ASMT-YTB2-0BB02 产品概述

一、产品简介

ASMT-YTB2-0BB02 为 Broadcom(博通)出品的高可靠性 RGB SMD 发光二极管,封装为 6-SMD、J 引线形式,采用无色透明透镜,三色发光芯片为独立二极管设计。器件体积小(3.4 × 2.8 × 1.8 mm),光学分布宽阔(发光角度 120°),适用于指示灯、状态显示、背光、信号提示及小型全彩点阵等应用场景。

二、主要电气与光学参数

  • 二极管配置:独立二极管(R/G/B 分离驱动)
  • 波长范围:
    • R:618 nm ~ 628 nm(峰值 629 nm)
    • G:525 nm ~ 537 nm(标称峰值 521 nm,见数据表差异时以出厂数据为准)
    • B:465 nm ~ 477 nm(峰值 464 nm)
  • 正向电流(If):R/B/G 均为 20 mA(典型工作电流)
  • 正向压降(Vf):
    • R:1.80 V ~ 2.50 V
    • G:2.80 V ~ 3.80 V
    • B:2.80 V ~ 3.80 V
  • 输出功率(参考):R: 125 mW;G: 114 mW;B: 114 mW(注:此为厂方给定功率指标,光输出或电光效率受工艺与测试条件影响,应以实际测量为准)
  • 发光角度:120°(广角分布,易于获得均匀视角)
  • 透镜:无色透明(无色差着色透镜)

三、机械尺寸与环境特性

  • 外型尺寸:长 3.4 mm × 宽 2.8 mm × 高 1.8 mm
  • 封装形式:6-SMD,J 引线(适配常见表面贴装 PCB 布局)
  • 工作温度范围:-40 ℃ ~ +110 ℃(适应宽温区工业环境)
  • 包装与出厂分档:建议依据 Broadcom 正式数据表确认色彩、亮度分档(Bin)和包装方式,以便实现批次一致性与色彩匹配。

四、典型应用场景

  • 面板及设备状态指示(休眠/工作/故障等)
  • 仪器仪表和消费电子的按键背光与图标照明
  • 指示灯条、信号灯、指示柱阵列及小型点阵显示单元
  • 需要宽视角、颜色可控的应用场合

五、设计与驱动建议

  • 驱动方式:建议使用恒流源或在每路串联限流电阻进行恒流控制,工作电流以 20 mA 为基准,必要时按热管理与亮度需求进行降额。
  • PWM 调光:支持 PWM 调光以实现色彩混合与亮度控制,PWM 频率应高于人眼可感知频率以避免可见闪烁。
  • 电源与布局:三色独立,需为 R/G/B 各提供独立驱动通道并考虑走线与阻抗匹配,避免串扰。
  • 色彩校准:批次间存在色温与波长漂移,建议在系统层面做软件校准或选择同一 Bin 的器件用于颜色一致性要求高的场合。

六、可靠性与封装焊接注意事项

  • 焊接:遵循无铅回流焊工艺规范进行焊接,避免超温滥时(推荐参照 Broadcom 官方回流曲线,典型峰值温度 ≤ 260 ℃ 且高温持续时间短)。
  • 热管理:虽然单颗功耗不高,但在密集排列或长时间高电流工作时需考虑 PCB 散热(增加铜箔面积或散热通道)。
  • ESD 与湿热:出厂后注意防静电保护与防潮封装管理,存储与贴装过程中遵守器件的 MSL 要求。
  • 可靠性验证:建议在设计验证阶段进行热循环、寿命、振动与湿热测试,以确认在目标应用环境下的表现。

七、选型与测试建议

选型时以 Broadcom 正式数据表为准,关注色彩分档(bin)、亮度/输出功率测试条件、正向压降典型值与最大额定值。样片评估阶段,应在预定工作电流、PCB 板材与散热条件下进行光电特性测量(光谱、光通量/光功率、Vf、色坐标)与长期可靠性测试,确保达到系统级要求。

总结:ASMT-YTB2-0BB02 属于封装紧凑、视角宽、三色独立驱动的高可靠 RGB SMD 器件,适合多种需要可控彩色指示与背光的应用。最终设计应结合厂方数据表与样片测试结果进行详细确认。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
