IRLHS6242TRPBF 产品概述

一、概述

IRLHS6242TRPBF 是一颗小尺寸、高性能的 N 沟道功率 MOSFET,适合在低压、高效率开关电源与功率分配场景中使用。器件为逻辑电平型,封装为 PQFN-6-EP (2×2),由 Infineon(英飞凌)提供,适合空间受限且对导通损耗有严格要求的移动设备和电源管理应用。

二、主要性能参数

  • 漏源耐压 Vdss:20 V
  • 导通电阻 RDS(on):15.5 mΩ @ Vgs = 2.5 V, Id = 8.5 A
  • 连续漏极电流 Id:12 A
  • 功耗 Pd(器件额定耗散):9.6 W
  • 阈值电压 Vgs(th):1.1 V @ Ig = 10 µA
  • 总栅极电荷 Qg:14 nC @ Vgs = 4.5 V
  • 输入电容 Ciss:1.11 nF
  • 输出电容 Coss:260 pF
  • 反向传输电容 Crss(Coss/栅漏电容):180 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 类型:N 沟道 MOSFET,单片器件(1 个)

三、封装与热特性

PQFN-6-EP (2×2) 提供紧凑的 PCB 占板面积,并带有裸露散热焊盘(exposed pad),便于通过 PCB 铜箔和通孔将热量传导至散热层或散热体。器件额定耗散为 9.6 W,但实际安全热设计需依据 PCB 热阻、铜层面积及通孔数量来评估器件结温,避免长期运行在高结温下影响可靠性。

四、特性与优势

  • 低 RDS(on)(15.5 mΩ @ 2.5 V)表明器件为逻辑电平驱动,适用于 2.5 V 或更高电平的直接驱动,可降低导通损耗,提升转换效率。
  • 中等大小的栅极电荷(Qg = 14 nC @ 4.5 V)在保证快速开关的同时,对驱动器功耗要求适中,利于成本和效率平衡。
  • 较小的 Coss(260 pF)和适中的 Crss(180 pF)有利于降低开关损耗和减轻米勒效应对开关边沿的影响,但在高 dv/dt 环境下仍需注意栅极控制。
  • 宽工作温度范围适合工业级和汽车级周边环境。

五、典型应用

  • 同步整流型降压转换器(synchronous buck)
  • 电源开关与负载切换(load switch)
  • 电池管理与电源分配模块(PMIC)
  • USB/PD 开关、便携式设备电源路径
  • 小型电机驱动与点对点功率转换场景

六、布局与使用建议

  • 将裸露散热焊盘与 PCB 大面积铜箔相连并配合多通孔,以降低结-至-环境热阻。
  • 栅极走线尽量短且阻抗控制良好,栅极与驱动器之间可并联小电阻(例如 2.2–10 Ω)以抑制振铃并减小瞬态电流。
  • 在栅—源之间加上阻值合适的下拉电阻,防止断电或上电瞬态时栅极漂浮导致误导通。
  • 漏—源路径使用短、宽铜迹以降低寄生电阻与电感;在高 dv/dt 场合考虑在能量回收或续流路径上使用 RC 或 TVS 抑制尖峰。
  • 布局时注意将敏感信号和驱动回路与开关回路分隔,减小干扰耦合。

七、使用注意事项

  • 虽为逻辑电平器件,但在需要极低导通损耗或高频切换时,合适的栅极驱动电压(如 4.5 V)可进一步降低 RDS(on) 并缩短开关时间。
  • 器件的脉冲与瞬态能量处理能力需参阅完整数据手册(SOA、能量吸收/浪涌、封装热阻等),在感性负载或高应力开关场合慎重评估。
  • 设计时留意 Crss 对开关瞬态(米勒效应)的影响,必要时配合合适的驱动/缓冲网络以避免误触发或过度应力。

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
