XR90N03 产品概述

XR90N03 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽型 N 沟道功率 MOSFET,面向同步降压转换器及高电流开关应用,兼顾极低导通损耗与良好开关性能。器件采用 TO252-3L 封装,适合在有限空间内实现高效散热和大电流传输。

一、关键参数速览

  • 型号:XR90N03(XNRUSEMI / 新锐)
  • 极性:N 沟道(单个)
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:90 A
  • 导通电阻 RDS(on):3.2 mΩ @ Vgs = 10 V
  • 最大耗散功率 Pd:46 W
  • 栅极阈值电压 Vgs(th):1.6 V
  • 总栅极电荷量 Qg:20 nC @ 15 V
  • 输入电容 Ciss:2.088 nF
  • 反向传输电容 Crss:209 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L
  • 环保与可靠性:符合 RoHS 与绿色产品要求,100% 保证 EAS,具有完整功能可靠性认证

二、特性与优势

  • 极低导通电阻(3.2 mΩ @10 V):在中低压高电流场合可显著降低导通损耗,提高转换效率并减小热量产生。
  • 合理的栅极电荷(20 nC @15 V):在保持低导通电阻的同时控制开关能耗,便于与常见门驱动器匹配。
  • 宽温度范围与高耗散能力:-55 ℃ 至 +150 ℃ 的工作温度和 46 W 的耗散能力使器件在严苛环境和高功率密度设计中更可靠。
  • 小型封装(TO252-3L):兼顾散热与板上布局,适用于功率密度受限的应用。

三、典型应用场景

  • 同步降压(synchronous buck)稳压器与电源模块
  • 服务器与通信供电、点对点(point-of-load)转换器
  • 电池管理与电源分配系统
  • 电机驱动(中低压)与功率开关场合

四、设计要点与建议

  • 栅极驱动:器件在 Vgs = 10 V 条件下具有标定 RDS(on),建议门驱动电压采用 10–12 V 以获得最佳导通性能;注意 Qg=20 nC 在高频切换时对驱动器瞬态电流要求较高,应选用足够驱动能力的门极驱动芯片或驱动电路。
  • 开关损耗:虽然 RDS(on) 很低,但在高频开关时,Crss(209 pF)和 Qg 会带来显著切换损耗,需在系统级权衡开关频率与效率。
  • 热管理与 PCB 布局:为发挥 46 W 的散热能力,应在 PCB 上提供宽敷铜层或铜驻流区域,缩短信号回路与功率回路的环路面积,优化散热路径;必要时采用散热片或底部焊盘过孔导热到散热层。
  • 电磁兼容(EMC):减小器件周围寄生电感,放置旁路电容(低 ESR)靠近器件电源引脚,以抑制电压尖峰与振铃。

五、可靠性与合规

XR90N03 满足 RoHS 及绿色环保要求,产品通过完整的功能可靠性认证,并声明 100% 保证 EAS。器件在规格化测试条件下可提供稳定的电气特性,适合商业与工业级电源应用。

结论:XR90N03 在 30 V 级别的高电流开关应用中具有极具竞争力的导通电阻与可靠的热性能,是同步降压转换器和高密度电源设计的优选器件。在实际设计中,请结合系统开关频率、驱动能力及散热方案进行全面评估,并参考厂商完整数据手册以获取详细的极限参数与典型性能曲线。

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.

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
