2N7002KT N沟道MOSFET产品概述

一、基本信息

2N7002KT是CBI(创基)品牌推出的N沟道增强型MOSFET,采用SOT-523-3小型表面贴装封装,产品已通过校验,具备稳定可靠的性能表现。该器件针对低压小电流应用场景优化,平衡了尺寸、功耗与开关特性,适用于多种便携式及工业级小型电路设计。

二、关键电参数与特性分析

1. 电压与电流核心参数

  • 漏源击穿电压(Vdss):60V
    可承受中等幅度的电压波动,避免过压损坏,适配12V/24V等低压系统的电压裕量需求(如车载辅助电路、工业传感器供电)。
  • 连续漏极电流(Id):340mA
    能稳定驱动小型负载(如微电机、LED阵列、低功耗传感器),满足大多数便携式设备的电流需求(如智能手环的振动电机、蓝牙耳机的状态LED)。
  • 阈值电压(Vgs(th)):2.5V(@Id=1mA)
    与主流MCU(3.3V/4.5V逻辑电平)的驱动能力完全适配,无需额外升压电路即可可靠开启,降低系统设计复杂度。

2. 导通与损耗特性

  • 导通电阻(RDS(on)):5.3Ω(@Vgs=4.5V)
    在典型驱动电压下保持较低导通损耗,可减少负载供电时的电压降与功率损耗(如LED驱动时避免亮度衰减),提升系统效率。
  • 耗散功率(Pd):150mW
    结合小型封装的散热能力,能稳定工作在额定功率范围内,避免过热失效(适合连续工作的小型开关场景)。

3. 电容特性与开关性能

  • 输入电容(Ciss):40pF、反向传输电容(Crss):10pF、输出电容(Coss):30pF
    低电容值有助于提升开关速度,减少信号延迟,适配高频信号切换或脉冲控制场景(如PWM调光、高速信号通道切换)。

4. 宽温工作范围

  • 工作温度:-55℃~+150℃
    覆盖工业级与部分汽车级场景的温度需求,可在极端环境(如低温户外、高温设备内部)下稳定运行,可靠性突出。

三、封装与可靠性设计

2N7002KT采用SOT-523-3封装,尺寸紧凑(典型尺寸约1.6mm×1.0mm×0.8mm),适合高密度PCB布局,完美适配便携式电子设备(如智能手表、蓝牙耳机)的小型化设计要求。同时,CBI品牌的校验流程确保了器件在长期使用中的稳定性,降低了故障风险。

四、典型应用场景

1. 便携式电子设备

  • 智能手机、智能手表、蓝牙耳机等产品中的电源开关、信号切换(如音频通道切换)、LED背光电平控制,利用小型封装与低功耗特性适配设备的紧凑空间。

2. 小型电源管理

  • 低功率DC-DC转换电路的辅助开关、电池保护电路的电流检测开关,借助低导通电阻减少损耗,提升电池续航。

3. 工业传感器接口

  • 工业温度、压力传感器的信号放大/切换电路,宽温范围适配现场极端环境,稳定传输微弱信号。

4. 微电机控制

  • 小型玩具电机、智能门锁微电机的驱动控制,340mA电流满足微电机的启动与运行需求。

五、产品优势总结

2N7002KT在同类器件中具备以下核心优势:

  • 尺寸紧凑:SOT-523-3封装节省PCB空间,适配小型化设计;
  • 驱动适配:阈值电压与主流MCU逻辑电平匹配,无需额外驱动电路;
  • 宽温可靠:-55℃~+150℃范围覆盖多场景应用,可靠性高;
  • 损耗较低:低导通电阻减少功率损耗,提升系统效率;
  • 品牌保障:CBI创基的校验通过,质量稳定可靠。

该器件凭借均衡的性能与高适配性,成为低压小电流开关/控制场景的优选方案。

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
