瑞萨PS2801C-4-F3-A/M 四通道晶体管输出光耦产品概述

一、核心定位与封装特性

PS2801C-4-F3-A/M是瑞萨电子推出的四通道晶体管输出型光电耦合器,专为多通道电气隔离场景设计。采用SOP-16小封装,在16引脚内集成4组独立光耦通道,既节省PCB空间,又简化多通道隔离电路的设计复杂度,适配高密度、紧凑化的电子系统。

二、关键电气参数深度解析

该光耦参数覆盖输入、输出、隔离及响应特性,支撑多场景需求:

  • 输入特性:DC直流输入,正向压降(Vf)1.2V,最大正向电流(If)30mA,总功耗(Pd)80mW(单通道平均功耗约20mW),需注意多通道同时工作时的总功耗控制。
  • 输出特性:光电三极管输出,集射极饱和电压(VCE(sat))低至300mV(@10mA/2mA),导通损耗小;最大输出电流30mA,负载电压支持80V,可驱动中等功率负载;电流传输比(CTR)50%~400%,覆盖宽输入电流区间,适配不同驱动需求。
  • 隔离与耐压:交流隔离电压(Vrms)2.5kV,直流反向耐压(Vr)6V,有效阻断地环路干扰及高压串扰。
  • 响应速度:上升时间(tr)5μs,下降时间(tf)7μs,适合100kHz以内的中等频率信号传输,不支持MHz级高频应用。

三、典型应用场景适配

基于多通道、宽温宽及隔离特性,该光耦适配以下核心场景:

  • 工业控制:PLC数字量输入/输出隔离,解决工业现场电磁干扰;电机驱动电路信号隔离,保护控制端免受功率端干扰。
  • 通信设备:RS485、CAN总线等通信接口隔离,避免地电位差导致的信号失真;以太网交换机辅助控制信号隔离。
  • 电源系统:开关电源反馈回路隔离(电压/电流反馈),辅助电源信号隔离,提升电源安全性与稳定性。
  • 医疗设备:患者监护设备输入隔离,满足医疗安全标准要求。
  • 消费电子:智能家电多按键输入隔离,提升设备抗干扰能力与可靠性。

四、性能优势与竞争对比

相较于同类四通道光耦,该产品具备以下核心优势:

  • 宽CTR范围:50%~400%的CTR覆盖,无需因偏差频繁调整输入电流,降低设计难度。
  • 低饱和压降:300mV的VCE(sat)远低于部分同类产品(≥500mV),导通损耗更小,负载电压利用更充分。
  • 工业级温宽:-55℃~+100℃工作温度,覆盖工业极端环境(户外设备、高温车间),可靠性更高。
  • 高集成度:SOP-16封装集成4通道,比4个单通道光耦节省约50%PCB空间,简化布局与焊接。
  • 原厂可靠性:瑞萨制造工艺保障长期稳定性,适合量产应用,降低后期维护成本。

五、使用注意事项

为确保可靠性与寿命,需注意:

  1. 输入电流限制:单通道If≤30mA,总功耗≤80mW(单通道If≤16.7mA@Vf=1.2V),避免LED过流。
  2. 输出负载约束:负载电压≤80V,输出电流≤30mA,防止光电三极管过压过流。
  3. 响应速度适配:仅适用于100kHz以下信号,高频需选高速光耦(如6N137)。
  4. 焊接存储:遵循瑞萨焊接工艺(回流焊峰值260℃,时间≤30s);存储环境-40℃~+85℃、湿度≤85%,避免静电损伤。

总结

PS2801C-4-F3-A/M以高集成度、宽CTR、低饱和压降、工业级温宽为核心竞争力,精准适配工业控制、通信、电源等多领域隔离需求,平衡性能与成本,是设计中兼顾可靠性与效率的可靠选择。

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.
