PC817C 是一种高性能的晶体管输出光耦器件,属于GOODWORK(固得沃克)品牌的产品系列。它采用光电三极管结构,提供了优秀的电气隔离和信号传输性能,广泛应用于各种电子设备和系统中。
PC817C 采用 DIP-4 封装形式,也有 SMD-4P 封装选项,适应不同应用场景下的安装需求。这种封装方式不仅便于手动焊接,也支持自动化生产流程。
PC817C 的核心组成部分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,这些光信号通过内部隔离结构传递到光电三极管,从而控制输出端的电流。这种结构确保了输入和输出之间的电气隔离,防止高压或噪声信号对系统造成干扰。
高隔离电压: PC817C 提供了高达 5kV 的rms隔离电压,这使得它在需要高电气隔离的应用场景中尤其有用,例如工业控制系统、医疗设备和电力电子设备。
宽工作温度范围: 该器件能够在 -55℃ ~ +110℃ 的广泛温度范围内正常工作,这使得它适用于各种环境条件下的应用。
快速切换时间: 上升时间为 6μs,下降时间为 5μs,这些快速切换时间使得 PC817C 适合于需要高速信号传输的应用,如数字逻辑电路和通信系统。
低饱和电压: 集射极饱和电压(Vce(sat))仅为 100mV @ 1mA, 20mA,这降低了能耗并提高了系统的整体效率。
高输出电流: 最大输出电流可达 50mA,这使得 PC817C 能够驱动较大的负载,例如继电器、电机或其他高电流设备。
工业控制系统: 在工业自动化中,PC817C 可用于隔离控制信号和高压设备之间的电气连接,确保系统的安全性和可靠性。
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。PC817C 的高隔离电压和宽工作温度范围使其成为这种应用的理想选择。
电力电子设备: 在电力电子领域,如变频器、UPS等设备中,PC817C 可用于控制和监控高压部分,防止电气噪声和高压干扰。
通信系统: 快速切换时间和低延迟特性使得 PC817C 适合用于高速数据传输应用,如光纤通信系统中的信号传输模块。
汽车电子系统: 汽车电子系统中需要耐受严酷环境条件的光耦器件。PC817C 的宽工作温度范围和高隔离电压使其成为汽车电子应用的一个不错选择。
PC817C 晶体管输出光耦器件以其出色的性能和多样化的应用场景,成为电子工程师和设计师在开发高可靠性、高速信号传输系统时的首选器件。其高隔离电压、快速切换时间、低饱和电压以及宽工作温度范围,使得它在各个行业中都有广泛的应用前景。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
