SSM3K7002CFU,LF(T) 是东芝(TOSHIBA)推出的一款N沟增强型场效应管(MOSFET),面向低功耗、小电流的开关与控制应用。器件耐压60V,适合中低电压系统中的开/关控制、负载隔离和保护电路。封装为USM,体积小,便于在空间受限的便携或消费电子产品中使用。
器件特点包括耐压较高、器件电容较小、封装小巧,适合快速开关及节能场合。
阈值电压约2.1V,表明器件在较低门极电压下即可进入导通区,但规格化导通电阻是在VGS=10V下测得,实际在逻辑电平(如3.3V或4.5V)驱动时导通性能会下降,应根据负载电流选型。栅极电荷标称350 pC(@4.5V),在快速切换场合需考虑驱动能力与开关损耗,建议使用合适驱动器或缓冲级以控制上升/下降斜率,降低开关应力。
器件输入/输出电容较小(Ciss 17 pF,Coss 3 pF,Crss 0.7 pF),有利于减少寄生能量与提高开关速度,但仍需注意寄生振荡与PCB走线的布置。
额定耗散功率700 mW,在实际电路中应评估工作点与环境温度。由于USM小型封装散热能力有限,建议:
SSM3K7002CFU,LF(T) 适合需要60V耐压但电流要求不高的开关应用,其小封装和较低电容有利于节约空间与改善开关性能。选型时应结合实际工作电压、负载电流及驱动电平,关注栅极驱动能力与散热设计,确保在安全工作区内运行以获得稳定可靠的性能。若需更低的导通损耗或更高电流能力,可在器件家族中选择更低RDS(on)或大封装型号。

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.
