PS2805C-1-F3-A 产品概述

一、概述

PS2805C-1-F3-A 是瑞萨(RENESAS)出品的一款晶体管输出光电耦合器,采用单通道光电三极管输出设计,适用于需要电气隔离的数字/模拟信号传输场合。器件支持 AC/ DC 输入,具有较高的隔离耐压和宽工作温度范围,适合工业控制、电源监测及通信接口等应用。

二、主要参数

  • 隔离电压(Vrms):2.5 kV
  • 输入类型:AC、DC 均可
  • 输出类型:光电三极管(Phototransistor)
  • 输出电流(IC):最大 30 mA
  • 负载电压(VCEO/VCB 类似限定):最大 80 V
  • 正向压降(Vf):约 1.2 V
  • 正向电流(If)最大:30 mA
  • 电流传输比(CTR):最小 50%,最大(饱和值)400%
  • 集射极饱和电压(VCE(sat)):约 130 mV(测试条件 IF/IC 见规格书)
  • 上升时间 tr:5 μs @ If=2 mA,负载 100 Ω
  • 下降时间 tf:7 μs
  • 工作温度:-55 ℃ ~ +100 ℃
  • 通道数:1,封装:SOP-4,1.27 mm 芯距

三、产品特点与优势

  • 高隔离耐压(2.5 kVrms),适合高压与低压侧隔离;
  • 宽 CTR 范围(50%–400%),在不同输入电流下可获得较大输出幅度,便于灵活驱动;
  • 低 VCE(sat)(约 130 mV),在饱和导通时损耗小、发热低;
  • 支持 AC 与 DC 输入,应用更灵活;
  • 宽工作温度覆盖 -55 ℃ 至 +100 ℃,可靠性高,适应恶劣环境;
  • 标准 SOP-4 小封装,便于 PCB 布局与自动化贴装。

四、典型应用场景

  • MCU 与高压电路、开关电源控制回路的电气隔离;
  • 工业现场总线接口、传感器信号隔离;
  • 电源检测、零交叉检测与继电器驱动隔离;
  • 家电、安防及通信设备中低速信号隔离场合。

五、设计与使用建议

  • 在电路设计中应按最小 CTR(50%)进行保守计算,确保在最差情况下仍满足输出电流需求。
    例如:若 VCC=5 V,目标饱和电流 IC=0.5 mA,取 VCE(sat)≈0.13 V,则限流电阻 RL ≈ (5−0.13) / 0.5 mA ≈ 9.7 kΩ。实际设计应考虑器件公差与温漂。
  • 注意正向电流 If 不超过 30 mA 的最大额定值,长期工作建议留有余量(如 ≤20 mA)以延长寿命并降低热应力。
  • 输出侧允许的最大耐压(80 V)应勿超限,且保证 PCB 上的爬电距离与绝缘要求满足系统安规。
  • 若需提高开关速度,可在保证 CTR 的前提下增大驱动电流;上升/下降时间与 If、负载阻值相关。
  • 关注封装散热与环境温度,超过 100 ℃ 工作不可取;在高温或高输出电流下应做热设计。

六、封装与可靠性

SOP-4(1.27 mm)封装,单通道布局,适合批量贴装工艺。瑞萨品牌保证电子级制造与可靠性测试,适用于需要长期稳定隔离性能的工业与消费类电子产品。

备注:以上参数为器件关键特性摘要,具体应用时应参照 Renesas 官方规格书和典型应用电路以获得完整测试条件与限制值。

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.

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
