AOTE（奥特） PC817DS 产品概述
一、产品简介
PC817DS 是 AOTE（奥特）出品的一款单通道光电耦合器，输入为直流 LED，输出为光电三极管。采用 SMD-4 表面贴装封装，适用于需要电气隔离与信号传递的紧凑型设计。器件具有高隔离电压、较宽的工作温度范围和良好的传输效率，适合工业与消费类电子场合。
二、主要规格参数
- 输入类型：DC（发光二极管）
- 输出类型：光电三极管（单通道）
- 正向压降 Vf：1.2 V
- 正向电流 If（最大）：50 mA
- 输出电流（最大）：50 mA
- 直流反向耐压 Vr：6 V
- 负载电压（最大）：80 V
- 隔离电压 Vrms：5 kV
- 电流传输比 CTR：最小 80%，最大/饱和值 600%
- 集射极饱和电压 VCE(sat)：200 mV @ 1mA,20mA
- 上升时间 tr：4 μs；下降时间 tf：3 μs
- 工作温度：-55 ℃ ~ +110 ℃
- 封装：SMD-4
- 品牌：AOTE（奥特）
三、关键性能说明
- 高隔离：5 kV RMS 隔离能力，适合高压侧与低压侧安全隔离。
- 宽 CTR 范围：最低 80% 保证稳健的传输能力，最高可达 600% 适用于低驱动电流场景。
- 低 VCE(sat)：200 mV 的集射极饱和电压在开关应用中可降低功耗与发热。
- 响应速度：上升/下降时间分别为 4 μs / 3 μs，兼顾速度与噪声抑制。
四、典型应用
- 微控制器与高压电路之间的信号隔离
- 开关电源（SMPS）、电机驱动与逆变器控制信号隔离
- 通信设备、仪表与工业控制系统的电平转换与防护
- 继电器/晶闸管驱动前的隔离及保护电路
五、推荐使用与封装信息
- 建议在 LED 输入侧串联限流电阻以保证 If ≤ 50 mA，并根据所需 CTR 选择合适工作点。
- 输出侧负载电压不超过 80 V，输出电流不超过 50 mA。
- SMD-4 封装适合自动贴装与回流焊流程，建议遵循厂商推荐的焊接曲线与 PCB 布局以保证隔离距离与散热。
六、使用注意事项
- 请根据实际电路环境对 CTR 进行考虑并留有余量，器件 CTR 随温度和时间会变化。
- 在高压应用中，请同时关注爬电距离与固体绝缘要求，以满足系统安全标准。
- 避免长时间在极限参数下工作，以延长器件寿命并保证可靠性。
PC817DS 以其高隔离、电流传输效率和紧凑 SMD 封装为主流隔离需求提供了平衡的性能选项，适合要求体积小且需可靠隔离的电子设计。

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.
