XL-2835UVA-02 贴片发光二极管产品概述

XL-2835UVA-02是成兴光(Xinglight)推出的一款SMD2835封装小功率UVA波段贴片发光二极管,主打低功耗、宽角度覆盖与稳定紫外输出,适用于多种小型化紫外应用场景。

一、产品基本定位

该器件属于0.2W级(200mW)UVA紫色系LED,采用标准化SMD2835表面贴装封装(尺寸2.8×3.5mm),适配自动化贴装产线,可满足高密度PCB布局需求。核心定位为低成本、高可靠性的小型紫外输出器件,覆盖消毒、固化、检测等细分场景。

二、核心性能参数详解

2.1 波长与光谱特性

  • 峰值波长:395nm(属于UVA波段范畴,对多数有机物、微生物具有有效作用);
  • 半波宽:20nm,光谱集中性优异,减少无效波长的能量损耗,提升紫外作用效率;
  • 辐射功率:90mW(额定工作状态下稳定输出,同功率段表现优于部分竞品)。

2.2 电学性能参数

  • 正向压降(Vf):3.6V(典型值,驱动电路设计需匹配此压降);
  • 额定正向电流(If):60mA(持续工作电流上限,过流易加速器件老化);
  • 耗散功率(Pd):200mW(0.2W,小功率设计降低散热压力);
  • 反向耐压(Vr):5V(需避免反向电压超此值,防止器件击穿);
  • 反向电流(Ir):≤5uA(反向漏电极小,提升电路整体稳定性)。

2.3 光学与环境适应性

  • 发光角度:120°(宽角度输出,适合大面积照射或多器件组合覆盖);
  • 工作温度范围:-40℃~+85℃(覆盖工业级高低温场景,如户外设备、低温仓库应用);
  • 抗静电能力:2kV(满足一般生产、使用中的ESD防护需求,无需额外复杂防护)。

三、典型应用场景

XL-2835UVA-02凭借小功率、宽角度与稳定紫外输出,可应用于以下场景:

  1. 小型紫外消毒设备:便携式消毒棒、桌面消毒器、牙刷消毒盒等(低功耗适合手持/小型化设计,395nm对大肠杆菌、金黄色葡萄球菌等具有灭活作用);
  2. 紫外固化辅助:小型UV胶固化(如手机屏幕维修、饰品粘合、电子元件固定);
  3. 检测类设备:荧光检测(珠宝鉴定、生物样本荧光标记检测)、伪钞鉴别(部分货币荧光防伪特征适配395nm);
  4. 植物补光辅助:部分多肉植物、兰花等对UVA有需求,宽温设计适合温室补光;
  5. 特殊指示:医疗设备状态提示(消毒设备工作指示)、工业设备紫外警示。

四、封装与可靠性设计

  • 封装形式:SMD2835表面贴装,采用耐高温树脂封装,焊接兼容性好(适配回流焊、波峰焊工艺);
  • 散热设计:封装底部设有散热焊盘,需配合PCB合理布局(如增加散热铜箔),避免局部过热;
  • 可靠性保障:宽温范围覆盖极端环境,反向漏电小降低电路干扰,抗静电能力满足量产要求。

五、选型与使用注意事项

  1. 驱动电流控制:持续工作电流不得超过60mA,建议采用恒流驱动(50-60mA区间),避免电压驱动导致的电流波动;
  2. 散热设计:虽为小功率,但需保证PCB散热pad与铜箔连接良好,避免工作温度超过85℃;
  3. 反向电压防护:若电路存在反向电压,需增加反向保护二极管,防止超过5V反向耐压;
  4. 焊接工艺:回流焊温度需符合SMD2835标准(峰值温度260℃以内,时间≤10s),避免损坏器件。

这款器件在同封装同功率段中,具有光谱集中、宽温适应、易贴装等优势,是小型紫外应用场景的高性价比选择。

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
