XL-3528IR-T202(3528贴片红外LED)产品概述

一、产品简介

XL-3528IR-T202 是成兴光(Xinglight)推出的一款 SMD3528 封装红外发光二极管,工作波长覆盖 925nm~955nm(典型附近为940nm),半波宽约 35nm。小型表贴设计便于自动贴装,适合安防照明、夜视补光、红外感应与通信等多种场景。

二、主要规格

  • 封装:SMD3528(3.5 × 2.8 mm)
  • 波长:925nm ~ 955nm
  • 半波宽(FWHM):35nm
  • 正向压降(Vf):1.3V ~ 1.4V
  • 耗散功率(Pd):150mW(器件耗散极限)
  • 正向电流(If,峰值/直流说明):100mA(按提供参数为参考最大值,应注意热管理与降额)
  • 辐射强度:15mW/sr;5mW/sr(不同出货等级或测量条件下的代表值)
  • 视角:125°(宽视角,适合大范围均匀照明)
  • 直流反向耐压(Vr):5V(避免反向高压)
  • 工作温度:-40℃ ~ +85℃
  • 品牌:Xinglight(成兴光)

三、光电与热管理要点

按照标称参数,若取 Vf ≈1.35V、If =100mA,则器件功耗约 135mW,接近额定耗散功率 150mW。实际应用中建议:

  • 优先采用恒流驱动,避免短路或过冲电流;
  • 对长期连续工作场合进行降额设计(控制工作电流或采用 PWM 驱动并限制平均功率);
  • 增加 PCB 铜箔面积和散热铺铜,必要时与系统散热结构结合,确保结温和环境温度在安全范围内。

四、典型应用

  • 夜视/安防红外补光灯与摄像头夜间照明
  • 红外入侵/人体/光电传感器光源
  • 遥控/短距红外通信(需配合合适调制)
  • 人机识别/指纹与面部识别的不可见照明
  • 汽车/工业自动化中近红外感测场合

五、封装与装配建议

  • 推荐遵循标准 SMD 回流焊工艺,控制峰值温度和加热时间以保护器件;
  • 避免长时间高温回流或重复回流,出厂后按湿敏等级储存并在规定时间内贴装;
  • 贴装时注意极性标识,防止反向击穿(Vr ≤ 5V);
  • 防静电(ESD)措施及清洁无腐蚀性助焊剂以延长可靠性。

六、使用注意与电路建议

  • 若驱动电源电压高于 Vf,建议使用恒流源或串联限流电阻:R = (Vdrive − Vf) / If(仅作计算示例);
  • 防止电源瞬态导致反向电压或过流,可在必要处加反向保护二极管或限流电路;
  • 对于要求高均匀度的照明系统,可采用配光透镜或多点布局以利用其 125° 宽视角特性。

七、可靠性与测试建议

为保证长期性能,建议在样品阶段进行寿命与老化测试(不同温度与驱动条件下的光输出衰减),并根据测试结果调整工作电流与散热设计。

总结:XL-3528IR-T202 以其窄波段近红外谱线、较高辐射强度与通用的 SMD3528 封装,适用于多种不可见光照明和感测场景。合理的恒流驱动与热管理是发挥其性能与延长寿命的关键。若需更详细的电气特性曲线或封装尺寸图,可提供给您进一步资料。

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
