AO3402 是一款由 TWGMC（台湾迪嘉）生产的 N-channel MOSFET，采用 SOT-23 封装设计，广泛应用于各种低电压、高效率的电子电路中。这款 MOSFET 以其出色的性能和紧凑的尺寸，成为了现代电子设计中的重要组成部分。
产品概述
基础特性： AO3402 MOSFET 的主要特性包括较低的导通电阻（R_DS(on)），高速度开关能力，以及较大电流承载能力，使其成为驱动负载的理想选择。典型的导通电阻值在 10V 的栅极驱动电压下其 R_DS(on) 通常在 30 至 60 毫欧之间，从而能够有效减少功率损耗，增强电路的整体效率。
电气特性： AO3402 的最大耗散功率可达到 1.5W，具备较强的热管理性能。同样，其最大漏极电压（V_DS）可达到 30V，使其适用于多种中低导电电压的应用场景。此外，AO3402 的最大漏极电流（I_D）可达到 7.5A，组件能够应对较大的负载，非常适合用于电机驱动、电源管理和其他需要快速开关的应用。
封装与形状： SOT-23 是一种小型表面贴装封装，尺寸约为 2.9mm x 1.3mm。这种小型化设计使 AO3402 适合用于空间要求较高的电路板，并且能够提高板级集成度，为便携式设备、手机、平板电脑以及其他小型电子产品的开发提供了便利。
应用领域
AO3402 能够广泛应用于多个领域，包括但不限于：
电源管理: 在开关电源（SMPS）、DC-DC 转换器及 LED 驱动电路中，AO3402 可以用作开关元件，有助于提高电源转换效率和可靠性。
电机驱动: 由于其高电流承载能力，AO3402 常用于直流电机驱动和步进电机控制，将其应用于各类自动化设备和家用电器中。
信号开关: 作为低压开关元件，AO3402 可以用于控制信号通断，例如在音频设备、射频系统等领域。
负载驱动: AO3402 也适合用于驱动低压负载，如继电器和灯具，能有效降低功耗和提升性能。
性能优势
AO3402 的优势在于其较低的导通电阻及高电流输出能力，这意味着在较高的负载电流下， MOSFET 的发热量相对较低，从而提高了电路的可靠性。其响应时间快，能够在开关频率较高的应用中保持良好的性能。此外，基于 SOT-23 封装的设计，使其能在有限空间内实现更高的电气性能和更好的散热性能。
总结
AO3402 是一款性能卓越的 N-channel MOSFET，凭借其优良的电气特性和小型封装，广泛应用于现代电子产品中。通过选择 AO3402，设计工程师不仅能够实现高效的电源转换和可靠的负载驱动，还能够在设计中提升整体器件部署的灵活性和紧凑性。因此，AO3402 为各种电子应用提供了理想的解决方案。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
