XR100N03 产品概述

一、产品简介

XR100N03 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道 MOSFET,专为高效率同步降压转换器与大电流开关应用设计。器件采用 TO252-3L(DPAK)封装,额定漏源电压 Vdss = 30V,连续漏极电流 Id = 100A,适合低压高电流电源前端与功率级场合。

二、主要特性

  • 漏源电压:30V,满足 12V/24V 系统的开关需求。
  • 连续漏极电流:100A,适用于高电流软开关或同步整流。
  • 导通电阻:RDS(on) = 4.7mΩ @ Vgs=10V,低导通损耗,提升系统效率。
  • 阈值电压:Vgs(th) = 2.5V(典型),需足够门极驱动以达到低 RDS(on)。
  • 栅极电荷:Qg = 45nC(@15V),开关时需较大瞬时驱动电流。
  • 输入电容/反向传输电容:Ciss = 2.1nF,Crss = 282pF,影响开关过渡与米勒效应。
  • 功耗与温度:耗散功率 Pd = 80W,工作温度范围 -55℃ ~ +175℃。
  • 环保与可靠性:符合 RoHS/绿色产品要求,100% 保证 EAS,并具备完整功能可靠性认证。

三、典型应用

  • 同步降压转换器(主开/同步整流)
  • DC-DC 转换电源前端与负载开关
  • 汽车与工业 12V/24V 电源管理(基于器件温度与热设计)
  • 高性能电机驱动与功率模块

四、设计与驱动建议

  • 驱动电压:为达到标称 RDS(on),建议采用 10V 门极驱动;在 5V 逻辑驱动下导通损耗会明显增加,应采用专用门极驱动器或提升栅极电压。
  • 门极驱动能力:Qg=45nC 表明切换过渡需要较大峰值电流,建议选用能提供数安至十数安峰值电流的驱动器,并根据开关速度在 2Ω ~ 10Ω 范围选择栅极电阻以平衡 EMI、开关损耗与应力。
  • 开关损耗管理:Crss(米勒电容)在快速切换时会产生米勒平台,需控制 dv/dt 并配合合适的死区时间和驱动阻尼,减少开关交叉导通损失。
  • 热管理:TO252-3L 封装在高电流工作时需靠 PCB 铜箔扩散与热垫,建议在底层放置大量热过孔并连接大面积散热铜区,评估实际结温并保证在额定 Pd 与工作温度范围内运行。

五、布局与可靠性注意事项

  • 布线:功率回路尽量缩短,减小感抗与寄生电阻,布局时将驱动回路与功率回路分离以降低干扰。
  • 退耦与滤波:在 MOSFET 与电源之间靠近放置低 ESR 输入电容,减少电压尖峰和应力。
  • 保护:在高应力或未知负载条件下建议搭配过流、过温及软启动电路,必要时并联阻尼或 TVS 保护以防尖峰越压。
  • 可靠性:器件通过完整功能可靠性认证并保证 EAS,长期可靠性需结合系统热循环与应力验证。

六、封装与采购提示

TO252-3L 紧凑封装利于表面贴装与自动化贴装,但需注意热沉设计。购买或设计时请核对批号与相关可靠性文件,依据应用场景选择合适的栅极驱动与 PCB 散热方案。

总结:XR100N03 在 30V/100A 档位提供了低 RDS(on) 与合理的开关特性,适合高密度同步降压与大电流功率级。合理的驱动与散热设计将最大化其效率与可靠性。若需具体热阻、SOA 或封装机械图纸,可向供应商索取数据手册与样片测试报告。

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
