PT26-61B/TR8 产品概述
一、产品概述
PT26-61B/TR8 是台湾亿光（EVERLIGHT）推出的一款小型 SMD 光电晶体管，采用 NPN 结型结构，主要用于红外光接收与光电检测场合。器件对 940nm 波段敏感，兼顾高灵敏度与低暗电流，适合在紧凑型光电模块、光学开关及手持设备中使用。
二、主要参数
- 晶体管类型：NPN 光电晶体管
- 集射极击穿电压 Vceo：30 V
- 最大集电极电流 Ic：20 mA
- 最大耗散功率 Pd：75 mW
- 暗电流（暗态漏电流）：100 nA（典型）
- 峰值响应波长：940 nm（红外）
- 工作温度范围：-25 ℃ ~ +85 ℃
- 封装形式：SMD，外形尺寸约 3.0 × 2.6 mm
- 包装：TR8 表示 8mm 带卷（Tape & Reel）自动贴片供料
三、主要特性
- 对 940 nm 红外光具有良好响应，适配常见红外发光二极管（IR LED）。
- 暗电流低（≈100 nA），在无光环境下输出噪声小，利于低光照检测精度。
- 小体积 SMD 封装，便于表面贴装自动化生产与高密度电路板设计。
- 耐压与功耗指标适中，可在一般低功耗传感与开关电路中安全工作。
四、典型应用
- 红外遥控与接收模块（与940nm LED配套）
- 光电开关、光栅/编码器、转速/位置检测
- 接近/物体检测、计数器与物料检测系统
- 小型光电隔离与手持设备的光学传感单元
五、封装与安装建议
- 封装为 3×2.6 mm SMD，建议参考厂商提供的封装图与焊盘设计以优化光学视角与机械强度。
- 采用标准回流焊工艺，遵循亿光的回流曲线与湿存储等级（若无特殊说明，建议干燥储存并按回流时限严格控制）。
- TR8 带卷包装适合贴片机直接上料，便于大批量生产。
六、使用注意与可靠性提示
- 注意最大耗散功率 Pd=75 mW，避免长期在接近额定耗散下工作，可通过降低工作电压或限制集电极电流来保护器件。
- 在设计光电接口时，考虑暗电流 100 nA 对灵敏度的影响，必要时采用积分或滤波电路以提高信噪比。
- 环境温度超出 -25~+85 ℃ 范围可能影响参数稳定性与寿命，户外或高温场合需加保护或散热。
- 避免强光直射或高能脉冲光照射引起瞬态饱和或永久损伤；生产和装配过程中注意防静电措施。
七、典型电路与设计提示
- 常见接法为共射极结构：光电晶体管集电极接至 VCC，通过上拉电阻 R 拉到电源，发出电平到 MCU/逻辑端；基准建议在 10 kΩ~1 MΩ 范围内选择，根据所需响应速度与灵敏度权衡。
- 若需快速响应，可降低电阻值以增加偏置电流，但需保证不超过 Ic=20 mA 极限并控制功耗。
- 对于远距或弱光场合，可与前级放大器配合，或使用透镜/光管集中光线以提高接收效率。

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.
