IR204C-A 红外发光二极管（EVERLIGHT）产品概述
一、产品简介
IR204C-A 是台湾 EVERLIGHT（亿光）推出的一款高可靠性红外发光二极管，采用直插式 φ3mm 封装，适用于各种需要近红外光源的电子与光电应用。器件以 940nm 波长发射为主，人眼不可见但对常见硅光电器件有良好响应，便于与红外接收器、光电二极管、摄像模组配合使用。
二、主要参数
- 峰值波长（λp）：940 nm（近红外）
- 正向压降（Vf）：典型 1.2 V（测试条件：If = 20 mA）
- 辐射强度：典型 4 mW/sr（If = 20 mA）
- 推荐工作电流：20 mA（用于标称光强测量）
- 工作温度：-40 °C ～ +85 °C
- 封装类型：插件（直插），灯珠直径 D = 3 mm（T‑1）
以上为典型参考条件，具体极限值与电气/光学曲线请参见厂家数据表。
三、光电特性与使用要点
IR204C-A 在 20 mA 条件下能提供约 4 mW/sr 的辐射强度，正向压降约为 1.2 V。由于 LED 的光输出随电流与温度呈非线性关系，实际应用中应使用恒流驱动或串联限流电阻以保证稳定发光。限流电阻的计算公式为： R = (V_supply - Vf) / If 例如在 5 V 供电且 If = 20 mA 时，R ≈ (5 − 1.2) / 0.02 ≈ 190 Ω（仅示例，实际设计应考虑容差与温升）。
对于需要更高瞬时光强的场景，可采用脉冲驱动，但必须遵守器件的脉冲宽度与峰值电流限制以避免损伤。热管理方面，尽量避免长时间过流及在高温环境下连续满功率运行，以延长寿命并保持光输出稳定。
四、典型应用场景
- 红外遥控与红外通信链路
- 接近/距离传感与防撞检测（与接收端配合）
- 光电编码器、位置与转速检测
- 夜视补光（短距离、非可见光照明）
- 工业自动化中的光电开关和液位检测
该器件对标准硅光电探测器、接收模块和成像传感器具有良好匹配，适合大多数消费与工业级光学系统。
五、封装与安装建议
IR204C-A 为直插式 φ3mm 环氧封装，便于手工焊接与自动插装。安装与焊接时建议：
- 遵循制造商焊接工艺，避免长时间高温暴露；
- 焊接后避免在未确定冷却前弯折引脚；
- 在多灯并联或密集封装时预留足够散热空间；
- 防静电处理（ESD）并避免逆向电压冲击。
六、选型提示与注意事项
在选型时关注实际工作电流、光束角、接收器灵敏度与系统所需的光功率/指向性。940 nm 波长对某些摄像传感器仍有可见响应，如需完全“不可见”或更窄谱段输出，应与接收端匹配或考虑带通滤光片。最终设计应以厂家完整数据表为准，必要时进行样品测试以验证在目标环境下的性能与可靠性。
总之，IR204C-A 以其稳定的近红外输出、通用的 3mm 插件封装和宽温度范围，适合大量常见的红外发射应用，是工程设计中常用且性价比高的元件选择。

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.
