S8550 为 JSMSEMI(杰盛微)推出的一款小信号 PNP 双极型晶体管,采用 SOT-23 小封装,适用于便携式和空间受限的电路板设计。器件针对低压、低功耗及中等频率放大场合优化,兼顾开关与放大两类应用需求,是常见的通用型 PNP 器件之一。
以上参数为器件典型或最大额定值,电路设计请参照完整数据手册中的测试条件和曲线图。
S8550 为独立式三引脚元件,采用 SOT-23 小型表面贴装封装,便于自动贴装与批量生产。SOT-23 的热阻较大,单颗器件功耗受限,建议在 PCB 设计中配合铜箔散热片或多层结构以提升热量扩散能力。具体引脚排列请以厂商封装图为准。
S8550 适合需要 PNP 小信号放大或中等驱动能力的场合。若应用对功耗或饱和电压要求更严格,可考虑功耗更大或 VCE(sat) 更低的替代件;若需更高频率性能,可选取 fT 更高的器件。最终选型请结合实际工作电流、工作电压、散热条件和成本进行综合评估,并参考 JSMSEMI 的完整数据手册以获得详细特性与封装图。
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.
