S2-2835UVTA-0.2W 紫外LED产品概述

一、产品核心定位与应用场景

S2-2835UVTA-0.2W是拓展光电(TUOZHAN) 推出的SMD2835封装近紫外LED,聚焦小功率、广角度、宽温适应的应用需求,峰值波长覆盖390nm~400nm(近紫外区域),主要面向对体积、功耗敏感的小型设备,典型应用场景包括:

  • 小型UV固化(手机维修UV胶、电子元件封装胶固化);
  • 便携式光催化净水(辅助分解水中微量有机物);
  • 智能感应触发(自动洗手液机、小型安防设备的紫外触发模块);
  • 小型美容仪器辅助(嫩肤、祛痘仪器的紫外辅助环节)。

二、关键性能参数详解

1. 光学性能

  • 峰值波长390nm~400nm:处于近紫外“有效作用区间”,对常见UV胶、光催化剂的吸收匹配度高;
  • 半波宽10nm:波长集中度高,避免无效光谱浪费,提升目标应用效率;
  • 发光角度120°:广角度覆盖,无需额外透镜即可满足小面积工件的均匀照射需求。

2. 电学性能

  • 正向压降3.3V:与常规5V电源系统适配性好,无需复杂升压/降压电路;
  • 正向电流60mA(额定):标称耗散功率180mW(接近0.2W),小功率设计适合电池供电设备;
  • 反向耐压5V/反向电流10uA:反向漏电极低,减少反向功耗损耗,提升长期可靠性。

3. 环境与可靠性

  • 工作温度-40℃~+85℃:宽温范围覆盖工业级应用(如户外小型设备)和常规室内场景;
  • 抗静电能力2kV:符合IEC 61000-4-2静电防护标准,生产/使用过程中不易因静电损坏。

三、封装与可靠性设计

采用SMD2835贴片封装(常规尺寸2.8×3.5×0.8mm),具备以下设计优势:

  1. 自动化贴装适配:适合SMT流水线生产,降低人工成本;
  2. 导热优化:封装底部采用高导热焊盘,配合PCB板散热设计,可稳定承载180mW功耗;
  3. 结构防护:环氧树脂封装层耐磨损、抗冲击,适应小型设备的紧凑安装环境。

四、典型应用案例

1. 手机维修小型UV固化灯

某手机维修店采用该LED替代传统大功率固化灯,单颗产品配合5V电源即可满足屏幕胶、按键胶的小面积固化(照射时间约30秒),体积缩小60%,功耗降低70%。

2. 便携式光催化净水杯

某户外品牌净水杯内置3颗该LED,结合光催化剂膜,可在10分钟内分解水中90%以上的邻苯二甲酸酯类污染物,宽温设计支持-10℃~+60℃户外使用。

五、选型与使用注意事项

  1. 电流降额:实际应用建议正向电流控制在50~55mA(降额10%),延长产品寿命至5000小时以上;
  2. 散热要求:PCB板需预留散热焊盘,避免LED与其他发热元件近距离安装;
  3. 静电防护:生产过程需佩戴静电手环,使用防静电镊子/周转盒;
  4. 波长匹配:若用于UV固化,需确认胶水吸收峰与390~400nm区间重叠(如常用的丙烯酸类UV胶适配性良好);
  5. 反向电压限制:禁止施加超过5V的反向电压,防止LED反向击穿。

该产品以“小体积、高适配性”为核心优势,填补了小型近紫外应用场景的功率空白,适合对成本、体积敏感的终端设备设计。

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
