NTD3528R2 产品概述
一、产品简介
NTD3528R2 为国星光电（NationStar）推出的高亮红色 LED，采用 SMD2835 贴片封装，属于正贴（Top Mount）独立二极管设计。器件以窄发光角度和高照度为特色，适合需点光源或定向照明的场合。
二、关键参数
- 发光颜色：红色
- 峰值波长：670 nm；波长范围：650 nm ~ 670 nm
- 正向电压 (Vf)：2.0 V ~ 2.7 V
- 额定正向电流 (If)：100 mA（最大/脉冲条件）
- 发光强度：4000 mcd ~ 8000 mcd
- 发光角度：30°
- 二极管配置：独立二极管
- 封装：SMD2835；载带方式：正贴
- 工作温度范围：-40 ℃ ~ +100 ℃
三、电气与光学特性说明
在 100 mA 驱动下，器件功耗约为 0.2 W ~ 0.27 W（Vf × If）。峰值光谱集中在 670 nm 附近，给予视觉上标准的高饱和红色表现。30° 的窄发散角使得光束更聚焦，适合点状照明、指示与光学耦合应用。
四、热设计与驱动建议
为保证长期可靠性，建议连续工作时将驱动电流控制在 60–80 mA 区间，如需短脉冲可采用 100 mA 峰值（需保证占空比和温升受控）。注意器件热阻有限，需设计良好器板散热路径（加铜箔、热过孔或散热片），以降低结温并维持光输出稳定。
五、封装与可靠性
SMD2835 封装兼容常见 SMT 贴装流程，建议按厂家回流焊温度曲线进行焊接（遵循 260 ℃ 峰值短时加热原则）。器件适应宽温工作环境（-40 ℃ 至 +100 ℃），适用于室温与严苛环境下的长时间工作，但建议避免长期在最高温度下满载运行以延长寿命。
六、典型应用场景
适用于汽车指示灯、仪表盘背光、工业指示灯、信号指示、舞台/装饰小功率点光源、光学传感器光源与小型标识牌等需要高亮聚光红光的场合。
七、焊接与安装建议
- 推荐合理的 PCB 铜箔面积与热过孔以提高散热效率；
- 使用与焊盘尺寸相匹配的焊膏量，避免过量焊料导致热阻增大；
- 贴装后建议进行常温到高温的回流焊，并严格控制回流曲线以保护封装与内部键合线。
如需器件的详细电光曲线、热阻数据或样品与大包装信息（卷带/盘装、每盘数量等），建议联系国星光电或供应商索取完整数据手册与出货规格表。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
