XR50N04 产品概述

一、产品简介

XR50N04 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道功率 MOSFET,采用 TO252-3L(俗称 DPAK)封装。器件设计面向同步降压转换器及高效率开关电源应用,兼顾低导通损耗与合理的开关特性,满足 RoHS 与绿色环保要求,同时 100% 保证雪崩能量耐量(EAS),适用于有能量吸收或硬开关工况的系统。

二、主要参数

  • 类型:N 沟道 MOSFET(单只)
  • 漏源电压 Vdss:40 V
  • 连续漏极电流 Id:50 A
  • 导通电阻 RDS(on):12 mΩ @ Vgs = 10 V
  • 阈值电压 Vgs(th):2 V
  • 总栅极电荷 Qg:22.9 nC @ 10 V
  • 输入电容 Ciss:964 pF;输出电容 Coss:109 pF;反向传输电容 Crss:96 pF
  • 功耗 Pd:20 W(封装额定)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L(DPAK)
  • 认证/特性:RoHS、绿色产品、100% EAS

三、关键特性与优势

  • 低 RDS(on):12 mΩ(10 V 驱动)在导通损耗上具有明显优势,适合低压大电流场合,能有效降低导通损耗与发热。
  • 平衡的栅极电荷与电容特性:Qg=22.9 nC、Coss/Crss 中等,兼顾导通与开关损耗,利于在高效率与高速切换之间取得平衡。
  • 高雪崩能量可靠性:100% EAS 保证,适合有感性负载或瞬态冲击的应用,提高系统鲁棒性。
  • TO252 封装:适用于表面贴装,便于自动化生产,且在 PCB 散热设计合理时能提供较好的热性能。

四、典型应用

  • 同步降压转换器(低侧或高侧,建议 10 V 驱动以获得标称 RDS(on))
  • 开关电源与点对点稳压模块(VRM)
  • 电源管理与电机驱动的低压大电流开关器件
  • 感性负载或需能量吸收的功率开关场合

五、设计与使用注意事项

  • 驱动电压:为达到标称 RDS(on),建议采用 10 V 的门极驱动电压;Vgs(th)≈2 V,低压逻辑直驱不能保证最低 RDS(on)。
  • 栅极驱动能力:Qg 较大,快速切换时需足够的驱动电流与合适的栅阻以控制 dv/dt 和振铃,避免过高的开关损耗与电磁干扰。
  • PCB 布局与散热:TO252 依赖 PCB 的铜区域散热,建议增大封装底部及引脚附近的铜箔面积、采用多通孔过孔导热至底层铜,并保持短粗的电源回路以降低寄生电阻/电感。
  • 抗浪涌与保护:尽管器件具备 EAS 保证,但在实际应用中应配合合适的缓冲、吸收或限流措施(如 TVS、软启动、电流检测)以延长寿命并提升系统安全性。
  • 开关布局:关注 Crss 与 Coss 对死区时间和占空比转换的影响,在同步整流控制上合理设置死区时间以防止交叉导通损耗。

六、可靠性与封装信息

XR50N04 满足 RoHS 绿色环保标准,并通过完整的功能可靠性认证;100% 雪崩能量测试提升了器件在冲击和感性负载下的可靠性。TO252-3L 封装便于表面贴装生产,通过良好 PCB 散热设计可发挥 20 W 的封装功耗能力。

总结:XR50N04 以 40 V 电压等级、12 mΩ 的低 RDS(on) 与中等栅极电荷为设计目标,适合对效率与成本均有要求的同步降压与开关电源应用。在系统设计时,合理的栅极驱动与散热布局是发挥该器件性能的关键。若需更详细的绝对最大额定值、温度特性曲线或封装图纸,建议参考厂家完整数据手册或直接联系 XNRUSEMI(新锐)技术支持。

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
