SS8050 是一种高性能的 NPN 双极晶体管(BJT),由时科(SHIKUES)品牌生产,适用于各种电子设备中的功率放大和开关应用。以下是对 SS8050 的详细介绍,包括其关键参数、特性、应用场景以及使用注意事项。
SS8050 具有较高的集电极电流能力,最大可达 1.5 A,这使得它非常适合于需要较大电流驱动的应用,如大功率音频放大器、电机驱动器和其他高电流设备。
该三极管在工作状态下具有较低的集电极-发射极饱和电压(VCE(sat)),仅为 500 mV @ 800 mA, 80 mA。这意味着在开关或放大模式下,能耗较低,效率更高。
SS8050 的直流电流增益(hFE)为 200 @ 100 mA, 1 V,这表明它具有良好的信号放大能力,适用于需要稳定和可靠信号放大的场景。
120 MHz 的特征频率使得 SS8050 适用于中频和高频应用,如无线通信设备、射频放大器等。
由于其高电流能力和低饱和电压,SS8050 非常适合用于音频放大器中,特别是那些需要驱动大负载的应用。
在电机驱动应用中,SS8050 可以提供足够的电流来控制和驱动小型到中型的直流电机。
其高切换速度和低饱和电压使得 SS8050 适用于开关电源中的功率开关元件。
在无线通信设备中,SS8050 可以用于射频放大器或其他需要中频和高频放大的模块。
尽管 SS8050 的功率耗散为 350 mW,但在高电流和高频率操作下,仍需要注意热管理。建议使用适当的散热措施,如散热片或散热器,以确保设备在正常工作范围内。
确保操作电压不超过最大允许值(Vceo = 25 V),以避免损坏晶体管。
由于直流电流增益较高,需要确保基极输入信号稳定且适当,以避免过度饱和或过载。
如果需要更高的总电流能力,可以考虑并联多个 SS8050。但是,必须确保所有并联的晶体管之间有良好的热接触和均匀的电流分配。
SS8050 是一种功能强大的 NPN 三极管,适用于各种需要高电流和高频率操作的电子设备。其低饱和电压、 高直流电流增益和高特征频率使其成为音频放大器、电机驱动器、开关电源以及无线通信设备等领域的理想选择。通过遵循适当的使用注意事项,可以充分发挥 SS8050 的性能优势。
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.
