1N4148WL2 是扬杰(YANGJIE)生产的一款高压整流二极管,针对需要高耐压和中等整流电流的场合优化设计。器件具有高达1200V的直流反向耐压和1A的整流电流能力,在1A工作点下正向压降为3.4V,反向漏电小(1200V 时典型反向电流仅5µA),适合工业级和高压电源应用。工作结温范围宽(-55℃ 至 +175℃),能够满足高温环境和高可靠性系统的需求。封装为 DFN1006-2(相当于 SOD-882),体积小、焊接可靠,方便表面贴装生产。
1N4148WL2 采用 DFN1006-2(SOD-882)小体积贴片封装,封装优势包括:
在选型时应综合考量工作电压、浪涌环境、工作温度和封装可散热能力。1N4148WL2 以其高耐压、低漏电和宽温度范围,适合需要长期稳定运行的工业及仪器设备。但若工作电流显著高于1A 或存在频繁的大幅浪涌脉冲,应选择额定更高的器件或并联、配合吸收元件进行保护。采购时优先选择正规供应渠道并关注真实出货参数与出厂测试报告,以确保品质与一致性。

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.
