PC817X3YSZWC 产品概述

一、产品概述

PC817X3YSZWC 是夏普(SHARP)出品的一款晶体管输出光耦,封装为常见的 DIP-4 直插式封装。器件内部由输入红外发光二极管和输出 NPN 晶体管组成,用于实现输入与输出之间的电气隔离和信号传输。该器件以 5kVrms 的隔离耐压、较宽的工作温度范围和中等开关速度,适用于多种工业与消费类电子隔离场合。

二、主要参数

  • 输入正向压降(Vf):1.2V(If = 指定测试电流条件)
  • 最大正向电流(If):50mA(建议按额定值及散热条件使用并留裕量)
  • 输出最大电流:50mA(持续)
  • 输出负载电压上限:80V(Vce 最大)
  • 直流反向耐压(Vr,LED):6V(反向电压请勿超过该值)
  • 隔离电压(Vrms):5000V(耐压等级,符合高隔离需求)
  • 上升时间(tr):约 4μs;下降时间(tf):约 3μs(中速开关特性)
  • 工作温度:-40℃ 至 +100℃
  • 最大耗散功率(Pd):200mW(输出晶体管最高功耗限值)
  • 封装:DIP-4(便于穿孔安装与手工焊接)

三、特点与优势

  • 高隔离电压(5kVrms),适合需要高安全隔离的电源与信号接口。
  • 输出可承受高达 80V 的负载电压,扩展了应用场景(例如高电压测控回路)。
  • 中等开关速度(μs 级),在多数控制与信号隔离应用中响应较快且抗干扰能力好。
  • 宽温度范围适用工业级环境,可靠性高。
  • DIP-4 封装易于替换、调试与批量装配。

四、典型应用

  • 开关电源反馈隔离(次级到主控制侧)
  • 单片机、PLC 与高压电路之间的信号隔离
  • 工业控制输入/输出接口、继电器驱动隔离前端
  • 通讯设备与测量仪器的地回路隔离
  • 家电、电机驱动器等需要电气隔离的场合

五、典型电路连接与使用注意

  • 输入侧:LED 需串接限流电阻以控制 If,不应长期超过 50mA;避免反向电压超过 6V,可并联反向保护二极管于特殊场合。
  • 输出侧:按图常用为开集电极结构,需外接上拉电阻到所需电源;确保 Vce 不超过 80V,且输出功耗(Vce × Ic)不超过 200mW。
  • 开关特性:tr ≈ 4μs、tf ≈ 3μs,适合中低频率开关,不建议用于高频高速信号传输。
  • 设计时应作热耗散与冗余考虑,必要时降低平均 If 与输出电流以延长寿命并提高可靠性。
  • PCB 布局上注意保持输入与输出之间的爬电距离与空气间隙,配合系统接地策略以满足安全规范。

六、存储与可靠性建议

  • 存储及工作环境避免高湿与腐蚀性气体,长时期静置时按厂商推荐湿热与干燥贮存。
  • 焊接时应遵循元件焊接温度与时间限制(参考制造商工艺说明),DIP 封装适合波峰焊或手工焊接,焊接后建议进行功能与绝缘测试。
  • 在关键安全类应用中建议加冗余或复核电路,定期检查绝缘与传输性能。

Sourcing availability signal

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
