EVERLIGHT HIR42-21C/L289/TR8 红外发射管产品概述
一、产品简介
HIR42-21C/L289/TR8 是台湾亿光（EVERLIGHT）推出的一款小尺寸表面贴装红外发射二极管，封装尺寸仅 2.2 × 1.8 mm，中心波长 850 nm，适用于各种近距离红外发射与检测应用。该器件在 20 mA 驱动条件下具有较高的辐射强度，兼顾小体积与良好的光输出效率，适合对体积、成本和可靠性有要求的消费类与工业类产品。
二、主要参数
- 波长：850 nm
- 正向压降 Vf（典型）：1.4 V
- 辐射强度（典型）：11 mW/sr @ 20 mA
- 额定正向电流 If（最大）：65 mA
- 直流反向耐压 Vr（最大）：5 V
- 耗散功率 Pd：130 mW
- 工作温度范围：-25 ℃ ~ +85 ℃
- 封装形式：SMD，2.2 × 1.8 mm
- 品牌：EVERLIGHT（亿光）
三、主要特点
- 小尺寸 SMD 封装，适合高密度贴片组装及自动化生产。
- 在 20 mA 条件下提供 11 mW/sr 的较高辐射强度，发射效率高。
- 低正向压降（约 1.4 V），降低驱动功耗与电路复杂度。
- 容许较宽的工作温度范围，适应一般消费与工业温度环境。
四、典型应用
- 红外遥控与红外通信链路
- 接近/接收器件配合（遥测、障碍检测、位置检测）
- 光电开关、对射/漫反射检测系统
- 夜视/可见光摄像外补红外照明（短距）
- 智能家电、安防与自动化终端等小型化设备
五、使用建议与注意事项
- 驱动与限流：典型测量在 20 mA 下辐射强度为 11 mW/sr，实际应用可按所需亮度与寿命要求选择驱动电流，务必使用限流电阻或恒流驱动以防过流；若采用 65 mA 为最大额定值，仅在短时或经厂商确认的脉冲条件下使用。
- 反向耐压：Vr 最大 5 V，禁止在工作中施以超过该值的反向电压。
- 热设计：Pd 为 130 mW，应关注器件的热阻与PCB散热，长期高电流会加速衰减，建议在靠近散热良好的铜箔区域布局。
- 贴装与焊接：作为 SMD 器件，推荐采用标准回流工艺，遵循厂商焊接温度曲线并避免过热以保证封装与光学特性。
- 防静电与保管：出厂贴带包装时注意防静电处理，储存和使用过程中避免强光、潮湿和静电冲击。
六、选型参考
选择时根据所需辐射强度、工作距离与环境温度确定典型驱动电流；若需更远距离或更高强度，可选择更大功率或封装带透镜的红外发射器，并注意匹配接收器的灵敏度与角度覆盖。
如需详细电气特性曲线、典型光学角度或封装图纸，请参考 EVERLIGHT 官方数据手册或联系供应商以获取完整规格与应用文件。

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.
