LNTK2575LT1G 产品概述
LNTK2575LT1G 是乐山无线电（LRC）推出的一款 N 沟增强型绝缘栅场效应管（MOSFET），采用小型 SOT-23 表面贴装封装，针对低电压、低功耗开关与电平转换应用优化设计。器件在 25V 漏源耐压下可提供最高 700mA 连续漏极电流，适用于便携式电源管理与信号切换场景。
一、主要参数概览
- 类型：N 沟增强型 MOSFET，封装：SOT-23
- 漏源电压 Vdss：25V
- 连续漏极电流 Id：700mA（环境与散热受限条件下）
- 导通电阻 RDS(on)：249mΩ @ Vgs=4.5V
- 栅阈电压 Vgs(th)：1.5V（典型）
- 总栅极电荷 Qg：1.5nC @ Vgs=4.5V
- 输入电容 Ciss：60pF，反向传输电容 Crss：12pF
- 耗散功率 Pd：280mW（需结合 PCB 散热评估）
- 工作温度范围：-55℃ ~ +150℃
二、产品特点与优势
- 低电压等级（25V）适合常见的 3.3V/5V 系统应用，栅极阈值低、有利于逻辑电平驱动。
- 中等 RDS(on) 与较低栅极电荷（1.5nC）兼顾开关损耗与驱动能耗，适合频率不高的开关场合。
- 小封装 SOT-23 节省 PCB 面积，适用于体积受限的便携设备。
- 宽工作温度覆盖工业级要求，可靠性良好。
三、典型应用场景
- 低压电源开关与负载断开（如便携设备电源管理）
- 电平转换器与信号开关（I/O 保护、模拟开关）
- 小功率马达或继电器驱动的前端开关
- 电池保护与充放电路径控制
四、驱动与布局注意事项
- 推荐使用接近系统电平的栅极驱动（如 4.5V）以达到标称 RDS(on)。若仅由 3.3V 驱动，应验证导通电阻与散热是否满足要求。
- 低 Qg 有利于 MCU 直接驱动，但仍建议在驱动线加入阻尼电阻以抑制电磁干扰和振铃。
- PCB 布局应保证漏极-源极回流路径的短而粗，增大铜箔面积以改善散热；SOT-23 的热阻较高，器件功耗受限于 PCB 散热能力。
五、热与可靠性提示
- 标称耗散功率 280mW 为参考值，实际可用功率受 PCB、环境温度与封装散热影响较大。高于该功率时需保护或选择更大封装器件。
- 工作温度可到 +150℃，但长期在高温下工作会缩短寿命，建议保证器件结温在安全范围内并预留热裕量。
六、封装与采购信息
- 封装：SOT-23（表面贴装，适合自动贴装生产）
- 品牌：LRC（乐山无线电）
- 型号：LNTK2575LT1G，单只采购或小批量用途适合该型号。
使用该器件时建议在样机阶段验证在目标电压、频率及环境温度下的导通损耗和结温，确保满足系统可靠性与寿命要求。若需更低 RDS(on) 或更高功率能力，可考虑更大封装或低阻型号。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
