S-LP03N060TZHG 产品概述

一、产品简介

S-LP03N060TZHG 是乐山无线电(LRC)推出的一颗 P 沟道增强型 MOSFET,单片封装 SOT-223,额定漏—源电压 60V,连续漏极电流 2.8A。该器件适合中低功率的高侧开关、负载保护与电源管理场合,兼顾导通损耗与开关性能,适用于需要 P 沟道便捷驱动的电路设计。

二、主要电气参数

  • 类型:P 沟道 MOSFET(增强型)
  • 漏源电压 Vdss:60V
  • 连续漏极电流 Id:2.8A
  • 导通电阻 RDS(on):170mΩ @ |VGS|=10V;200mΩ @ |VGS|=4.5V
  • 阈值电压 VGS(th):3V(@ 250µA,标注为阈值幅值)
  • 总栅极电荷 Qg:3.6nC @ 4.5V
  • 输入电容 Ciss:366pF;反向传输电容 Crss:17pF;输出电容 Coss:24pF
  • 功耗 Pd:1.7W
  • 工作温度范围:-55℃ ~ +150℃
  • 封装:SOT-223;品牌:LRC(乐山无线电)

三、性能与应用要点

  • 导通损耗评估:在最大额定电流 2.8A 下,按 RDS(on)=200mΩ 计算,导通功耗约 P = I^2·R ≈ 1.57W;接近器件 Pd=1.7W 极限,说明在满流条件下需重视散热。若以 RDS(on)=170mΩ(|VGS|=10V)计算,功耗降至约1.33W。
  • 驱动要求:为了获得较低的 RDS(on),推荐使用较大幅值的栅源电压(参考 10V),若仅能提供逻辑电平驱动(4.5V),RDS(on) 仅略有上升。栅极电荷 Qg=3.6nC 表明驱动电流与开关速度呈线性关系,设计门极驱动时需考虑充放电损耗。
  • 开关特性:适中 Ciss/Crss 值使其在开关频率不太高的 DC-DC 或开关控制中表现良好,高频应用需评估开关损耗。

四、热设计与封装建议

  • SOT-223 封装散热能力有限,建议在 PCB 上扩展散热铜箔(热垫与多层铜)并靠近大面积接地/电源平面以降低结—焊盘温升。
  • 在靠近器件的铜箔上增加过孔与散热过孔,可显著降低热阻。若实际工作电流长期接近 2.8A,应考虑并联 MOSFET 或选用更大封装器件以保证可靠性。

五、典型应用场景与参考建议

  • 高侧开关与电源逆向保护(利用 P 沟道便于将源接至正电源)。
  • 电池供电系统和便携设备中的功率管理、负载断开。
  • 低至中频 DC-DC 拓扑的低端开关或软开关实现。
  • 设计时根据系统电源电压规划栅极驱动电平,保证 |VGS| 足以达到所需 RDS(on)。

六、注意事项与选型提示

  • 阈值电压以 |VGS|≈3V(@250µA)标注,实际导通程度受温度与电流影响,尽量不要仅靠阈值来判断导通能力。
  • 当工作电流接近器件额定值时,优先考虑散热设计或并联分担。
  • 如果系统需在高频或大电流下长期工作,建议评估更低 RDS(on) 或更大功耗等级的替代器件。
  • 采购型号:S-LP03N060TZHG(LRC,SOT-223),下单时确认封装与批次,便于获得稳定参数。

如需基于具体工作电压与负载条件的损耗计算、PCB 布局建议或替代器件推荐,可提供系统电压与开关频率等信息以便进一步优化选型与设计。

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
