BAT54CW是富芯森美(FUXINSEMI) 推出的一款肖特基二极管,采用1对共阴极配置,封装形式为SOT-323(SC-70) 超小型表面贴装封装。作为低压小电流应用的核心器件,其设计兼顾低损耗、高频响应与小型化需求,广泛适配消费电子、小型电源等领域的电路设计。
BAT54CW的参数针对低压场景做了针对性优化,关键指标及意义如下:
BAT54CW采用SOT-323(SC-70) 封装,尺寸约为2.9×1.6×1.1mm(典型值),属于超小型表面贴装封装,可显著节省PCB布局空间,适配高密度电路设计(如便携式设备)。
引脚为共阴极结构:两个肖特基二极管的阴极共用一个引脚,阳极分别引出。具体引脚定义(参考标准SOT-323封装):
该配置无需额外设计阴极连接电路,可简化布线,适合双二极管协同工作的场景(如钳位、反向保护)。
结合参数特性,BAT54CW主要应用于低压小电流电子电路,典型场景包括:
BAT54CW在同类器件中具备以下核心优势:
为确保可靠工作,需注意以下要点:
BAT54CW凭借其低损耗、小型化与高可靠性,成为低压小电流电路设计的优选器件,可满足消费电子、小型电源等领域的多样化需求。

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.
