1N4448WS 是晶导微电子推出的一款独立式快恢复/高效率二极管,采用小型 SOD-323W 封装,面向高速开关和信号整流场景。器件在广泛温度范围内工作可靠(结温 Tj:-65℃ 至 +150℃),结合低反向漏电和快速恢复特性,适合对体积、速度和功耗有要求的便携及消费电子产品。
SOD-323W 为小型表面贴装封装,便于自动贴装与回流焊工艺。器件最大耗散功率为 200 mW,热阻相对较大,因此在实际布局中建议增加铜箔面积作为散热路径,避免连续大电流与高环境温度下长期工作导致结温过高。高温下需按厂家温度规格进行功率降额。
器件型号:1N4448WS;品牌:晶导微电子;封装:SOD-323W(独立式)。订货时请参考晶导微电子最新数据手册以获取完整电气特性、封装尺寸及回流焊温度曲线,确保设计与生产一致性。

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.
