2SA1774EBTLR 是 ROHM(罗姆)生产的一款小信号 PNP 双极型晶体管,封装为小型表面贴装封装 EMT3F(同 SC-89 / SOT-416FL / SOT-490 系列),以卷带(TR)形式供货。该器件额定集电极击穿电压 50V、最大集电极电流 150mA、最大耗散功率 150mW,适用于低功耗小信号放大与开关场合。请注意:器件状态标注为“不适用于新设计”,在新产品开发时应考虑长期可获得性与替代器件。
以上参数为器件关键特性,具体在电路设计中应参照 ROHM 的官方数据手册获得完整曲线与典型值。
2SA1774EBTLR 采用 EMT3F(SOT-416FL / SC-89)超小型表面贴装封装,适合高密度 PCB 布局。由于封装体积小,热阻较大,最大耗散功率 150mW 在实际电路中需要按环境温度降额使用:
由于为 PNP 器件,常与 NPN 器件配合用于对称推挽、对称放大或电平转换。
如需更详细的特性曲线、引脚定义、典型应用电路与可靠性数据,请参考 ROHM 官方数据手册或联系供应商获得最新技术支持。

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.
