L2N7002EM3T5G 产品概述

一、产品简介

L2N7002EM3T5G 是乐山无线电(LRC)推出的一款小信号 N 沟道增强型绝缘栅场效应晶体管(MOSFET),采用超小封装 SOT-723,适合用于低电流、高电压差、空间受限的便携与板上开关场合。单只器件,工作温度范围宽(-55℃ ~ +150℃),可靠性适合工业级应用。

二、主要技术参数

  • 种类:N 沟道增强型 MOSFET
  • 漏源耐压 Vdss:60 V
  • 阈值电压 Vgs(th):2.5 V(典型)
  • 导通电阻 RDS(on):7.5 Ω @ Vgs=5 V、Id=0.05 A
  • 连续漏极电流 Id:115 mA(条件限制下)
  • 功耗 Pd:150 mW
  • 输入电容 Ciss:50 pF @ 25 V
  • 反向传输电容 Crss:5 pF
  • 封装:SOT-723(超小型)
  • 数量:1 只/件

三、关键特性与优势

  • 体积极小,便于高密度 PCB 设计与微型化产品布局。
  • 耐压 60 V,可承受多种中低压开关场景的瞬态电压。
  • 低栅电容(Ciss≈50 pF)有利于快速开关、减少驱动能量,适合与 MCU 或逻辑电平直接驱动。
  • 设计用于小电流应用,静态功耗低,适合信号切换与负载隔离。

四、典型应用

  • MCU/数字电路的低侧开关与负载驱动(小电流继电器、LED、传感器断电等)。
  • 电平移位、信号复用与保护(作为开漏输出或级联保护元件)。
  • 便携设备、通信模块和仪表中对空间与功耗敏感的开关应用。

五、封装与热管理

SOT-723 为超小封装,热阻较大,器件功耗受限(Pd=150 mW)。在实际使用中,应注意:

  • 尽量保持 VDS 较低以减少导通时的功耗(P = I^2·RDS 或 P = VDS·ID)。
  • 若长期工作在较高电流或较高 VDS 条件,应采用降低占空比或散热铜箔扩展的 PCB 设计。
  • 在器件附近留出散热空间,避免与高热源元件贴近。

六、使用建议与注意事项

  • 门极驱动:虽然 Vgs(th)≈2.5 V,但在 3.3 V 驱动下 RDS(on) 会高于标称 5 V 条件下的 7.5 Ω,若要求更低导通阻抗应采用 5 V 驱动。
  • 开关保护:在含有感性负载时建议并联吸收元件或限流,避免 VDS 出现高幅度瞬态冲击。
  • 驱动细节:可在门极串联 50–200 Ω 抑制振荡,并加上 100 kΩ 级别的下拉电阻防止门极浮空。
  • ESD 与焊接:超小封装对静电敏感,建议按管脚防护和推荐回流焊工艺参数操作。
  • 选型注意:若实际工作电流或平均功耗接近器件极限,应选用更大功耗或更低 RDS(on) 的管型。

七、结语与采购

L2N7002EM3T5G 以其小体积、适中的耐压与低栅电容,适合空间受限且电流需求较小的开关与信号应用。在选型时关注驱动电压与热耗限制,合理设计 PCB 散热与外围保护,可获得可靠的长期工作表现。如需批量采购或应用评估,可参考器件完整数据手册以获取曲线、极限值与焊接规范。

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
