3400Q是富海微(HL) 推出的单颗N沟道增强型MOSFET,采用SOT-89-3L 小型表面贴装封装,核心定位于低电压(≤30V)中等功率场景的开关/驱动应用,具备体积小、效率高、驱动简单等特点。
3400Q的核心参数围绕电压、电流、导通损耗、开关速度四大维度设计,适配主流低电压电路需求:
3400Q采用SOT-89-3L 3引脚表面贴装封装,具备以下特点:
结合参数特性,3400Q主要适用于以下场景:
适配12V/24V系统的降压/升压电路(如车载充电器、移动电源),7A电流能力满足中等功率需求,低RDS(on)降低转换损耗(效率可提升2%-5%)。
用于单节/多节锂电池的保护电路(30V电压覆盖3-6串锂电池),宽温范围适应电动车、储能设备的高低温环境,快速开关特性提升保护响应速度。
驱动小功率直流电机、步进电机(如智能家居电机、玩具电机),7A连续电流满足启动/运行需求,低导通电阻减少电机发热。
用于便携式设备(手机、平板)的电源路径切换,低RDS(on)减少压降(12V系统下7A电流仅产生0.35V压降),易驱动特性兼容MCU直接控制。
适配LED驱动(如背光调节)、射频前端小信号开关,低Qg设计减少开关损耗,提升高频效率。
为确保3400Q稳定工作,需注意以下要点:
3400Q在小封装下实现了**「高电流密度+低损耗+宽温适配」** 的平衡,核心优势包括:
综上,3400Q是一款针对低电压中等功率场景优化的N沟道MOSFET,可满足便携式设备、工业控制、汽车周边等领域的多样化需求。

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.
