PS2811-1-F3-A 产品概述
一、器件简介
PS2811-1-F3-A 为 RENESAS（瑞萨）出品的小型光电耦合器，采用 4 引脚 SSOP-4 封装，输入为直流 LED，输出为光电三极管。器件通过光耦隔离输入与输出，适用于需要信号隔离与逻辑电平转换的场合，体积小、安装方便，适合表面贴装工艺。
二、主要电气参数
- 输入正向压降（Vf）：1.15 V（典型）
- 正向电流（If，最大）：50 mA
- 输出类型：光电三极管，最大输出电流（集电极电流）：40 mA
- 集—射极饱和电压（VCE(sat)）：约 300 mV（典型测试点：Ic=1 mA，If=0.2 mA）
- 直流反向耐压（Vr）：6 V
- 负载电压（最大 VCEO）：40 V
- 隔离耐压（Vrms）：2.5 kV
- 电流传输比（CTR）：最小 100%，最高可达 400%（随 If、温度与测试条件变化）
- 响应速度：上升时间 tr ≈ 4 μs，下降时间 tf ≈ 5 μs
- 工作温度范围：-55 ℃ ～ +100 ℃
三、关键特性与优势
- 高隔离电压（2.5 kVrms），保障输入与输出之间良好安全隔离。
- 宽 CTR 范围（100%–400%），便于在低驱动电流条件下仍获得充足输出电平。
- 低 VCE(sat) 有助于减少开关损耗并提高输出驱动能力。
- 小型 SSOP-4 封装，便于在空间受限的 PCB 上实现表贴安装与自动化组装。
四、典型应用场景
- MCU 与高压/噪声侧电路的信号隔离与接口保护。
- 电源模块的反馈与监控信号隔离。
- 工业控制、家电与通信设备中的低频开关与逻辑隔离。
- 需要直流隔离且对速度要求不高（微秒级）的场合。
五、选型与使用建议
- 若需更高隔离或更快响应，请参考 RENESAS 系列中更高规格或高速型型号。
- 设计时根据目标输出电流选择合适的输入 If 与限流电阻，同时留意 CTR 的散布以保证最差情况仍能满足逻辑阈值。
- 输出侧应配置合适的上拉电阻与吸收保护，防止瞬态电压超限。
- 在耐压和安全相关应用中，遵循 PCB 间距与爬电距离规范，确保器件隔离等级的实现。

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.
