    • 该范围表示该三极管可以在极端温度条件下稳定工作,适用于各种环境下的应用。
  • 晶体管类型: NPN
    • NPN类型的三极管在基极上施加正电压时,会打开通路,允许电流从集电极流向发射极。
  • 特征频率(fT): 300 MHz
    • 表示该三极管在高频应用中的性能,适用于中高频电子设备。
  • 直流电流增益(hFE@Ic,Vce): 300 @ 10 mA, 1 V
    • 直流电流增益是指基极电流与集电极电流的比值,高增益意味着更好的放大性能。
  • 集射极击穿电压(Vceo): 40 V
    • 当基极未接通时,集电极和发射极之间可以承受的最大电压。
  • 集电极-发射极饱和电压(VCE(sat)@Ic,Ib): 300 mV @ 50 mA, 5 mA
    • 在饱和状态下,集电极和发射极之间的最小电压差,低饱和电压意味着更低的能量损耗。
  • 集电极截止电流(Icbo): 100 nA
    • 当基极未接通时,集电极和发射极之间的漏电流。
  • 集电极电流(Ic): 200 mA
    • 该三极管可以承受的最大连续工作电流。

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
