APA2106SURCK 产品概述

一、产品简介

APA2106SURCK 是 Kingbright 推出的高可靠性红色表面贴装(SMD)发光二极管。器件采用无色透明透镜,发光颜色为红色,体积小巧(封装约 2.1 × 1 mm),适用于各类指示、背光和状态显示场景。该型号在保持较高光强的同时具备宽视角和良好的环境适应性,便于在空间受限的电路板上进行密集布局与可靠焊接。

二、主要规格

  • 发光颜色:红色(Red)
  • 正向压降(Vf):典型 1.95 V(IF = 20 mA)
  • 正向电流(IF):20 mA(额定)
  • 功率:75 mW(器件额定/最大耗散,请以官方 datasheet 为准)
  • 峰值波长:645 nm;名义波长约 630 nm
  • 发光强度:80 mcd(典型值,IF = 20 mA)
  • 发光角度:120°
  • 透镜颜色:无色透明
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 封装形式:SMD,尺寸约 2.1 × 1 mm

三、光学与电气特性

APA2106SURCK 在 20 mA 驱动条件下具有较好的亮度与色致一致性。峰值波长 645 nm 意味着该器件的红光偏长波段,视觉上呈标准红色,发光强度约 80 mcd,适合做指示灯或近视距显示。120° 的大视角使其光分布均匀,不需要精密光学透镜即可获得良好可见性。典型正向压降为 1.95 V,驱动电路设计时可据此计算限流电阻。

四、封装与机械尺寸

器件为小型 SMD 封装(约 2.1 × 1 mm),适合自动贴片与回流焊流程。透明透镜有利于获得更好的发射角分布与光学稳定性。为保证焊接强度与热传导,建议在 PCB 设计时参照 Kingbright 官方数据手册提供的焊盘与焊膏模板尺寸进行布局,避免因焊盘过大或过小造成芯片应力或焊接缺陷。

五、热性能与工作环境

  • 建议按厂方温度-电流特性进行降额使用:在高温环境下(接近或超过 +85 ℃)应降低正向电流以延长寿命与稳定性。
  • 最大功率耗散标称 75 mW,实际功耗取决于 IF × Vf(在 20 mA、Vf ≈ 1.95 V 时器件自身功耗约 39 mW,低于额定耗散)。
  • 推荐采用良好散热的 PCB 设计,避免长期在高温下满载运行。

六、典型应用

  • 仪器与设备状态指示灯
  • 家电与消费电子的面板指示
  • 数码仪表与便携设备的指示/标识
  • 背光点阵或标识灯(点光源应用)
  • 工业控制面板、通信设备指示

七、使用建议与焊接注意事项

  • 焊接:建议采用无铅回流工艺并遵循 Kingbright 官方推荐的回流曲线及 JEDEC J-STD-020 标准,避免峰值温度超过器件规定值以防损伤。
  • 焊盘与贴装:按数据手册填写的焊盘尺寸与间距布局,确保焊点均匀,避免应力集中。
  • 静电防护:在取放与贴装过程中应采取 ESD 防护措施,防止静电损坏 LED 芯片。
  • 清洗:若需清洗,选用对 LED 无害的清洗剂并避免强烈机械冲击或过高温烘干。

八、示例电路与限流计算

使用单颗 LED 最常见的驱动方式为串联限流电阻。以 Vf = 1.95 V、目标 IF = 20 mA 为例:

  • 采用 5 V 电源:R = (5.0 − 1.95) / 0.02 ≈ 152.5 Ω → 选用标准阻值 150 Ω(实际电流约 20.3 mA)或 160 Ω(电流约 19.1 mA)。
  • 采用 3.3 V 电源:R = (3.3 − 1.95) / 0.02 ≈ 67.5 Ω → 选用 68 Ω。
  • 采用 12 V 电源:R = (12 − 1.95) / 0.02 ≈ 502.5 Ω → 选用 510 Ω(注意功耗和发热)。

若需更精确的亮度控制或多颗串联/并联配置,建议采用恒流驱动器或为并联 LED 提供独立限流电阻。

九、储存与可靠性

  • 储存建议:避免高湿、高温环境,密封防潮包装保存,防止透镜与封装受潮导致光学或焊接问题。
  • 使用寿命与可靠性与温度、驱动电流和工作环境密切相关。为获得长期稳定性,建议在额定电流下或适度降额使用,并遵循厂方推荐的老化与测试流程。

十、结论与采购建议

APA2106SURCK 以其小型化封装、较高亮度(80 mcd)与宽视角(120°)适用于多样的指示与显示场景。设计时应参照 Kingbright 官方 datasheet 获取精确的封装尺寸、焊盘建议与回流参数;在高温或连续点亮的应用中考虑降额驱动或采用恒流源以延长寿命。采购时请注意订购型号、最小包装单位与出货批次的可追溯性,以便进行可靠性验证与一致性测试。

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.
