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):
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。
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。
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。
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。
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。
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。
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:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
