LNTK3043NT5G 产品概述

LNTK3043NT5G 是乐山无线电(LRC)推出的一款低电压、小电流 N 沟增强型 MOSFET。器件适用于开关控制与小功率驱动场合,具有低门极电容、宽工作温度范围及明确的导通电阻参数,便于在便携式与低功耗系统中使用。

一、主要参数概览

  • 类型:N 沟增强型 MOSFET
  • 漏源耐压 Vdss:20 V
  • 连续漏极电流 Id:285 mA(最大)
  • 导通电阻 RDS(on):3.8 Ω @ Vgs = 4.5 V, Id = 255 mA
  • 阈值电压 Vgs(th):1.3 V(测量条件:Id ≈ 250 μA)
  • 输入电容 Ciss:55 pF @ Vds = 10 V
  • 反向传输电容 Crss:7 pF @ Vds = 10 V
  • 损耗功率 Pd:440 mW
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 品牌:LRC(乐山无线电)
  • 封装:未标注(请以正式数据手册为准)

二、器件特性与优势

  • 低阈值电压(约 1.3 V):便于在较低驱动电压下开启,适合与低压逻辑电平配合使用。
  • 典型导通电阻在 4.5 V 驱动下为 3.8 Ω:虽然不是超低 RDS(on),但对几十毫安级负载的开关驱动已经足够。
  • 较小的输入/反向电容(Ciss = 55 pF,Crss = 7 pF):有利于减少切换损耗和降低驱动电荷,对快速开关和高频应用更友好。
  • 宽温度范围:-55 ℃ ~ +150 ℃,适用于工业级环境下的应用。

三、典型应用场景

  • 低功率开关控制:用于驱动小型继电器、LED、传感器等低电流负载。
  • 电平转换与接口保护:在需要将低电压控制信号切换到 20 V 以下负载的场合使用。
  • 电池供电设备:门极驱动电压较低时可实现较好开通,适合便携式装备的功率管理。
  • 通用小信号放大与开关:用于模拟开关、低速信号切换等。

四、设计与使用注意事项

  • 功耗与散热:Pd = 440 mW,器件为小功率级,长时间工作于接近最大电流时需注意温升与散热;建议在 PCB 布局中为器件提供合理的铜箔散热路径或降低工作电流。
  • 驱动电压选择:RDS(on) 数据给出的是在 Vgs = 4.5 V 条件下的测量值;若在 2.5 V 或更低电压下驱动,导通电阻会显著上升,应评估实际导通损耗。
  • 工作电压范围:Vdss = 20 V,适用于低压场合。避免在超过额定电压下工作以防击穿。
  • 样片与封装:当前信息未标注封装类型,选型时请以官方数据手册或供应商标注为准,确认引脚排列与热阻参数。
  • 门极静电防护:与所有小型 MOSFET 一样,建议在装配与测试过程中注意静电防护(ESD),以免损坏门极氧化层。

五、典型电气特性参考(设计时需验证)

  • 阈值电压 Vgs(th):约 1.3 V(Id ≈ 250 μA)
  • 导通电阻 RDS(on):3.8 Ω @ Vgs = 4.5 V, Id = 255 mA
  • 输入电容 Ciss:55 pF @ Vds = 10 V
  • 反向传输电容 Crss:7 pF @ Vds = 10 V

以上为器件的主要电气特性参考,实际设计中应依据完整数据手册进行仿真与验证。

六、选型建议与替代考虑

  • 若目标应用需要更低的导通电阻或更高的连续电流,应考虑功率更高、RDS(on) 更低的 MOSFET。
  • 对于仅需 1.8 V 或更低门极驱动的场合,建议验证 Vgs 下的 RDS(on) 特性,或选用专为低压驱动优化的逻辑级 MOSFET。
  • 在需要明确封装和热阻参数时,请向 LRC 获取正式数据手册或样品确认。

总结:LNTK3043NT5G 是一款面向低压、低功耗开关应用的 N 沟 MOSFET,适合驱动几十毫安级负载及电平转换场景。在选型与电路设计时需重视功耗、驱动电压和封装散热条件,建议参照厂方完整数据手册做最终验证。

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.
