EVERLIGHT 95-21SURC/S530-A3/TR7 产品概述

一、概述与主要规格

95-21SURC/S530-A3/TR7 是台湾亿光(EVERLIGHT)出品的一款贴片发光二极管(SMD-2 封装),封装尺寸约为 3.8 × 2 mm,采用无色透明透镜,发光颜色为红色,适用于高对比度指示、标识与点状照明场合。关键参数如下(典型/额定值):

  • 正向电流(If):20 mA(典型工作点)
  • 峰值波长(λp):632 nm;名义波长约 624 nm
  • 发光强度:600 mcd(在 20 mA 时)
  • 发光角度:25°(典型,窄角聚光型)
  • 正向压降(Vf):约 2.0 V(在 20 mA)
  • 最大功率耗散(Pd):60 mW(器件最大允许耗散)
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 透镜颜色:无色透明
  • 封装:SMD,尺寸 3.8 × 2 mm

二、光学与电气特性解读

  1. 发光波长与颜色
    虽然名义波长为 624 nm,但峰值波长 632 nm 表明该器件在红色光谱的低波长偏移范围内具有较强的光谱输出,视觉上呈标准红色。该波段对可见度与对比度表现良好,适用于状态指示。

  2. 发光角度与应用效果
    25° 的窄光束角意味着光能高度集中,适合需要点状、高亮度指示或远距离可视性的应用。对于背光或大面积指示,应注意视角受限带来的可见范围缩小。

  3. 电气驱动与功耗
    在推荐的 If = 20 mA 下,正向压降约 2.0 V,电气输入功率约为 40 mW(Vf × If)。标称的 60 mW 常用于表示器件的最大耗散能力(Pd),设计时应保证实际耗散低于该值以免热量累积影响寿命与可靠性。

三、典型应用场景

  • 工业设备面板与状态指示灯(要求高亮度、窄角可视)
  • 精密仪表、医疗设备的指示灯
  • 通信与网络设备中的状态/故障指示
  • 仪表盘与便携设备的定点信号指示

四、驱动建议与电路注意事项

  1. 电流限制
    推荐在设计中使用限流电阻或恒流驱动器,以将 If 控制在 ≤20 mA。若需延长寿命或降低热升,常见做法是使用 10–15 mA 的工作电流。

  2. 串联电阻计算
    可用公式 R = (VCC − Vf) / If 计算串联电阻;计算结果取最接近标准阻值并考虑功率余量。举例:若 VCC = 5 V,If = 20 mA,Vf = 2.0 V,则 R ≈ (5 − 2) / 0.02 = 150 Ω。

  3. 脉冲驱动
    脉冲驱动可在短时间内提高峰值亮度,但须保证占空比与平均功率使长期耗散不超出最大 Pd。脉冲驱动时注意电流峰值不得超过器件极限且需评估热应力。

五、装配与可靠性提示

  • 焊接:建议遵循常规 SMD 回流焊工艺,控制峰值温度与时间,避免超出器件的焊接温度限制(参考厂商回流曲线)。
  • ESD 防护:发光二极管对静电敏感,装配与测试时应采取防静电措施(接地、腕带、工作台防护等)。
  • 热管理:尽管单颗 LED 功耗不高,但在密集布置或高环境温度下需注意热量累积,适当降低工作电流或增加热散设计。
  • 存储:避免在高温高湿环境长期存放,装贴前遵循干燥储存与回潮控制建议。

六、封装与焊盘建议

95-21SURC/S530-A3/TR7 采用 SMD 迷你封装(3.8 × 2 mm),无色透明透镜对视觉方向要求较高。实际 PCB 布局时建议:

  • 按厂商推荐的 PCB 焊盘尺寸设计焊盘并保留良好的焊膏印刷规则;
  • 保证焊点成形良好以获得稳定的热与电接触;
  • 标注极性(阳极/阴极)以便正确贴装。

七、结论

95-21SURC/S530-A3/TR7 是一款窄角高亮度的红色 SMD LED,适合需要集中光束与明确视觉指示的应用。设计时应遵循推荐的驱动电流、热管理与防静电措施,以确保长期稳定性与可靠性。如需更详细的机械图、回流焊曲线或光谱分布曲线,建议参考 EVERLIGHT 官方数据手册或联系供应商获取完整资料。

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.
