NTD3528G1 产品概述
一、产品简介
NTD3528G1 为国星光电出品的绿色高亮贴片发光二极管（SMD），封装尺寸为 3528（3.5 × 2.8 mm），单颗独立二极管正贴封装。设计用于中高亮度照明与指示场合，峰值波长 525 nm，视觉呈绿色，视角宽广，适配多种表面贴装自动化生产线。
二、主要电光参数
- 发光颜色：绿色
- 峰值波长：525 nm（波长范围 515–525 nm）
- 正向电流：200 mA（额定）
- 正向压降 Vf：2.6–3.6 V
- 发光强度：15000 mcd（额定条件下）
- 发光角度：125°
- 工作温度范围：-30 ℃ ~ +85 ℃
- 二极管配置：独立二极管（单体）
- 封装形式：3528 正贴（SMT）
三、性能亮点
- 高亮度：在额定电流下光强达到 15000 mcd，适合需高可视性的指示和背光应用。
- 宽视角：125° 的发光角度有利于均匀照明和较大视区覆盖。
- 宽工作温度：-30 ℃ 到 +85 ℃，适应室内外环境温度变化。
- 标准 SMD 封装：兼容常规贴装设备与自动化生产流程。
四、驱动与热管理建议
- 驱动方式：建议使用恒流驱动源，避免直接恒压驱动；为保护 LED，应在驱动回路中采用限流电阻或恒流源。
- 功率估算：最大耗散约为 P = Vf × If，按 Vf 最大 3.6 V、If 200 mA 计算，约 0.72 W，热量不可忽视。
- 散热措施：3528 封装体积小，长期高电流工作必须优化 PCB 铜厚、增加散热铜箔或散热垫，并考虑并联多条电源轨分摊热流。高温环境下建议对工作电流进行降额。
五、封装与焊接说明
- 贴装方式：正贴 SMT，推荐标准 3528 PCB 焊盘布局并留足热流通道。
- 回流焊：遵循通用无铅回流曲线，控制峰值温度与保温时间，避免重复高温循环。
- ESD 与搬运：属于静电敏感器件，操作及包装需采取防静电措施（工作环境接地、佩戴防静电手环等）。
六、典型应用场景
- 城市/商业标识与导视系统
- 汽车仪表和指示灯（需按车规化考量）
- 工业控制面板与设备指示
- 背光、装饰照明与便携式设备指示
七、可靠性与注意事项
- 建议在实际应用中进行寿命评估与热测试，按照环境温度对电流进行适当降额以延长使用寿命。
- 避免在超过规格的温度或湿度条件下长期工作；存储时应保持干燥、避光、防潮。
- 在并联使用多颗 LED 时应保证每颗均有稳定恒流或良好分流措施，防止因个体差异导致热失控。

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.
