XR90N04 产品概述

一、主要特性

XR90N04 是一款高单元密度沟槽式 N 沟道 MOSFET,针对同步降压转换器及各类功率开关场合进行了优化设计。主要参数如下:

  • 数量:1个 N 沟道
  • 漏源耐压 Vdss:40 V
  • 连续漏极电流 Id:90 A
  • 导通电阻 RDS(on):4.5 mΩ @ Vgs = 10 V
  • 功耗耗散 Pd:60 W
  • 阈值电压 Vgs(th):1.8 V
  • 栅极电荷量 Qg:59 nC @ 20 V
  • 输入电容 Ciss:3.031 nF
  • 反向传输电容 Crss:179 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L(DPAK)
  • 品牌:XNRUSEMI(新锐)
  • 其它:符合 RoHS 及绿色产品要求,100% 保证雪崩能量(EAS),具备完整功能可靠性认证

二、应用场景

XR90N04 适合要求低导通损耗与中高速开关的功率电子应用,典型包括:

  • 同步降压转换器(服务器、电源模块、消费类电源)
  • DC–DC 电源开关管
  • 电机驱动与负载开关
  • 高效电源管理与功率整流场合

三、性能与驱动建议

  • 为实现标称 RDS(on)(4.5 mΩ),建议在 Vgs ≈ 10 V 下驱动;若使用较低驱动电压,导通电阻将上升,需在设计时考虑。
  • 栅极电荷 Qg = 59 nC(20 V)表明该器件栅极电容较大,驱动器需具备充放电能力以满足预期开关频率,避免因驱动能力不足而增加开关损耗或延迟。
  • Ciss = 3.031 nF 和 Crss = 179 pF 提示在高速切换时需关注 Miller 效应与电磁兼容(EMI),可能需要合适的门极电阻或缓冲电路以抑制振铃。

四、封装与散热建议

  • TO252-3L(DPAK)封装适合表面贴装,便于批量生产和散热处理。请确保焊盘和底层大面积铜箔(thermal pad)以降低结到环境的热阻。
  • 60 W 的耗散能力需要配合 PCB 散热设计:加宽电源走线、增加过孔连接多层散热铜箔、并尽量缩短高电流回路长度以减少寄生电感。
  • 在高频或高电流应用中,注意器件结温控制,建议在工作点上进行热仿真与实测验证。

五、可靠性与合规

  • 该器件符合 RoHS 与绿色产品要求,适用于对环保合规有要求的产品设计。
  • 厂方承诺 100% 雪崩能量(EAS)保证,增强在瞬态过压或开关异常情况下的可靠性。但在实际应用中仍应通过合理的保护电路(TVS、软启动、过流保护等)来防止极限工况。

六、选型与实用注意事项

  • 如果系统工作电压接近 40 V 或存在较大浪涌,应评估安全裕度;在高侧或半桥应用中需兼顾栅极驱动电压与绝缘设计。
  • 对于高开关频率设计,需平衡导通损耗与开关损耗:XR90N04 的低 RDS(on) 有利于降低导通损耗,但较高的 Qg 会增加驱动损耗与开关损耗。
  • 布局建议:尽量缩短 MOSFET 的源极至驱动器回流路径,分离功率与信号地,使用适当的去耦电容靠近器件以抑制电压尖峰。

七、总结

XR90N04(XNRUSEMI)以 40 V 耐压、低至 4.5 mΩ 的导通电阻和较大的电流承载能力,为同步降压转换器和各类功率开关应用提供了良好的性能基础。在选型与应用时,应重视栅极驱动能力、热管理和 PCB 布局,以发挥器件最佳的效率和可靠性。若需进一步的电气特性曲线或封装尺寸图,请参考厂方详细数据手册或联系供应商获取支持。

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
