WS2815B-V1-4P 产品概述
一、产品简介
WS2815B-V1-4P 是 worldsemi 推出的 SMD5050-4P 型 12V 幻彩三色灯珠，集成驱动与颜色控制电路，单颗工作电流典型 12mA，静态电流仅 2mA。灯珠尺寸 5.0×5.0×1.57mm，四脚设计（VCC、GND、DIN、DOUT），支持断点续传，适配灯条、氛围灯、指示灯、充电桩、机器人及小家电等场景。
二、主要参数
- 工作电压：9.5V ～ 13.5V（典型 12V）
- 数据速率：800 kbit/s
- PWM 频率：4 kHz
- 发光波长：B 465–475 nm；G 510–520 nm；R 620–630 nm
- 发光强度（单色）：B 190 mcd；R 310 mcd；G 800 mcd
- 静态电流：2 mA；工作电流：12 mA（典型）
- 工作温度：-40 ℃ ～ +65 ℃
- 外形尺寸：5.0 × 5.0 × 1.57 mm
- 封装：SMD5050-4P，品牌：worldsemi
三、功能与优势
- 内置驱动芯片，单颗可直接接入 12V 总线，简化布线与控制逻辑；
- 断点续传功能：断电或数据中断后恢复供电可继续之前动画，提升灯带可靠性；
- 4kHz PWM 与 800 kbit/s 数据率可实现平滑渐变与快速颜色更新；
- 高亮绿色、良好红蓝饱和度，适配多种色彩表现需求；
- 小尺寸、高集成度，便于 SMD 自动贴装和紧凑布局。
四、典型应用场景
- LED 灯条与模组、氛围照明与背光；
- 指示灯与信号提示（充电桩、控制面板）；
- 服务机器人、扫地机及智能家电的状态显示；
- 装饰和舞台灯光的像素化控制方案。
五、引脚定义与典型连接建议
- 引脚：VCC（12V）、GND、DIN（数据输入）、DOUT（数据输出）。
- 典型连接建议：VCC 与 GND 旁并联去耦电容（建议 100µF/16V），数据线串联 300–500Ω 抑制反射，控制器信号与灯珠共地；若控制器逻辑电平不同，建议使用电平转换器以保证可靠通信。布线时注意减少长线干扰并在每段适当加电源补偿。
六、封装与可靠性建议
- SMD5050-4P 封装适合回流焊工艺，推荐按元件供应商回流曲线进行焊接；
- 使用与存储中注意防潮防静电，避免长时间高温或潮湿环境；
- 通电运行时保持散热空间，避免长期高温影响色彩稳定性与寿命。
七、采购与使用注意
- 型号：WS2815B-V1-4P，品牌 worldsemi；
- 采购时确认电压规格与断点续传功能符合应用需求，批次间如对颜色一致性有严格要求建议索取色谱报告或样品验证；
- 设计时预留电源裕量并做好 EMI/ESD 防护，确保整机长期稳定运行。

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.
