S80N04D 是富海微(HL)推出的一款高电流、低导通电阻的N沟增强型功率MOSFET,适用于中低压、高效率开关电源与功率管理场景。器件额定漏源电压为40V,封装为小尺寸高导热的PDFN-8L(3×3),在尺寸受限但需要较大导流能力的应用中具备明显优势。
PDFN-8L(3×3)封装在小体积下提供较好的热路径,但要发挥65.8 W的耗散能力,必须配合合理的PCB散热设计。推荐做法包括:在焊盘下和周围使用大面积铜箔、充分的过孔阵列连接到背面散热层、并保证良好的焊接工艺与热阻控制。实际允许的连续电流受焊盘、PCB铜厚、环境温度及散热条件影响,选型时应按系统热仿真或经验裕量计算。
总结:S80N04D 以40V 耐压、低RDS(on) 和高电流承载能力为主要优势,适合要求高效率与小封装空间的功率开关应用。为获得最佳性能,请结合实际PCB散热设计与驱动电路优化使用。若用于关键系统,请参阅完整数据手册并进行热稳态与开关损耗验证。

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.
