PS2701-1-L 光耦(光电三极管输出)产品概述

一、产品简介

PS2701-1-L 是 AOTE(奥特)提供的一款单通道光电耦合器,采用 SOP-4 封装,输入端为直流 LED,输出端为光电三极管。器件强调高隔离电压与宽范围电流传输比(CTR),适合低电平逻辑隔离、模拟/数字信号传输和电源反馈等场景。

二、主要参数

  • 输入类型:DC(LED 驱动)
  • 正向压降 Vf:约 1.2 V(在额定 If 下)
  • 正向电流 If(最大):50 mA
  • 输出类型:光电三极管(单通道)
  • 输出电流(最大集电极电流):50 mA
  • 集-射极饱和电压 VCE(sat):≈0.1 V(测试条件 IF=20 mA、IC=1 mA)
  • 直流反向耐压 Vr:6 V
  • 负载电压(最高):80 V
  • 隔离电压 Vrms:3.75 kV(典型绝缘强度)
  • 电流传输比 CTR:最小 80%,可达 600%(随 If、温度与负载变化)
  • 上升时间 tr:约 4 μs;下降时间 tf:约 3 μs
  • 工作温度范围:-55 ℃ ~ +110 ℃
  • 封装:SOP-4,单路输出

三、典型应用

  • MCU 与高压/噪声侧之间的信号隔离
  • 开关电源反馈(如次级到主控制端的光耦隔离)
  • 工业控制信号传输与隔离(继电器驱动、传感器接口)
  • 模拟信号隔离与低速数字通信

四、使用要点与设计建议

  • 驱动 LED 时确保 If 不超过 50 mA,长期工作推荐取较低 If 以延长寿命并降低发热。
  • 选择上拉电阻(或输入解耦)时考虑 CTR 的最低值(≥80%),例如若需 IC=1 mA,最低 If 可按 IC ÷ CTR_min 估算:If ≈1 mA ÷ 0.8 ≈1.25 mA。
  • 若用作开漏输出,计算上拉电阻示例(VCC=5 V,目标 IC=1 mA):R ≈(VCC−VCE(sat))/IC ≈ (5−0.1)/1 mA ≈ 4.9 kΩ。
  • 注意 CTR 随温度、If 与光电晶体管偏置变化,关键设计应基于最差情况(CTR_min)验证稳定性。
  • 器件响应速度为微秒级,适用于低中速信号,若需更高速应用请评估替代高速光耦或光电二极管/接收器组合。
  • PCB 布局建议在输入与输出侧保持足够爬电距离,隔离边界上避免穿越导体,必要时加装保險元件(如 TVS)提升系统抗干扰能力。

五、封装与可靠性

SOP-4 小外形便于贴片生产与密集布局;工作温度范围 -55 ℃ 至 +110 ℃ 满足工业级使用要求。3.75 kVrms 的隔离等级适合大多数信号隔离场合,但若需更高安全等级(例如医疗或某些安规要求)请核实系统所需的耐压与认证要求。

六、选型与采购建议

在选型时关注实际工作 If、所需输出电流和响应速度,若系统对 CTR 波动敏感,应选择 CTR 余量较大的型号或在电路中加入自动校正/反馈。AOTE(奥特)品牌的 PS2701-1-L 提供了良好的性价比和工业级耐温特性,适合中低速隔离场景批量采购与替换。

如需参考电路图、典型应用图或更详细的电气特性曲线(如 CTR 与 If 的关系、温度系数、封装引脚图),可提供进一步资料以便给出更具体的设计建议。

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
