T2N7002AK-ES 产品概述

一、主要参数

T2N7002AK-ES 是一颗小信号 N 沟道增强型 MOSFET,适用于低功耗开关与驱动应用。主要参数如下:

  • 漏源耐压 Vdss:60 V
  • 连续漏极电流 Id:300 mA(受封装散热限制)
  • 导通电阻 RDS(on):1.85 Ω @ Vgs = 10 V
  • 功耗 Pd:350 mW(封装热阻相关,实际需考虑 PCB 散热)
  • 阈值电压 Vgs(th):1.6 V @ ID = 250 μA
  • 栅极电荷 Qg:1.8 nC @ Vg = 4.5 V
  • 输入电容 Ciss:28 pF;反向传输电容 Crss:4 pF;输出电容 Coss:11 pF
  • 类型:N 沟道;封装:SOT-23;品牌:ElecSuper(静芯微)

二、特性与优势

  • 高耐压(60 V),适合小功率高压开关场合。
  • 低栅极电荷(Qg 1.8 nC),在 3.3V/5V 驱动下开关损耗较小,适合 MCU 或逻辑电平直接驱动。
  • 小封装 SOT-23,便于 PCB 高密度布局与自动化贴装。
  • 阈值电压适中,容易在低电流应用中实现可靠导通与关断。

三、典型应用

  • 微控制器驱动的小负载开关(LED、继电器驱动器前级、传感器供电开/关)
  • 电平移位与信号缓冲、负载下拉或限流保护
  • 小电流电源管理、便携设备的功率路径切换
  • 高压小电流开关场合(例如 24V 系统的低功耗控制)

四、使用注意事项

  • 标称 Id 为 300 mA,但 SOT-23 封装热阻较大,若长时间流过接近额定电流需做好 PCB 散热或降低工作电流以避免过热。
  • RDS(on) 标注为 10V 条件下的值,在 3.3V 或 4.5V 驱动时导通电阻会明显增大,应按实际测量或保守估计用于功耗计算。
  • 开关瞬态中 Crss(米勒电容)会影响开关速度与电压应力,布局应尽量缩短栅到漏/源回路的寄生电感与路径。
  • ESD 与浪涌保护视具体电路而定,必要时在栅极或漏极并联 TVS 或 RC 抑制网络。

五、封装与可靠性

  • SOT-23 小型封装,适合表面贴装加工。
  • 推荐在布局时保证良好的散热铜面积与短回流路径,以利热量扩散。
  • 适合符合消费类与工业类一般工作环境,若用于严苛环境应参考厂方完整数据手册和可靠性测试报告。

六、典型电路与选型建议

  • 若用于 3.3V 逻辑开关低电阻负载,建议验证导通电阻与功耗;对连续电流在几十毫安以上的场合,优先考虑更低 RDS(on) 或更高 Pd 的器件。
  • 作为开关元件示例:低侧开关把源接地,漏接负载至电源;栅极直接由 MCU 驱动(GPIO)并在栅与地间加 100 kΩ 下拉确保上电态稳定。
  • 若需频繁高速开关,可根据 Qg 与 Ciss 计算驱动电流并加装合适驱动器或阻尼器以降低 EMI。

总结:T2N7002AK-ES 以其 60V 耐压、低栅极电荷和 SOT-23 小体积特点,适合各类低功耗、高压小电流的开关与驱动场景。设计时应综合考虑驱动电压、实际导通电阻与封装散热限制以确保长期可靠工作。

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
