PT204-6C 产品概述
一、产品简介
PT204-6C 是台湾亿光（EVERLIGHT）出品的一款红外接收管（光电晶体管，NPN 型），常用于红外线遥控、光电检测与非接触式传感场合。封装为插件式透明聚合物透镜，直径约 3 mm，便于穿孔板或面板安装。器件对 940 nm 附近红外光响应最强，响应速度与灵敏度适中，适合一般家电与消费类电子的遥控接收与光电开关应用。
二、主要电气参数
- 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（无光）IDDark：100 nA（典型）
- 峰值响应波长：940 nm
- 集—射极饱和电压 VCE(sat)：0.4 V（IC = 2 mA）
- 工作温度范围：-40 ℃ ~ +85 ℃
三、典型特性与应用场景
PT204-6C 在 940 nm 附近灵敏度最佳，适用于：
- 红外遥控接收模块（家电遥控、玩具）
- 非接触光电开关、计数器、侵入检测
- 简单的光强检测与编码识别电路
器件响应快、暗电流低（约 100 nA），在低照度条件下仍能保持较好信噪比。VCE(sat) 仅 0.4 V（在 2 mA 下），便于与单片机或逻辑电路直接接口。
四、封装与机械特性
- 封装形式：插件（透镜型），外径约 3 mm
- 引脚排列适合标准穿 PCB 安装，利于批量装配与替换。
五、使用注意事项
- 尽量限制在额定 IC（20 mA）以内使用，并注意 PD（75 mW）限制：当 VCE 较高时，应相应降低 IC（例如在 5 V 电源下若 VCE≈5 V，则最大 IC 以不超过 ~15 mA 为宜，以免超过耗散功率）。
- 推荐工作点：若以 VCC = 5 V，欲使 IC ≈ 2 mA，可在集电极串联上拉电阻 R ≈ (5 V − 0.4 V) / 2 mA ≈ 2.3 kΩ（常见电路为集电极接 VCC，经上拉电阻，光照时集电极电位下降）。
- 避免强光直射或长时间高温环境，焊接时请遵守厂商热循环建议以免损伤封装或引脚。
- 注意防静电与正确接地，避免在装配或测试过程中产生静电放电损坏。
六、选型建议与替代提示
若应用需要更高电流或更高耗散，建议选用额定 Ic、Pd 更高的光电晶体管或采用外部放大电路；若需要更窄带或更高灵敏度，可考虑带滤光片或专用红外接收模块（含前置放大与滤波）。购买时确认批次与厂商规格书以确保参数一致。

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.
