XR120N04T — XNRUSEMI(新锐) 高密度沟槽式 N 沟道 MOSFET 概述

一、产品定位与简介

XR120N04T 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道功率 MOSFET,面向高电流、高效率的开关电源和功率转换应用。器件在 40V 漏源耐压下,提供极低的导通电阻与大电流能力,适用于多数同步降压转换器以及各种功率级开关场合。符合 RoHS 与绿色产品要求,100% 保证 EAS,并通过全功能可靠性认证。

二、关键电气参数(主要规格)

  • 类型:单个 N 沟道 MOSFET
  • 漏源电压 Vdss:40V
  • 连续漏极电流 Id:120A
  • 导通电阻 RDS(on):2.9 mΩ @ Vgs = 10V
  • 阈值电压 Vgs(th):1.7V
  • 总栅极电荷 Qg:110 nC @ 20V
  • 输入电容 Ciss:6.13 nF
  • 输出电容 Coss:401 pF
  • 反向传输电容 Crss(Miller 容):348 pF
  • 耗散功率 Pd:115W(TO-220AB,视散热条件而定)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO-220AB

三、主要特性与优势

  • 低导通损耗:在 10V 栅压下 RDS(on) 仅 2.9 mΩ,可显著降低导通损耗,适合高电流输出设计。
  • 高电流能力:120A 连续电流能力满足大电流开关和低压高电流电源要求。
  • 沟槽型结构:高单元密度设计兼顾低 RDS(on) 与器件稳定性,适用于要求高效率与紧凑功率密度的场合。
  • 完整的电气验证与可靠性:符合 RoHS,100% EAS 保证并具备全功能可靠性认证,适合量产与工业级应用。
  • 通用 TO-220AB 封装:便于散热管理与手工或自动化装配,利于快速原型与小批量生产。

四、典型应用场景

  • 同步降压(buck)转换器:作为高侧或低侧功率开关,兼顾低导通损耗与开关性能。
  • 高电流 DC-DC 电源与分配模块(VRM、POL 模块等)。
  • 汽车电子(车载 12V/24V 系统中的开关电源模块),在 40V 额定下能耐受瞬态尖峰。
  • 电机驱动低压段、功率开关阵列与逆变器的部分功率级。

五、驱动与开关建议

  • 推荐栅极驱动电压:10V,保证 RDS(on) 指标。Vgs(th) 为 1.7V,低门槛便于导通,但为获得最低导通电阻应使用 10V 驱动。
  • 栅极电荷与驱动能力:Qg = 110 nC(@20V)表明器件栅电荷偏大,开关时需较强驱动瞬态电流以实现快速切换。设计驱动电路时应考虑驱动峰值电流能力和驱动损耗。举例:若希望在 50 ns 内完成栅极充放电,平均峰值电流约为 Qg/ts ≈ 2.2 A(参考计算)。
  • Miller 效应注意:Crss = 348 pF,Miller 电容较大,可能在切换瞬间导致栅-漏耦合,需在布局、门极电阻与驱动速度上平衡以避免过度振铃或误触发。建议合理选取门阻并最小化驱动回路的寄生电感。

六、热管理与布局建议

  • 虽然器件 Pd 指定为 115W(TO-220AB),但实际功率耗散高度依赖散热条件与 PCB/散热片设计。针对高功率工作场景,务必使用合适尺寸的散热片并保证良好接触(必要时使用导热垫或绝缘垫)。
  • 布局要点:减小开关回路面积(尤其是漏极—源极回路)以降低寄生电感;栅极回路短且粗,避免长导线引起振荡。若需要,高频旁路电容应靠近器件电源端子布局。
  • 安装注意:TO-220AB 可通过螺栓固定于散热片;若需要电气绝缘,请使用绝缘垫和绝缘螺柱,但需留意导热性能。

七、封装与采购信息

  • 封装:TO-220AB,便于手工焊接与散热片安装。
  • 品牌:XNRUSEMI(新锐)。
  • 适用于需要结合高导通电流与成本效益的设计方案。采购与样片测试前建议索取完整数据手册与可靠性报告以评估在具体工作点下的表现。

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.
