BAS40-04 是由 FUXINSEMI(富芯森美)推出的一款肖特基二极管对,采用 SOT-23 小封装,内部为一对串联式二极管。该器件在中等电流和低正向压降场合表现优异,特别适用于需要低压降、快速响应和低反向漏电的便携与工业电子系统。典型工作结温范围为 -40℃ 到 +125℃,适应宽温度环境。
说明:1V@40mA 是两颗串联二极管在 40mA 时的总正向压降,单只器件正向压降约为该值的一半(约 0.5V),随电流和温度会有相应变化,设计时应留有裕量。
BAS40-04(FUXINSEMI)是一款面向低压降、低漏电和快速响应需求的串联肖特基二极管,适用于便携电源、信号整形和小功率整流等多种场景。设计时应注意封装热限制与峰值浪涌的非重复特性,合理布局与热管理可以显著提高系统可靠性。欲获得更详细的引脚定义、典型曲线与包装信息,请参阅厂商完整数据手册或联系 FUXINSEMI 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.
