50P03D是富海微(HL)推出的一款低电压大电流P沟道增强型MOSFET,针对导通损耗、开关速度及空间尺寸优化设计,具备宽温适应性与高可靠性,采用DFN3x3小封装,可广泛应用于便携电子、低压电源、工业控制等场景,是替代传统继电器或高损耗开关器件的理想选择。
50P03D定位于低压直流系统的功率开关器件,核心覆盖12V/24V常见电压平台,以“大电流承载+低损耗+小型化”为设计目标,解决传统开关器件在小型化设备中效率低、发热大的痛点。其主要应用方向包括:
采用DFN3x3封装(无引脚扁平封装),尺寸仅3.0mm×3.0mm×0.8mm,相比传统TO-252封装体积缩小约60%,适配便携式设备、高密度电路板的小型化布局。
DFN封装通过裸露焊盘直接连接PCB散热铜箔,热阻(R_{th(j-a)})约35℃/W,可快速将器件热量传递至系统,保障5.2W功率下的稳定工作。
50P03D相比同类30V/50A P沟道MOSFET,具备以下核心竞争力:
50P03D凭借低损耗、快开关、宽温及小型化特性,为低压大电流场景提供了高性价比的功率开关解决方案,助力系统实现高效、小型化与高可靠性设计。

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.
