  • 反向电压: 6V
  • 工作温度范围: -40℃ ~ +100℃
  • 正向电压: 1.2V
  • 负载电压: 35V
  • 输入电压类型: DC
  • 输出电流: 50mA
  • 输出类型: 光电三极管
  • 输出通道数: 1
  • 隔离电压(rms): 5kV
  • 集射极饱和电压(Vce(sat)@Ic, IF): 100mV @ 1mA, 20mA

封装和外观

PC817B 采用 SMD-4 封装,这是一种小型化的表面安装封装,适合现代电子产品的紧凑设计需求。这种封装方式不仅提高了生产效率,还减少了占用空间,非常适合用于高密度的 PCB 设计。

工作原理

PC817B 是一种光耦器设备,它通过光信号来实现电气隔离和信号传输。其内部结构包括一个发光二极管(LED)和一个光电三极管。 当输入端的 LED 接收到电流时,它会发出光信号,这些光信号被光电三极管检测到,从而控制输出端的电流。这种方式确保了输入端和输出端之间的完全电气隔离,防止了电噪声和高压电的干扰。

应用场景

PC817B 广泛应用于以下几个领域:

  • 工业控制系统: 在工业控制系统中,PC817B 可以用于隔离控制信号和执行设备之间的电气连接,提高系统的可靠性和安全性。
  • 医疗设备: 医疗设备需要严格的电气隔离以确保患者的安全,PC817B 因其高隔离电压和稳定性能而被广泛采用。
  • 通信设备: 在通信设备中,PC817B 可以用于信号传输和电气隔离,确保数据传输的稳定性和安全性。
  • 汽车电子: 汽车电子系统中也常见到 PC817B 的应用,用于控制和监测各种汽车功能,如发动机管理、安全系统等。

性能特点

  • 高隔离电压: PC817B 提供了 5kV 的 rms 隔离电压,这使得它能够在高压环境下工作,确保系统的安全性。
  • 快速响应时间: 上升时间为 4μs,下降时间为 3μs,这些快速响应时间使得 PC817B 适合于需要快速切换的应用场景。
  • 宽工作温度范围: 支持 -40℃ ~ +100℃ 的工作温度范围,使得 PC817B 可以在各种环境条件下稳定运行。
  • 低饱和电压: 集射极饱和电压仅为 100mV @ 1mA, 20mA,这降低了能耗并提高了效率。

安装和使用注意事项

  • 焊接: 由于采用 SMD 封装,需要使用适当的表面安装技术进行焊接。确保在焊接过程中避免过热,以防止损坏设备。
  • 电气布局: 在 PCB 设计中,应确保输入端和输出端之间有足够的物理距离,以避免电气干扰。
  • 环境条件: 在极端温度或湿度条件下使用时,应参考数据手册中的具体指南,以确保设备的可靠性。

总结

PC817B 晶体管输出光耦器是 Slkor(萨科微)的一款高性能产品,具有快速响应时间、宽工作温度范围和高隔离电压等优点。它广泛应用于工业控制、医疗设备、通信设备以及汽车电子等领域。通过选择 PC817B,可以显著提高系统的可靠性、安全性和效率。

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
