NPD3535I6 为国星光电(NationStar)推出的高辐射强度近红外发光二极管,采用常见的 3535 封装,发射波长覆盖 940nm~970nm,半波宽约 50nm。该器件提供多个辐射强度等级(典型值 65 mW/sr 与 150 mW/sr),视角宽达 120°,适合广泛的红外照明与传感应用。
按照器件给定参数,务必注意功耗与热管理:当 If=350mA 且 Vf 在 1.3~2.0V 时,电耗约为 0.455W ~ 0.7W,已超过封装 Pd=380mW 的连续耗散能力。因此:
3535 SMD 封装,适合自动贴装与回流焊工艺。封装对光学指向性有较好控制,推荐按国星光电提供的封装图纸设计 PCB 贴装孔位与焊盘,并遵循标准回流曲线以保证焊接可靠性。
NPD3535I6 是一款面向红外照明与传感的高强度 3535 封装 LED,波长范围适合大多数近红外成像与传感应用。其高辐射强度选项与宽视角使得系统设计灵活,但须重点关注功耗与热设计,必要时采用脉冲驱动以发挥 350mA 峰值性能并确保长期可靠性。若需更详细的电学曲线、脉冲条件或封装图纸,建议参考国星光电的完整数据手册或直接向厂商咨询。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
