AO4485 是华轩阳电子(HXY MOSFET)推出的一款 P 沟道场效应管,封装为 SOP-8,适用于中低压高侧开关和电源管理应用。器件主要参数为:漏源耐压 40V,额定连续漏极电流 13A,最大耗散功率 3W,工作温度范围 -55℃ 至 +150℃,单颗装(数量:1)。在典型栅极驱动电压下具有较低的导通电阻,适合需要低导通损耗的场合。
AO4485 的 Qg 较大(35 nC),意味着在快速开关时对驱动器的瞬时电流要求较高。设计时建议:
SOP-8 的热阻较大,Pd=3W 表明在无额外散热的 PCB 上功耗较容易受限。建议:
总结:AO4485 在 40V 级别提供了较低的导通电阻与适中的开关特性,适合作为高侧开关和电源管理器件。设计时应重点考虑栅极驱动能力与 PCB 散热布局,以充分发挥其低导通损耗优势并确保可靠性。若需更详细的极限参数曲线和封装热阻数据,建议参考华轩阳电子的完整数据手册。

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.
