PS2801C-4-F3-A/N是瑞萨电子(RENESAS)推出的四通道晶体管输出型光电耦合器,专为需要电信号隔离、抗干扰的电路场景设计,兼顾高可靠性、宽温适应性与紧凑封装,是工业控制、通信设备等领域的成熟解决方案。
该光耦属于光电隔离器件,通过光信号实现输入与输出电路的电气隔离,核心作用是切断地环路干扰、保护低压控制电路免受高压侧冲击。作为四通道集成产品,它在单封装内整合4组独立的光耦单元,适合高密度PCB设计需求。
从输入、输出、隔离到环境特性,产品参数覆盖核心应用需求:
2.5kV的交流隔离电压有效值,可有效隔离工业现场常见的1kV以上高压干扰(如电机驱动、电力线路);6V直流反向耐压防止输出端反向击穿,配合宽温设计(-55℃~100℃),能适应车间、户外等极端温度场景,长期运行稳定性可靠。
电流传输比(CTR)覆盖50%~400%的宽范围,既保证最小信号的有效传输(避免CTR过低导致信号丢失),又适配不同负载的驱动需求;5μs上升时间、7μs下降时间的快速响应,适合高速控制信号(如PLC脉冲信号、通信数据)的隔离传输。
130mV的集射极饱和压降(轻载/重载下一致),大幅降低输出端的功率损耗,尤其适合低功耗设计场景(如电池供电的便携设备、节能型工业控制器),同时减少发热,提升器件寿命。
采用SSOP-16-175mil封装,引脚间距175mil(约4.445mm),焊接兼容性好;单封装整合4组独立光耦,相比离散光耦节省50%以上的PCB空间,适合高密度电路(如小型PLC、通信模块)。
瑞萨电子作为全球半导体行业领导者,PS2801C系列光耦经过严格的质量认证(如ISO/TS 16949、AEC-Q100等,部分版本),生产工艺成熟,批量一致性高;产品 datasheet 提供完整的可靠性测试数据(如温度循环、湿度老化),适合工业级批量应用。
该产品凭借高隔离、宽温、多通道与低损耗的综合优势,成为工业控制、通信等领域信号隔离的高性价比选择,可直接替代同类进口光耦,适配主流电路设计。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
