SS8050 是一种高性能的双极结晶体管(BJT),属于NPN类型,适用于广泛的电子应用场景。由晶导微电子公司生产,SS8050 以其出色的电气特性和可靠性而受到广泛认可。
以下是SS8050的一些关键参数:
SS8050 因其优异的性能和小巧的SOT-23封装,非常适合各种电子设备中需要高效能和紧凑设计的场景。以下是一些典型的应用领域:
放大器和开关电路:
驱动电路:
自动控制系统:
消费电子产品:
工业控制设备:
直流电流增益(hFE): SS8050 的直流电流增益为120 @ 100 mA, 1 V,这意味着它可以提供稳定的信号放大效果,适用于需要可靠信号传输的应用。
特征频率(fT): 特征频率达到100 MHz,这使得SS8050 在高频应用中表现出色,能够处理高速信号。
集射极击穿电压(Vceo): 集射极击穿电压为25V,这提供了足够的耐压能力,确保在正常工作条件下不会因过压而损坏。
集电极-发射极饱和电压(VCE(sat)): 饱和电压仅为500 mV @ 800 mA, 80 mA,这意味着在饱和状态下能耗较低,提高了整体效率。
集电极截止电流(Icbo): 极低的集电极截止电流(100 nA)确保了在无信号输入时能耗极低,有助于降低整体系统的能耗。
热管理: 尽管SS8050 具有宽泛的工作温度范围,但在高功率应用中仍需要适当的散热措施,以确保其长期可靠运行。
过流保护: 由于最大集电极电流为1.5A,建议在设计时加入过流保护措施,以防止因过流而导致晶体管损坏。
静电保护: 作为电子元器件,SS8050 对静电敏感。因此,在处理和安装过程中,应采取必要的静电保护措施。
SS8050 是一种功能强大且可靠的NPN三极管,适用于各种需要高性能和紧凑设计的电子应用场景。其优异的电气特性、宽泛的工作温度范围以及小型化的SOT-23封装,使其成为许多工程师和设计师的首选元件。通过合理设计和使用,SS8050 可以帮助实现高效、可靠和稳定的电子系统。

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.
