PD95-21B/TR10 产品概述
一、产品简介
PD95-21B/TR10 为 EVERLIGHT（台湾亿光）生产的一款 940nm 波段感光二极管（Sensor Photodiode），针对红外接收与近红外检测应用优化设计。器件采用 2-SMD 封装并具备 Z 型弯脚结构，便于表面贴装并在系统中实现可靠的光轴对准。
二、主要电光参数
- 峰值波长：940 nm，适配常见 940 nm 红外发光二极管和遥控/通信源。
- 光谱响应范围：730 nm ~ 1100 nm，可覆盖近红外宽谱检测需求。
- 直流反向耐压（Vr）：32 V，提供较宽的偏压裕度以满足速度与线性要求。
- 暗电流：典型 10 nA，低暗电流有利于提高检测灵敏度与信噪比。
- 工作温度范围：-25 ℃ ~ +85 ℃，适用于多数工业和消费类环境。
三、封装与机械特性
封装为 2-SMD，Z 型弯曲引脚设计：
- 有利于在装配后保持适当的接收高度与光学间隙，便于与发射端对准。
- 兼容常规回流焊工艺（建议遵循厂方的回流曲线与湿敏等级说明）。
- TR10 表示卷带包装，适合自动贴装生产线（具体包装数量请参照厂家出货信息）。
四、典型应用场景
- 红外遥控接收与数据通信（IR remote、IR link）。
- 近距离光学传感（接近传感、手势识别、遮挡检测）。
- 工业光电开关、编码器和光幕检测单元。
- 医疗与安防中近红外信号的采集。
五、使用建议与电路接口
- 常配合反向偏压使用以提高响应速度和线性度；建议在设计时采用跨阻放大器（TIA）进行小电流信号放大并控制带宽与噪声。
- 由于暗电流和环境光会影响低光照下测量精度，可结合带通光学滤光片与软件滤波增强系统鲁棒性。
- PCB 布局应注意接地回路与输入节点的寄生电容控制，以降低噪声和提高带宽。
六、可靠性与选型要点
- 在高温或强光环境下，暗电流及响应特性可能随温度变化，应在规格边界内验证实际系统性能。
- 若系统对响应速度或动态范围有更高要求，可根据偏压、负载电阻和放大器带宽进一步优化。
- 选型时确认封装高度、端子形式与贴装方向，以确保光轴与外壳/透镜结构匹配。
总结：PD95-21B/TR10 以其 940 nm 峰值、宽谱响应、低暗电流和 2-SMD Z 型封装，为需要稳定近红外接收的消费及工业类产品提供了高性价比的解决方案。欲获取完整电气特性曲线、回流焊规范和封装图纸，请参阅 EVERLIGHT 官方数据手册或联系供应商技术支持。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
