2SD1898G-Q-AB3-R 是 UTC(友顺)推出的一款 NPN 功率型晶体管,适用于中低功率开关与放大场合。典型参数为:集电极电流 Ic 可达 1A、集电极-发射极击穿电压 Vceo 80V、耗散功率 Pd 500mW,配 SOT-89-3 小型封装,适合空间受限的便携与板载应用。
封装为 SOT-89-3,体积小、焊接方便,适合表面贴装生产。封装散热能力有限,Pd 为 500mW 表明在无额外散热条件下不宜长时间在高电流高电压下工作。实际电路中应注意热沉面积和 PCB 铜箔扩展,必要时采用散热铜区或多层板热通孔以降低结壳温升并做好功率和温度的降额设计。
总结:2SD1898G-Q-AB3-R 在体积与性能之间提供了良好平衡,适用于需要中等电压耐受、较高增益和有限功率散耗的便携或板载电路。选型时以实际 PCB 散热条件和占空比分配为关键考量。若需引脚图、热阻或更详细参数,请参考 UTC 官方数据手册。

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.
