AO3402 是一款由 GOODWORK(固得沃克)品牌生产的 N沟道场效应管(MOSFET),采用紧凑的 SOT-23 封装。该器件设计用于各种高性能电子设备,特别适合需要低导通电阻和高效能的应用场景。
AO3402 具有非常低的导通电阻(RDS(on)),仅为 110mΩ @ 2.5V, 2A。这意味着在开启状态下,器件会产生很少的热量和能量损失,提高系统的整体效率和可靠性。
该器件支持高达 4A 的连续漏极电流,这使得它适用于需要处理较大电流的应用,如电源管理、驱动器和开关电路。
AO3402 的工作温度范围从 -55℃ 到 +150℃,这使得它能够在极端环境下保持稳定运行,适用于各种工业、汽车和消费电子产品。
阈值电压为 600mV @ 250uA,这意味着该器件可以在较低的栅极驱动电压下开启,减少系统的总体能耗。
采用 SOT-23 封装,AO3402 非常适合空间有限但需要高性能的应用场景。这种紧凑的设计使得它可以轻松集成到各种小型电子设备中。
AO3402 可以用于各种电源管理应用,如 DC-DC 转换器、电池管理系统和功率因数校正(PFC)电路。其低导通电阻和高连续漏极电流能力使得它特别适合这些高效能需求的场景。
该器件常用于驱动器和开关电路中,例如驱动 LED 灯、电机或其他负载。其快速开关时间和低热生成特性确保了系统的高效运行和长寿命。
由于其宽工作温度范围,AO3402 也非常适合用于汽车电子系统,如启动系统、燃油喷射系统等。在这些环境中,器件需要能够在极端温度下可靠运行。
在工业控制领域,AO3402 可以用于控制和驱动各种设备,如伺服电机、步进电机等。其高可靠性和耐久性使得它成为这些应用的理想选择。
尽管 AO3402 具有低导通电阻,但在高频或高电流应用中仍需要进行适当的热管理。确保器件有足够的散热路径,以避免过热导致的故障。
由于阈值电压较低,需要确保栅极驱动电路能够提供足够的驱动电压,以确保器件完全开启。同时,避免过高的栅极电压以防止损坏。
在设计时应考虑到电磁兼容性(EMC),确保系统不会受到电磁干扰的影响。使用适当的滤波和屏蔽措施可以帮助减少干扰。
AO3402 是一款高性能 N沟道场效应管,通过其低导通电阻、宽工作温度范围和高连续漏极电流能力,成为各种电子设备中的理想选择。无论是在电源管理、驱动器还是工业控制等领域,AO3402 都能提供出色的性能和可靠性。通过合理的设计和使用注意事项,可以充分发挥出该器件的优势,提高系统的整体效率和可靠性。

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.
