荧光材料与紫外固化)
  • 辐射功率(Pr):140 mW(典型值,驱动电流150 mA)
  • 半波宽(FWHM):10.5 nm(谱线窄,光谱集中,适合荧光激发)
  • 发光角度:120°(广角照射,覆盖面大)
  • 正向压降(Vf):4.2 V(典型)
  • 正向电流(If):150 mA(额定)
  • 耗散功率(Pd):630 mW(器件最大耗散)

根据典型数据,电光转换效率较高(辐射功率/电功率 ≈ 20%左右),在紫外照明与激发类应用中表现优异。

三、热特性与工作环境

  • 工作温度范围:-20 ℃ ~ +65 ℃
  • 耗散功率上限 630 mW,实际使用中需合理控制结温与PCB散热。建议在设计时预留足够的铜箔面积或接入散热片,避免长时间高温环境导致寿命下降。
  • 为保证长期稳定性,建议在高环境温下对正向电流进行降额(derating)。

四、驱动方式与线路建议

  • 建议采用恒流驱动,额定驱动电流为150 mA。若采用串联电阻的简易驱动方式,应按 R = (Vsup - Vf)/If 计算并选用合适功率的电阻。示例:12 V 供电时 R ≈ (12 − 4.2)/0.15 ≈ 52 Ω,电阻功率约 1.17 W,应选用 ≥2 W 的电阻以保证可靠性。
  • 支持脉冲驱动以实现更高瞬时辐射输出,但脉冲宽度与占空比必须在器件热限制内,避免超过Pd导致损坏。
  • 由于发光角度较大,若需准直或聚光效果,应配合光学透镜或反射器使用。

五、封装与可制造性

  • 封装:3528 SMD,兼容常见贴装与回流焊工艺;适合大规模自动化生产。
  • 建议参照国星光电的焊接与回流曲线进行工艺控制,以保证焊点可靠性与器件性能一致性。

六、可靠性与防护建议

  • 抗静电能力:4 kV(HBM),生产与装配过程中应实施ESD防护措施(佩戴防静电手环、使用防静电工作台等)。
  • 使用与维护中注意紫外安全:365–370 nm 的紫外光对皮肤与眼睛具有潜在风险,建议在设计中加入防护罩或滤光措施,避免人员直视或直接暴露于强紫外光下。
  • 存储与操作避免高湿、高温及强光直射,延长器件寿命。

应用场景:紫外荧光激发、材料/墨水固化(点胶、印刷)、伪钞/证件验证、法医/矿物检测、紫外照明与检测等领域。总体而言,NTD3528U1 在高输出、窄谱、稳定性与可生产性之间取得良好平衡,是紫外照明与检测类产品开发的可靠选择。若需更详细的电学、热学参数或回流曲线,请参考国星光电官方资料或联系供应商获取器件详细数据手册。

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
