AON7140是一款高效能的N沟道场效应管(MOSFET),专为高电流和中等电压应用而设计。它具有46W的功率额定值,支持最多40V的工作电压,以及148A的峰值电流,适用于需要高效率和小体积的电子电路。这款MOSFET采用DFN-8-EP(3.3x3.3mm)的封装形式,满足现代小型化和高集成度电子产品的发展趋势。
高效能: AON7140的设计旨在将开关损耗和导通损耗降到最低,因此可实现更高的能效,适合用于电源管理、电池电源及DC-DC转换器等应用。
低导通电阻: 该部件具有极低的RDS(ON)值,有助于减少在导通状态下产生的功耗。这使得它在高电流应用中表现优异,特别适用于需要快速开关和高负载能力的电路。
小型封装: 采用DFN-8-EP封装,AON7140的尺寸为3.3mm x 3.3mm,非常适合于空间受限但需要高功率的应用场合。这种小型化设计减小了PCB的占用面积,提高了设计灵活性。
优异的热性能: AON7140的热管理设计良好,能够在高负载条件下保持较低的工作温度,增强了系统的稳定性和可靠性。
高频性能: 由于其快速开关特性,AON7140非常适合高频应用,比如高频DC-DC转换、正弦波逆变器和其他需要快速上升/下降时间的场合。
AON7140广泛应用于多种电子及电力设备中,包括但不限于:
在设计基于AON7140的电路时,工程师应关注以下几个方面:
驱动电路: 确保MOSFET的栅极驱动电压足够高,以实现快速开关。同时,考虑到大电流应用,需要适当的驱动电流以减少开关损耗。
散热设计: 由于高功耗可能导致过热,设计时应考虑有效的散热方案,如散热片或风扇,以维持MOSFET的正常工作温度。
PCB布局: 要求良好的PCB设计以减少寄生电感和电阻,优化信号传输。例如,栅极走线应尽量短,避免高频干扰。
AON7140作为一款高性能N沟道MOSFET,其强大的电气参数和小巧的封装使其在现代电子设计中具有重要的应用价值。无论是在电源管理、电动工具还是汽车电子领域,其出色的性能均能满足高效、高性能电路的需求。因此,选择AON7140可以为您的项目带来更好的性能和可靠性。

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.
