PD15-21C/TR8 产品概述 — EVERLIGHT(台湾亿光)PIN 光电二极管

一、产品简介

PD15-21C/TR8 是 EVERLIGHT(亿光)推出的一款 PIN 结构芯片型光电二极管,封装为 1206 贴片型(2‑Pin SMD),采用带卷盘(TR)包装,便于 SMT 量产贴装。器件对近红外光具有良好响应,标称峰值波长约 980 nm,光谱响应范围宽(约 400 nm 至 1200 nm),暗电流小(典型 10 nA),抗反向电压能力强(直流反向耐压 Vr = 32 V),工作温度范围为 ‑25 ℃ 至 +85 ℃,适合多种商用与工业级光电检测场合。

二、主要特点

  • PIN 结构,响应速度较 PN 型光电二极管更快,适合脉冲与高速信号检测
  • 光谱响应宽,峰值位于近红外区(~980 nm),对 940 nm 波段光源(常见于遥控、通信与生物传感)有良好灵敏度
  • 低暗电流(10 nA 等级),可在低光照条件下维持较好的信噪比
  • 直流反向耐压 32 V,器件耐压裕度大,便于在反向偏压下提升响应速度与线性范围
  • 1206 SMD 封装,便于自动贴装与空间受限的应用场景
  • 宽工作温度(‑25℃ ~ +85℃),适用于一般工业与消费电子环境

三、典型应用

  • 红外接收与遥控信号接收(940 nm 红外 LED 配套)
  • 接近/距离传感、断点检测、光电开关
  • 光纤入射端或自由空间红外检测(需滤光或透镜时)
  • 工业自动化中的脉冲/条码/编码器光电检测
  • 医疗/生命体征传感(如与 940 nm 光源配合的脉搏血氧传感前端探测)——需根据系统要求做光学与电气确认

四、使用建议与电路集成

  • 偏置方式:器件允许最大反向电压 32 V。常见设计中,为平衡响应速度与噪声,通常采用小至中等反向偏压(视系统需求而定)。
  • 前端电路:推荐使用跨阻放大器(TIA)进行电流到电压的转换,选择适当反馈电阻以兼顾带宽与灵敏度;并在电路中加入并联电容或滤波以抑制高频噪声与寄生振荡。
  • 光学耦合:根据应用可选配透镜、光束整形或窄带滤光片,提高光收集效率和抗干扰能力。
  • 封装与方向:1206 芯片封装,应注意极性标识与贴装方向,保证光学窗口对准光源。

五、可靠性与处理注意事项

  • ESD 保护:光电二极管对静电敏感,制造和测试过程中应采取 ESD 防护措施(佩戴防静电手环、使用接地工作台、储存于导电包装中)。
  • 焊接建议:使用符合制造商推荐的回流焊曲线与工艺,避免过热或长时间高温暴露;若需手工焊接,尽量缩短加热时间并控制温度。
  • 贮存条件:建议干燥、防潮、常温保存;长期储存请参照厂商包装和湿敏等级要求。
  • 机械应力:避免在封装基板上施加过大弯折或挤压力,防止焊盘或内部线键损伤。

六、封装与订购信息

  • 封装:1206 SMD 芯片,2‑Pin
  • 包装:TR(Tape & Reel)规格,适合自动化贴片生产
  • 型号:PD15-21C/TR8(品牌:EVERLIGHT / 台湾亿光)
    如需批量采购或获取详细器件数据手册(含典型曲线、引脚定义、回流焊曲线与完整电气特性),建议联系 EVERLIGHT 官方或授权代理以获得最新规格说明书与可靠性报告。

总结:PD15-21C/TR8 以其宽谱响应、低暗电流和较高耐压特性,适合多种近红外检测场景。合理的偏置与前端设计、严格的 ESD 管理与合规的焊接工艺,将帮助发挥该器件在速度、灵敏度与稳定性方面的优势。

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
