BC847BS(品牌:YANGJIE 扬杰)为一款双通道小功率NPN双极型晶体管,采用SOT-363(微型六引脚)封装,内含两枚独立NPN晶体管。器件设计用于通用开关与低功耗放大场合,单管最大集电极电流100mA,集射极击穿电压Vceo为45V,耗散功率Pd为300mW(每管),适配高密度表面贴装电路(SMT)应用。
BC847BS 采用 SOT-363 微型封装,内含两颗独立NPN。封装体积小、焊盘密度高,适合表面贴装生产。由于单管耗散功率为300 mW,设计时应注意PCB散热:合理增大铜箔面积、使用热 vias 或在高功率场合限制平均集电极电流,以避免过热导致性能退化或失效。

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.
