FS3400 N沟道MOSFET产品概述

FS3400是FOSAN(富信)推出的一款N沟道增强型MOSFET,采用超小型SOT-23-3L封装,专为低电压、中小功率场景设计,兼具高电流密度与低功耗特性,可满足便携电子、电源管理等领域的集成需求。

一、产品基本属性

FS3400为单管N沟道MOSFET,核心定位是小封装高电流密度器件:

  • 品牌:FOSAN(富信)
  • 类型:N沟道增强型
  • 封装:SOT-23-3L(超小型3引脚封装)
  • 适用场景:低电压(≤30V)中小功率电路

二、核心电气参数详解

FS3400的电气参数针对低电压应用优化,关键指标清晰适配实际场景:

  1. 耐压与电流能力:最大漏源电压(Vdss)为30V,覆盖5V、12V、24V等常见低电压系统;连续漏极电流(Id)达5.8A,在SOT-23-3L小封装下实现较高电流密度,满足中小负载驱动需求。
  2. 导通电阻与功耗:栅源电压(Vgs)为10V时,导通电阻(RDS(on))仅40mΩ,低阻特性可显著降低导通损耗;配合最大耗散功率(Pd)1.5W,能有效控制器件发热,避免系统过热。
  3. 驱动兼容性:阈值电压(Vgs(th))为2V(漏极电流Id=250uA时),兼容3.3V、5V等常见控制电压,无需额外升压电路即可驱动,简化系统设计流程。
  4. 电容与可靠性:输入电容(Ciss)545pF、输出电容(Coss)66pF,参数匹配中小功率开关场景的速度需求;工作温度范围覆盖-55℃至+150℃,满足工业级或极端环境下的长期可靠性。

三、封装与引脚说明

FS3400采用SOT-23-3L超小型封装,尺寸紧凑(典型尺寸约2.9×1.6×1.1mm),便于PCB高密度集成(如便携设备主板、小型模块)。引脚布局遵循行业通用规范,通常定义为:

  • 引脚1:栅极(G)——接收控制信号
  • 引脚2:漏极(D)——连接负载或电源端
  • 引脚3:源极(S)——接地或参考电位端

封装采用耐高温塑料材质,耐温性与机械强度符合行业标准,可通过回流焊、波峰焊等常规工艺贴片,适配自动化生产需求。

四、典型应用场景

FS3400的参数特性使其精准匹配以下低电压中小功率场景:

  1. 便携电子设备:智能手机、平板电脑、智能手环等的电源路径开关、电池保护电路(过流/过压保护)。
  2. 小型DC-DC转换器:12V转5V、5V转3.3V等降压电路的同步整流管或开关管。
  3. 负载开关:低功耗设备的电源通断控制(如USB端口、外设供电)。
  4. 小型电机驱动:玩具电机、小型直流风扇、微型泵等的驱动电路。
  5. LED驱动:小功率LED阵列(如指示灯、背光)的恒流/恒压驱动。

五、性能优势总结

FS3400相比同封装同等级MOSFET,具备以下核心优势:

  1. 高电流密度:SOT-23-3L小封装下实现5.8A连续电流,节省PCB空间的同时满足负载需求。
  2. 低功耗设计:40mΩ低导通电阻降低导通损耗,1.5W耗散功率控制发热,延长系统寿命。
  3. 宽温可靠性:-55℃~+150℃工作温度范围,适配户外、工业便携等极端环境。
  4. 驱动兼容性强:2V阈值电压兼容3.3V/5V控制,无需额外驱动电路,简化设计成本。
  5. 易集成性:超小型封装适合高密度PCB布局,匹配便携设备小型化趋势。

综上,FS3400是一款专为低电压中小功率场景优化的N沟道MOSFET,以高电流密度、低功耗、宽温特性成为便携电子、电源管理等领域的高性价比选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
