XR40N04 产品概述

一、产品简介

XR40N04 是 XNRUSEMI(新锐) 推出的高细胞密度沟槽式 N 沟道 MOSFET,额定漏源电压 40V,适用于多数小功率开关与负载开关场合。器件在 TO252-3L(DPAK)表面贴装封装下提供低导通电阻与较小的栅极电荷,兼顾导通损耗与开关损耗,满足 RoHS 与绿色产品要求,并具备完整功能可靠性认证。

二、主要电气参数

  • 类型:N 沟道 MOSFET(沟槽式、高细胞密度)
  • Vdss:40 V
  • 连续漏极电流 Id:40 A(在充分散热条件下)
  • 导通电阻 RDS(on):18 mΩ @ Vgs = 10 V
  • 最大耗散功率 Pd:12.5 W(封装条件下)
  • 阈值电压 Vgs(th):2 V(典型)
  • 总栅极电荷 Qg:12 nC @ 10 V
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L(DPAK)

三、性能要点与工程参考

  • 低导通电阻:在 Vgs=10V 时 RDS(on)=18 mΩ,适合高电流低压降的开关场合。
  • 栅极驱动:Qg=12 nC,Vgs=10V 时栅极充电能量 E_gate ≈ 0.5·Qg·Vgs = 60 nJ,若开关频率为100 kHz,则栅极驱动功耗约为6 mW,栅极驱动损耗较小,但应同时关注过渡态的能量损失。
  • 热限与连续电流:器件标称连续 Id=40A,实际连续电流受散热条件限制。基于 Pd=12.5W 与 RDS(on)=18 mΩ,可估算在无额外散热条件下安全连续电流约为 sqrt(Pd/R) ≈ 26 A;若需长期 40 A 工作,必须采用良好散热(大铜箔、散热片或外部冷却)。
  • 阈值与驱动电平:Vgs(th)≈2V,但 RDS(on) 在 10V 时保证,5V 逻辑电平下导通电阻可能显著增加,非严格保证的“逻辑级”器件,驱动建议采用 10V 档位以达到最低 RDS(on)。

四、封装与散热建议

TO252-3L(DPAK)适合表面贴装,便于自动化生产。为优化散热与稳定性建议:

  • 在 PCB 底层留较大铜面作为散热区,并采用多孔过孔(thermal vias)将热量导至内层或底层铜箔。
  • 将源脚与散热铜箔良好焊接,必要时在器件下方/周围增加焊盘面积。
  • 如需高连续电流,考虑加装散热片或使用强制风冷。

五、驱动与电路设计建议

  • 推荐 Vgs=10V 驱动以获得标称 RDS(on)。
  • 串联门极电阻(例如 5–22 Ω)以抑制振铃并控制开关速度,避免过高 dV/dt 导致 EMI 或寄生振荡。
  • 在开关瞬态中使用栅极 TVS 或RC阻尼网络保护栅极免受过压和环路噪声影响。
  • 对于感性负载,注意体二极管的整流与吸收能量,必要时并联快恢复二极管或使用吸收电路以保护 MOSFET。
  • 布局上保持电源回路短且宽,靠近器件放置去耦电容以降低开关损耗与电压尖峰。

六、可靠性与合规

型号符合 RoHS 与绿色产品标准,并通过完整功能可靠性认证,适合在工业及消费类电子中长期部署。工作温度范围宽(-55 ℃ 到 +150 ℃),适应高温环境,但应避免长期在最大结温附近运行。

七、典型应用

  • DC-DC 降压及同步整流(小功率)
  • 负载开关、电源管理与分配
  • 汽车电子(24V/12V 边界应用)与电机驱动前端(配合合适散热及保护)
  • 开关电源、充电器与逆变器辅助开关

八、选型注意事项

  • RDS(on) 数据以 Vgs=10V 为准,若系统仅有 5V 驱动,应验证导通损耗与效率是否可接受。
  • 评估连续电流时以热阻与散热方案为主,避免仅依据 Id 标称值。
  • 并联使用时注意共享电流不均问题,建议加入小阻值源阻(均流)或匹配器件并改进散热。
  • 使用前请参阅完整数据手册获取热阻、极限参数和开关能量曲线(SOA/Avalanche 数据)以完成安全设计。

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.
