BAS70-04是国内半导体厂商富芯森美(FUXINSEMI)推出的一款小信号开关二极管,采用SOT-23(TO-236)表面贴装封装,主打低功耗、小体积、宽温适应性,适用于大多数低电流、低电压的电子电路设计。作为针对便携设备、智能穿戴、通信模块等场景优化的器件,其核心参数与可靠性设计围绕“小型化+稳定性”展开,是替代进口同类产品的经济适用型选择。
BAS70-04定位于小信号开关/整流专用器件,并非大功率整流管,应用场景集中在电流需求不高(≤70mA直流)、电压范围适中(≤70V反向)的电路中,典型应用包括:
需注意:该器件不适合大功率整流(如电源适配器、电机驱动),仅适用于小信号级别的开关与整流需求。
BAS70-04的核心参数围绕“低功耗、高可靠性”设计,具体如下:
BAS70-04采用SOT-23(TO-236)表面贴装封装,尺寸约2.9mm×1.6mm×1.1mm,优势显著:
此外,器件反向漏电流低、宽温稳定,经批量测试可保证1000小时以上长期工作寿命(典型场景下)。
富芯森美(FUXINSEMI)作为国内小信号器件厂商,产品以“高性价比、参数兼容进口”为核心竞争力:
该器件已在消费电子、IoT终端、工业控制等领域批量应用,验证了稳定性与适配性。
BAS70-04凭借SOT-23封装的小型化、100nA低漏电流的精密性、宽温适应性,以及FUXINSEMI的性价比优势,成为便携设备、智能穿戴、通信模块等场景的优选器件。其核心价值在于“平衡性能与成本”,既满足小信号电路基本需求,又降低终端研发与生产成本,是替代进口同类产品的可靠选择。

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.
