ALS-PDIC144-6C/L378 产品概述

一、主要参数

ALS-PDIC144-6C/L378 为 EVERLIGHT(亿光)系列的光学量环境光传感器(Ambient Light Sensor),封装为传统插件型 3mm T-1(D=3mm)。基础工作参数如下:

  • 工作温度:-40℃ ~ +85℃
  • 感测类型:光强(环境光)
  • 工作电压:1.8V ~ 5.5V
  • 封装形式:插件式,两引脚,便于穿孔安装和更换

二、产品特点

  • 小型化 3mm 封装,适合空间受限的面板或设备开口安装。
  • 宽工作电压范围,兼容 1.8V 至 5.5V 的多种低压系统(MCU、PMIC)。
  • 宽温区适用,适合室内外和工业级环境。
  • 响应环境光强变化迅速,便于用作屏幕背光与照度检测的前端传感元件。

三、工作原理与使用方式

该器件为光敏元件,受照光强度变化时会产生与光强成比例的电流输出。一般以两端引脚接入电路:

  • 直接配合电阻转换为电压进行简单读出;
  • 或使用跨阻放大器(TIA)将光电流精确转换为电压,以获得更高线性度和灵敏度。 在设计时常需根据目标响应速度与灵敏度选择适当负载阻值或放大器带宽。

四、典型应用场景

  • 手机、平板与笔记本等显示器自动背光调节
  • 智能家居与物联网终端的环境光检测
  • 摄像头曝光补偿与光学触发
  • 室内照明与节能控制系统
  • 仪器仪表与工业设备的光照监测

五、设计与装配建议

  • 安装时注意光轴方向,避免遮挡或不必要的漫反射影响读数。
  • 若对抗干扰性要求高,建议在传感器与电源之间加入去耦电容,并在信号通路加低通滤波降噪。
  • 大动态范围需求时采用跨阻放大电路;简单场合可用固定电阻后由 MCU ADC 采样。
  • 插件式焊接和机械固定方便维修,但请遵循厂商的焊接工艺与最高温度要求以保证可靠性。

六、注意事项

  • 避免长期直射强光(如激光)照射以防器件损伤或参数漂移。
  • 工作环境应防止凝露、强腐蚀性气体及严重机械振动。
  • 出厂及存储期内遵守防静电、防潮措施;实际设计请参考原厂完整数据手册以获得精确电气与光学参数。

总体而言,ALS-PDIC144-6C/L378 以其小巧的 3mm 插件封装、宽电压与温度适应性,适合用于需要稳健环境光检测的消费与工业电子设备中。

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.

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.

Replenishment inquiry Typical RFQ workflow
