- 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-4P 封装，适合于表面安装工艺。这使得它在现代电子产品设计中非常便于使用和集成。
工作原理
PC817B 由一个发光二极管（LED）和一个光电三极管组成。当输入端的LED受到电流驱动时，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。这种结构实现了输入和输出之间的电气隔离，有效防止电磁干扰和提高系统的安全性。
应用场景
- 电气隔离: PC817B 因其高达 5kV 的隔离电压，非常适合用于需要电气隔离的应用，如工业控制系统、医疗设备、通信设备等。
- 信号传输: 由于其快速的上升和下降时间（分别为 6μs 和 5μs），PC817B 可以处理高速信号传输，适用于数据通信、控制系统等领域。
- 驱动负载: 输出电流可达 50mA，足以驱动小型负载，如继电器、LED显示屏等。
- 温度范围广泛: 支持从 -55℃ 到 +110℃ 的广泛工作温度范围，使其在极端环境下也能稳定运行。
特点
- 高隔离电压：5kV 的隔离电压保证了输入和输出之间的安全性。
- 快速响应时间：上升和下降时间分别为 6μs 和 5μs，适合高速信号处理。
- 宽工作温度范围：从 -55℃ 到 +110℃ 的工作温度范围，使其适用于各种环境条件。
- 低饱和电压：集射极饱和电压仅为 100mV @ 1mA, 20mA，减少能耗并提高效率。
- 小型化封装：SMD-4P 封装方便表面安装，节省空间。
使用注意事项
- 电流限制：确保输入和输出电流不超过指定值，以避免损坏设备。
- 温度控制：尽管支持广泛的工作温度，但应尽量避免在极端温度下长时间运行。
- 静电保护：在处理和安装过程中，应采取必要的静电保护措施，以防止静电损伤。
总结
PC817B 晶体管输出光耦器是 GOODWORK（固得沃克）品牌的一款高性能产品，通过其优异的隔离性能、快速响应时间和宽工作温度范围，广泛应用于各类电子设备中。其小型化封装和低能耗设计使其成为现代电子产品设计中的理想选择。通过正确使用和维护，PC817B 可以提供可靠的信号传输和电气隔离功能。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
