PS2801-1-F3 晶体管输出光耦产品概述

PS2801-1-F3是瑞萨电子(RENESAS)推出的单通道晶体管输出型光耦,专为直流(DC)信号的电气隔离传输设计。该产品整合高电流传输比(CTR)、宽工作温度范围与强隔离耐压能力,适配工业控制、通信设备、家电等场景的中等电流/电压隔离需求,是瑞萨工业级光耦系列中的经典型号。

一、核心定位与典型应用场景

PS2801-1-F3属于光电三极管输出光耦,核心作用是通过光信号切断输入与输出电路的电气连接,同时实现信号传输(抗地环路干扰)。其参数匹配的典型应用包括:

  1. 工业PLC I/O隔离:隔离现场传感器/执行器与PLC核心电路,防止工业现场电磁干扰(EMI)串入控制系统;
  2. 开关电源反馈回路:在AC-DC/DC-DC电源中,实现输出电压反馈信号的隔离传输,配合PWM控制器稳压;
  3. 通信接口隔离:应用于RS485/RS232总线,隔离收发器与MCU,避免总线瞬态干扰损坏主控;
  4. 家电控制电路:空调、洗衣机的电机驱动隔离、电源模块反馈,适配宽温环境稳定工作。

二、关键电气特性详解

PS2801-1-F3的电气参数经工业级优化,核心特性如下:

1. 输入特性

  • 正向压降(Vf):典型值1.1V(If=20mA时),一致性好,输入功耗低;
  • 最大正向电流(If):50mA(峰值),满足突发信号传输;
  • 直流反向耐压(Vr):6V,防止输入侧反向电压损坏发光二极管。

2. 输出特性

  • 最大输出电流(Ic):50mA,可直接驱动小型继电器、三极管或MCU输入,无需额外放大;
  • 集射极饱和电压(VCE(sat)):典型值300mV(Ic=10mA时)、2mV(Ic=2mA时),饱和压降低,减少输出损耗;
  • 电流传输比(CTR):最小值80%,最大值600%,宽范围确保输入小电流(如2mA)即可驱动输出,降低输入功耗。

3. 隔离与耐压

  • 交流隔离电压(Vrms):2.5kV(有效值,1分钟测试),满足工业级隔离需求;
  • 最大负载电压(Vce(max)):80V,适配中等电压负载;
  • 工作温度范围:-55℃~+100℃,覆盖工业极端环境(户外、高低温车间),无需温度补偿。

4. 动态特性

  • 上升时间(tr):3μs,下降时间(tf):5μs,属于中速光耦,满足kHz级信号传输。

三、封装与可靠性设计

采用SOP-4-1.27mm封装,具备以下优势:

  1. 小尺寸高密度:引脚间距1.27mm,符合标准SOP规范,适配高密度PCB布局;
  2. 焊接兼容性:表面贴装工艺,适配自动化焊接设备,良率高;
  3. 工业级可靠性:经温度循环、湿度老化等严苛测试,MTBF(平均无故障时间)达数万小时,满足长期稳定运行。

四、选型与使用注意事项

确保稳定工作需注意:

  1. 输入限流电阻计算:( R=(Vin-Vf)/If_{max} ),例24V输入选470Ω/0.125W电阻;
  2. 输出负载限制:负载电压≤80V,电流≤50mA,避免过压/过流;
  3. PCB隔离设计:输入输出布线距≥2mm,符合2.5kV隔离要求,防爬电;
  4. 温度适配:CTR在宽温内保持≥80%,无需额外补偿电路。

五、总结

PS2801-1-F3凭借高CTR、宽温范围、强隔离能力与小封装设计,成为工业控制、通信领域的可靠隔离方案。其适配中等电流(50mA)、中等电压(80V)需求,无需额外放大电路,降低系统成本与复杂度。经市场验证,该产品稳定性优异,是工业级应用的优选光耦。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
