东芝SSM3K72KFS,LF(T) N沟道场效应管产品概述

东芝推出的SSM3K72KFS,LF(T)是一款专为小功率开关与信号控制设计的N沟道MOSFET,采用SOT-416-3超小型封装,具备宽温度范围、低导通损耗等核心特点,适用于便携电子、工业控制及汽车辅助电路等场景。

一、产品基本信息

SSM3K72KFS属于单管N沟道MOSFET,由东芝半导体生产,定位为低电压小电流控制开关,可替代传统继电器或三极管,实现更高效、更紧凑的电路设计。

二、核心电气参数详解

该器件的关键参数直接决定了应用边界与性能表现,具体如下:

1. 电压与电流能力

  • 漏源击穿电压(Vdss):60V,满足12V/24V等低电压系统的耐压需求,避免反向电压损坏;
  • 连续漏极电流(Id):300mA,支持小功率负载(如LED、小电机、传感器)的长期稳定驱动;
  • 功率耗散(Pd):150mW,结合导通电阻计算,100mA负载下导通损耗仅约10mW,发热极小。

2. 导通特性

  • 导通电阻(RDS(on)):1.05Ω@Vgs=10V、Id=100mA,低导通电阻可降低导通损耗,提升能效;
  • 阈值电压(Vgs(th)):2.1V@Id=250uA,可直接由3.3V/5V MCU驱动,无需额外栅极驱动电路,简化设计。

3. 开关特性

  • 输入电容(Ciss):40pF@Vds=10V,低电容值使开关切换时间在微秒级,满足快速信号切换需求;
  • 反向传输电容(Crss):1.3pF@Vds=10V,减少米勒效应影响,进一步提升开关速度;
  • 栅极电荷(Qg):600pC@Vgs=30V,低电荷量降低驱动功耗,适合电池供电的便携设备。

4. 温度特性

工作温度范围为**-55℃~+150℃**,覆盖工业级与汽车级环境(如汽车发动机舱、工业低温车间),可靠性强。

三、封装与可靠性

SSM3K72KFS采用SOT-416-3封装,尺寸仅约2.3×1.6×1.1mm(典型值),属于超小型表面贴装封装,可大幅节省PCB空间,适配便携设备的紧凑布局。

东芝成熟的半导体工艺确保了器件长期可靠性:宽温度范围下导通电阻变化小,可稳定工作于 harsh环境。

四、典型应用场景

结合参数特点,该器件主要应用于以下场景:

  1. 便携电子设备:智能手机耳机接口切换、智能手表电源管理模块、蓝牙耳机信号开关,利用小封装与低功耗提升续航;
  2. 工业控制:传感器信号选择开关、低功率继电器替代(如PLC小信号输出)、小型电机驱动,宽温度范围满足工业需求;
  3. 消费电子:LED小夜灯开关、音频电路通道切换、充电器辅助开关,低导通损耗提升能效;
  4. 汽车辅助电路:胎压监测系统(TPMS)信号控制、仪表盘背光驱动、车载USB电源开关,适配汽车-40℃~+85℃环境。

五、选型优势总结

与同类小功率MOSFET相比,SSM3K72KFS的核心优势包括:

  • 设计简化:低阈值电压可直接由MCU驱动,无需额外电路;
  • 空间节省:超小封装适配高密度PCB;
  • 能效优异:低导通电阻+低栅极电荷,损耗极低;
  • 环境适应:宽温度范围覆盖工业与汽车应用;
  • 可靠性高:东芝工艺确保长期稳定工作。

该器件是小功率开关与信号控制场景的高性价比选择,可有效替代传统器件,提升电路紧凑性与能效。

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
