EVERLIGHT PT908-7C(BIN5) 产品概述
一、产品简介
PT908-7C(BIN5) 是台湾亿光（EVERLIGHT）出品的插件式光电二极管，峰值波长为 940nm。器件为小型插件封装，尺寸 4.5×5.7×2.25 mm，适合红外接收与检测类应用，便于手工或波峰焊接安装。
二、主要参数与封装
- 峰值波长：940 nm（对 940nm 红外光响应最佳）
- 封装形式：插件（Through-hole），外形尺寸 4.5×5.7×2.25 mm
- BIN5：表示出厂按某项关键性能（如响应度或暗电流）分档出货，具体分档标准请以官方数据表为准。
三、关键特性与性能要点
PT908-7C 对近红外有较高灵敏度，常用于调制红外信号接收或环境光测量。器件响应快且噪声低（相对通用光电二极管），在需要抗环境光干扰时，配合调制技术与光学滤光片可获得更好性能。为达到最快响应，常在反向偏压下工作；若要求最低噪声，可采用零偏或低偏压工作方式。
四、典型应用场景
- 红外遥控接收模块
- 近距物体检测、接近传感器与断料检测
- 简易光纤接收端或短距离光通讯（需匹配光学与驱动电路）
- 自动门、消费电子与工业传感应用
五、接口与使用建议
- 驱动/读出：推荐使用跨阻放大器（TIA）将光电流转换为电压，便于后端信号处理；如仅做开关检测，也可配合偏置与限流电阻。
- 抗干扰：采用 38–40 kHz 等载波调制与带通解调可有效抑制环境直流与工频干扰；在光学上可加 940nm 通带滤光片或遮光罩。
- PCB 布局：光端留足开窗空间，走线短且屏蔽敏感节点，减小寄生电容与噪声耦合。
六、存储与焊接注意事项
器件对静电敏感，存储和操作时应采取防静电措施。插件封装适合手工或波峰焊接，焊接时请参考厂商推荐的温度/时间曲线并遵循 IPC 焊接建议，避免过长高温暴露以保护封装与内部键合线。
七、选型与替代建议
选型时关注响应度、暗电流、响应时间与 BIN 分类，以满足灵敏度与稳定性要求。如需更高灵敏度或更快带宽，可参考同类硅光电二极管或雪崩光二极管（APD）；对环境光抑制要求高者，可选带有集成滤光或更窄谱响应的型号。最终参数请以 EVERLIGHT 官方数据表为准。
如需我帮您对接电路实例（跨阻放大器参考值、滤波方案或 PCB 布局示意），可提供工作电压和目标带宽，我将给出针对性建议。

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.
