XR20N03D是新锐半导体(XNRUSEMI)推出的低压大电流N沟道增强型MOSFET,主打“小封装、低损耗、高开关效率”三大核心特性,针对便携电子、低压电源管理等对空间和性能要求苛刻的场景优化设计,可覆盖12V/5V等主流低压系统的大负载驱动需求。
导通电阻(RDS(on))=15mΩ@10V Vgs、5A Id:这是低压MOSFET的核心性能指标——低RDS(on)意味着电流通过时压降更小(如5A电流下仅0.075V压降),对应功率损耗仅0.375W,可大幅降低系统发热,提升电源转换效率。
XR20N03D采用PDFN-8L(3.3×3.3mm)超小型封装,相比传统TO-252封装体积缩小约70%,可显著节省PCB空间,适配智能手机、智能手表等便携设备的高密度布局需求。
同时,封装的热阻抗设计支持最大耗散功率(Pd)=5.5W(25℃环境下),配合PCB散热铜箔可有效控制结温,满足连续大电流工作的散热要求。
XR20N03D凭借“小封装、低损耗、宽温可靠”的特性,成为低压大电流应用场景的高性价比选择,覆盖消费电子、工业控制等多领域产品设计。

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.
