PC817B 产品概述（AOTE 奥特，DIP-4 光电三极管输出）
一、产品简介
PC817B 是一款单通道光耦合器，输入为 LED，输出为光电三极管，封装为标准 DIP-4。器件提供高达 5kVrms 的隔离电压，适用于需要信号隔离、位移电位器接口、开关电源反馈与微控制器输入保护等场合。品牌：AOTE（奥特）。
二、主要性能参数
- 隔离电压（Vrms）：5 kV
- 输入类型：DC（发光二极管）
- 正向压降（Vf）：典型 1.2 V
- 直流反向耐压（Vr）：6 V
- 电流传输比（CTR）：最小 130%，最大/饱和值 260%
- 输出类型：光电三极管（NPN 型）
- 输出电流：可达 50 mA
- 负载电压：最高 80 V
- 集-射极饱和电压 VCE(sat)：200 mV @ 1 mA, 20 mA
- 上升/下降时间：tr = 4 μs，tf = 3 μs
- 工作温度：-55 ℃ ～ +110 ℃
- 输出通道数：1；封装：DIP-4
三、特点与应用
- 高隔离电压，适合需要安全/噪声隔离的电路。
- CTR 较高（130%~260%），在低驱动电流下也能获得较大输出电流增益。
- 响应速度中等（μs 级），适合一般数字信号隔离、继电器驱动、传感器接口等。
- 小体积 DIP-4 便于面包板与传统 PCB 布局。
四、设计注意事项
- 输入侧需串联限流电阻：R = (Vdrive - Vf) / If，确保 If ≤ 50 mA。
- CTR 会随温度、制造批次及长期老化变化，若为精密设计请按最小 CTR 计算或加冗余。
- 输出在高电压（≤80 V）工作时注意功耗与散热，避免长期 50 mA 输出导致过热。
- 直流反向耐压仅 6 V，避免反向电压损伤 LED。
- 为满足安全规范，布线需保证爬电与间隙距离，并考虑外壳与板间绝缘。
五、可靠性与封装
- 工作温度宽，适合工业级应用（-55 ℃ ～ +110 ℃）。
- DIP-4 塑料封装便于插装与手工焊接，但注意焊接温度与时间，避免封装应力与内部失效。
六、选型与采购建议
- 若需更快响应或更高 CTR 精度，可考虑带逻辑门输出或达林顿结构的替代型号。
- 采购时注明品牌与封装（AOTE PC817B DIP-4），并确认样品批次以验证 CTR 与时序特性。
以上为 PC817B（AOTE）光电晶体管输出光耦的概要说明，可根据具体电路要求调整驱动电流与外围保护电路。

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.
