2N7002KW 产品概述

一、产品简介

2N7002KW 是一款小功率 N 沟道增强型场效应管(MOSFET),由 ElecSuper(静芯微)提供,采用 SOT-323 超小封装,面向空间受限的开关与信号处理场合。器件耐压 60V、连续漏极电流名义值 300mA,适合做低电流、高电压场景下的通断与电平转换等通用用途。

二、主要参数

  • 类型:N 沟道 MOSFET
  • 漏源电压 Vdss:60 V
  • 连续漏极电流 Id:300 mA(器件额定,使用时需综合功耗与散热考量)
  • 导通电阻 RDS(on):1.85 Ω @ Vgs = 10 V
  • 耗散功率 Pd:350 mW(SOT-323 封装,热阻及 PCB 散热影响显著)
  • 阈值电压 Vgs(th):1.6 V @ Id = 250 µA
  • 总栅极电荷 Qg:1.8 nC @ Vgs = 4.5 V
  • 输入电容 Ciss:28 pF;输出电容 Coss:11 pF;反向传输电容 Crss:4 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-323

三、特性与优势

  • 小型化封装:SOT-323 体积小,便于高密度 PCB 布局与便携式设备使用。
  • 高耐压能力:60 V 的 Vdss 使其能在较高电压的开关电路中使用,比常见的低压小信号 MOSFET 更加灵活。
  • 低栅极电荷:Qg 仅 1.8 nC(4.5 V),驱动功率小,适合微控制器直驱或开关频率适中的场合。
  • 低寄生电容:Ciss/Coss/Crss 相对较小,有利于提高开关速度并减少开关损耗与交越干扰。

四、典型应用

  • 低电流高压开关与负载切换(继电器驱动前级、指示灯等)
  • 电平移位与接口驱动(在需要 60 V 耐压但电流不大的场合)
  • 小信号开关、开关矩阵与保护电路
  • 便携式与物联网终端、传感器前端的功率开关

五、使用建议与注意事项

  • 功耗与散热:器件 Pd = 350 mW,封装热阻较大。尽管 Id 名义为 300 mA,但在较高 Vds 下受功耗限制。例如当 Vds = 10 V 时,为不超过 Pd,Id 应限制在约 35 mA(Pd ≥ Vds × Id)。在设计中请计算最大 Vds 与导通损耗,并通过 PCB 铜箔散热或降低电压降来保证安全工作。
  • 驱动电压:RDS(on) 以 Vgs = 10 V 时测得 1.85 Ω,若驱动电压低于 10 V(如 3.3 V 或 4.5 V),实际 RDS(on) 会更高,导通损耗增加。建议根据系统驱动能力调整尺寸或并联器件。
  • 驱动与开关:虽 Qg 较小,但在高速开关时仍建议串联小阻(10–100 Ω)以抑制振荡并限制瞬态电流;必要时并联栅极下拉电阻以确保关断。
  • ESD 与静电防护:栅极敏感,装配与测试时注意静电保护。
  • 可靠性:工作温度范围宽,适应工业级环境;但长期高温与高功耗运行会缩短寿命,应保证适当的热裕量。

六、封装与检验

2N7002KW 采用 SOT-323 小型封装,适合自动贴装与高密度 PCB。采购与生产验收时建议核对封装尺寸、标识、完整数据手册与批次报告,必要时做样片测试(导通电阻、阈值、漏电流与耐压测试)以确认性能一致性。

总结:2N7002KW 是一款面向小信号、高耐压、低功耗场景的通用 N 沟 MOSFET,特点为小体积、低栅极电荷和较高耐压。合理评估驱动条件与热管理后,可在便携设备、接口驱动与高压低流应用中发挥良好作用。

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
