DSF1D 是 FUXINSEMI(富芯森美)推出的一款独立式快恢复高效率二极管,采用 SOD-123 小封装,面向开关电源、逆变器、整流与续流保护等中高电压、高频率功率电子应用。器件在-55℃至+150℃的工作结温范围内稳定工作,兼顾耐压、开关速度与低正向压降,适合体积受限但对效率和可靠性有要求的场合。
SOD-123 封装体积小,但散热能力有限。设计 PCB 时建议:
总结:DSF1D 以其 200 V 耐压、0.95 V @1A 的低 Vf 和 35 ns 的快恢复时间,适合体积紧凑且需兼顾效率与耐压的中高频功率应用。合理的 PCB 热设计与预计工况下的热分析是保证长期可靠性的关键。若需器件封装图、焊盘尺寸或典型波形,请提供进一步信息以便给出更详细的工程资料。

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.
