BAT54SQ是扬杰电子(YANGJIE) 推出的小信号肖特基势垒二极管(需明确:用户描述中“普通三极管”为信息偏差,肖特基二极管属于二极管范畴,与三极管结构、功能完全不同)。该器件专为低功耗、小电流场景设计,属于国产优质肖特基二极管,可广泛替代进口同参数型号(如BAT54系列),在消费电子、工业控制等领域具备高性价比优势。
BAT54SQ的核心参数围绕“小电流、低损耗、宽温可靠”设计,具体如下:
正向压降(Vf)为1V@100mA,导通损耗低,适合对电源效率要求较高的电路;平均正向整流电流(IF)为200mA,满足小功率直流供电需求。
直流反向耐压(Vr)达30V,可承受常规小信号电路的反向电压;反向漏电流(Ir)仅2uA@25V(25℃环境下),漏电流极小,反向截止性能稳定,避免电路功耗浪费或误触发。
非重复峰值浪涌电流(Ifsm)为600mA,可应对短时间瞬态电流冲击(如电源上电瞬间);工作结温范围覆盖**-55℃~+125℃**,支持工业级环境(低温、高温工况),同时满足消费电子的常规温度需求。
BAT54SQ采用SOT-23(TO-236)贴片封装,属于行业标准小封装:
基于其小电流、低损耗、小封装的特点,BAT54SQ主要应用于以下场景:
综上,BAT54SQ是一款性能均衡的小信号肖特基二极管,在小电流、低损耗、小封装场景中具备突出优势,是扬杰电子针对中低端市场推出的高性价比替代方案。

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.
