基本信息
AO3413 是一款高性能的 P 沟道场效应晶体管(MOSFET),专为低功耗应用设计。该 MOSFET 显示出优越的电气性能和可靠性,使其成为现代电子设计中不可或缺的元件之一。AO3413 的关键参数包括:漏源电压(Vdss)为 20V、连续漏极电流(Id)为 3A、栅源极阈值电压为 1V(@ 250μA),以及在 3A、4.5V 时的漏源导通电阻为 97mΩ。这一系列标准使得 AO3413 能够在多个应用领域中展现卓越性能。
电气特性
漏源电压 (Vdss): AO3413 的最大漏源电压为 20V,能够处理多种低压电路。该参数使得此 MOSFET 可以在多种电源条件下稳定工作,同时避免因电压过高而导致的损坏。
连续漏极电流 (Id): 在 25°C 时,AO3413 的连续漏极电流为 3A,显示出其在高电流应用中的能力。这一特性使其能够适应需要较大电流的负载,如马达驱动和电源管理电路。
栅源极阈值电压: AO3413 的栅源极阈值电压为 1V @ 250μA,这表明该 MOSFET 可以在相对较低的栅源电压下开启,从而提高电路的整体效率,减少开关损耗。
漏源导通电阻: 该器件在 3A、4.5V 下的漏源导通电阻为 97mΩ,低导通电阻能够显著降低能量损耗,减少热量生成,进而提升整体系统的效率。
最大功率耗散: AO3413 的最大功率耗散为 1.4W(在环境温度为 25°C 时),这意味着在应用中充分考虑散热设计,以确保 MOSFET 始终在其安全工作区域内运行,避免过热。
封装和品牌
AO3413 采用 SOT-23-3 封装,这种小型封装不仅便于 PCB 上的布局,节省空间,还适合于自动化焊接工艺,适应大规模生产的需求。此款 MOSFET 由 AOS(AOSMD)公司生产,AOS 是在 MOSFET 领域具有较强影响力的品牌,凭借其卓越的产品质量和技术支持,深受全球客户的信赖。
应用场景
AO3413 由于其独特的电气特性,非常适用于以下几个场景:
开关电源: 由于其较低的泄漏电流和导通电阻,以及较高的功率效率,AO3413 可以成为开关电源设计的理想选择,帮助优化能量转换。
马达控制: 当控制电流需要在负载与电源之间迅速切换时,AO3413 能够提供高效的导通和关断性能,适用于各种马达驱动应用。
负载开关: 在需要高效电源管理的应用中,AO3413 可以用作负载开关,提供稳定的连接与断开控制。
电池管理系统: AO3413 的低导通电阻和较低的栅压要求使其成为电池管理系统(BMS)的理想选择,能够有效延长电池的使用寿命并提高整体系统效能。
总结
综上所述,AO3413 是一款性能卓越的 P 沟道 MOSFET,凭借其高电流、低导通电阻及紧凑的封装设计,适用于广泛的电子应用。无论是用于开关电源、马达控制还是电池管理系统,AO3413 都展现出其优异的稳定性和可靠性,是现代电子设计中值得信赖的组件。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
