XL-2012HIRC-850 0805封装红外发射二极管产品概述

一、产品基本定位与核心特性

XL-2012HIRC-850是成兴光(Xinglight) 推出的一款0805贴片式近红外发射二极管,核心波长为850nm(人眼不可见区域),主打小型化、低功耗、宽视角 三大特性,适配各类对体积敏感、需隐蔽红外发射的应用场景。作为贴片器件,其兼容自动化贴装工艺,可有效节省PCB布局空间,是替代传统插件红外管的高性价比选择。

二、关键性能参数解析

该器件的核心参数直接决定了其应用边界,具体解析如下:

  1. 波长850nm:处于近红外光谱区域,人眼无可见红光,隐蔽性强;同时与多数红外接收器件(如PIN光电二极管、CMOS图像传感器)的响应峰值匹配,信号传输效率高。
  2. 辐射强度2mW/sr:满足1-5米近距离感应/补光需求,平衡了发射亮度与功耗,避免因过高辐射强度导致的额外散热问题。
  3. 正向压降(Vf)1V~1.7V:典型值约1.2V,适配3.3V/5V常见MCU I/O口驱动(无需额外升压/降压电路),简化电路设计。
  4. 耗散功率(Pd)55mW:额定功率上限,使用时需确保正向电流(If)不超30mA(直流),否则易导致器件过热损坏。
  5. 视角120°:宽辐射角度,可覆盖较大范围空间,适合楼道人体感应、安防补光等需广域覆盖的场景。
  6. 反向耐压(Vr)5V:反向电压不得超过此值,否则可能引发反向击穿,需注意电路反向保护。
  7. 工作温度-40℃~+85℃:宽温范围,可适应户外(如安防摄像头)、工业(如流水线感应)等高低温环境。

三、封装与典型应用场景

3.1 封装特点

虽官方未明确封装细节,但结合型号中“0805”标注,其封装尺寸为2.0mm×1.2mm(贴片封装标准尺寸),采用SMD(表面贴装)结构,具备以下优势:

  • 支持自动化贴装,生产效率高;
  • 体积小,适合智能手环、小型遥控器等紧凑设备;
  • 抗振动性能优于插件器件,适配移动设备(如车载红外传感器)。

3.2 典型应用

  1. 智能家居:红外人体感应模块(楼道自动灯、智能门锁触发);
  2. 安防监控:夜视摄像头红外补光(隐蔽不干扰夜间拍摄,且不暴露设备位置);
  3. 消费电子:小型红外遥控器(如机顶盒、智能家电遥控器);
  4. 工业控制:近距离物体感应(流水线计数、传送带位置检测);
  5. 医疗设备:小型红外触发装置(如便携血氧仪辅助感应)。

四、可靠性与环境适应性

  1. 宽温稳定性:-40℃~+85℃的工作温度范围,可满足户外(如冬季低温、夏季高温)、工业车间等极端环境需求;
  2. 抗静电能力:符合行业常规ESD防护标准(典型值±2kV,需注意生产过程中静电防护);
  3. 存储条件:建议存储于-55℃~+125℃、湿度≤60%的环境中,避免长期暴露于潮湿、高温环境导致性能衰减。

五、选型与使用注意事项

  1. 驱动电路设计:需串联限流电阻,计算公式为:
    ( R = \frac{V_{cc} - V_f}{I_{f_max}} )
    例:若Vcc=3.3V、Vf=1.2V、If_max=30mA,则R≈70Ω(选75Ω标准电阻即可);
  2. 电流限制:直流正向电流不得超过30mA,脉冲电流可适当提高(但平均功率需≤55mW);
  3. 静电防护:生产、测试过程中需佩戴防静电手环,使用防静电工作台,避免器件因静电损坏;
  4. 反向保护:若电路存在反向电压,需并联二极管(如1N4148)进行反向钳位,防止器件击穿。

该器件凭借小型化、低功耗、宽温适应性等优势,在智能家居、安防、消费电子等领域具备广泛应用潜力,是中小批量产品选型的实用之选。

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.
