WS3570 产品概述
一、产品简介
WS3570 是 worldsemi 面向汽车照明的高功率 SMD 灯珠，采用倒装芯片工艺（flip‑chip），单颗功率 30W，发光颜色为冷白（色温 6200K～6700K）。封装尺寸为 7×3.5 mm，二极管配置为共阳极，提供雾状黄色与雾状白色两种透镜选择，光束角约 120°，适用于多种车用照明场景。
二、主要特性
- 功率：30W（单颗）
- 正向电流：1.2A（额定）
- 正向压降（Vf）：8.5V ～ 10V（在额定电流下）
- 色温：6200K～6700K（冷白）
- 发光角度：120°
- 工作温度：-30℃ ～ +125℃
- 封装：SMD，7×3.5 mm；倒装芯片，良好热路径
- 二极管配置：共阳极；透镜：雾状黄色 / 雾状白色
三、典型应用
- 汽车外部照明：日间行车灯、近光/远光补助光源（视系统设计）
- 汽车内部及装饰照明
- 信号灯、转向灯、位置灯与标识灯（marker）
- 其他需要高显色性与稳定冷白光的车载照明场景
四、电气与光学建议
- 使用恒流驱动器驱动，额定电流 1.2A；驱动器须能覆盖 8.5V～10V 输出范围并具备过流保护。
- 为保证光通与寿命，设计中应考虑热降额，随结温升高适当降低电流。
- 建议在电源与灯珠间加入反向保护与浪涌抑制电路以应对汽车电气扰动。
五、热管理与可靠性
- 倒装芯片结构利于热量直接传导至焊盘，要求 PCB 采用散热铜泊或金属基板并做好热过孔布局。
- 在高温条件（接近 +125℃）下应评估光衰与色温漂移，必要时增加散热片或强制风冷。
六、封装与组装建议
- 封装为 SMD，推荐采用常规回流焊工艺进行贴装，遵循制造商的回流曲线与焊膏规范。
- 装配时注意 ESD 防护与静电敏感元件处理，避免反接与瞬态电压损伤。
七、测试与质量保证
- 在量产前进行热循环、振动、盐雾与高低温老化测试，确保满足车规环境下的长期可靠性。
- 建议针对整车应用做 EMC 与电磁抗扰度验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
