XR190N04G 产品概述

一、产品简介

XR190N04G 是 XNRUSEMI(新锐)推出的一款高性能 N 沟道功率 MOSFET,额定漏源电压 40V,面向高密度同步降压转换器和高电流开关应用。器件在 TO-263 封装下实现极低的导通电阻和良好的开关特性,适合要求高效率与高热耗散能力的电源前端与功率级设计。符合 RoHS 与绿色环保要求,100% 经雪崩耐量测试,保证功能与可靠性。

二、主要电气参数

  • 漏源电压 Vdss:40V
  • 连续漏极电流 Id(Tc):190A(受散热条件限制,实际可用电流以热设计为准)
  • 导通电阻 RDS(on):2.7mΩ @ Vgs=10V
  • 总栅极电荷 Qg:80nC @ Vgs=20V(典型测量条件)
  • 输入电容 Ciss:4.9nF
  • 反向传输电容 Crss:317pF
  • 最大耗散功率 Pd:61W(在规定散热条件下)
  • 工作温度范围:-55℃ ~ +150℃

三、特性亮点

  • 低导通电阻:2.7mΩ(10V 门压)在高电流应用中可显著降低导通损耗,提高转换效率。
  • 高单元密度:芯片结构与封装优化,支持高电流密度输出,适合小体积高性能电源模块。
  • 良好开关性能:适中的 Qg 与 Ciss/Crss 平衡了驱动能耗与开关过渡特性,有利于系统整体效率与 EMI 控制。
  • 完整的可靠性保证:满足 100% 雪崩耐量测试与功能可靠性验证,适用于要求长寿命与高可靠性的电源设计。

四、典型应用场景

  • 同步降压(buck)转换器的高侧或低侧开关
  • 服务器与通信设备的点对点供电模块
  • DC-DC 电源模块与电池管理系统(BMS)
  • 高频电源、功率级开关、主开关与同步整流器

五、使用要点与布局建议

  • 门极驱动:RDS(on) 数据以 Vgs=10V 为准,推荐采用 10~12V 门极驱动以获得最低导通损耗;Q g 较大时需选择驱动器或驱动电流足够的驱动电路,避免开关缓慢导致的高损耗。
  • 开关速度与栅极电阻:根据系统对 EMI 与损耗的权衡,使用合适的门极电阻(通常几欧姆到几十欧姆)以控制振铃和压摆率。
  • 散热设计:TO-263 封装配合大面积 PCB 铜箔和热过孔可有效提升散热能力。Pd=61W 为参考值,实际最大允许电流应依据结-散热温升与 PCB 设计重新评估。
  • 保护与钳位:尽管器件经过雪崩测试,仍建议在高应力场合采取过压、过流保护及合适的续流路径,使用缓冲网络或 RC 吸收来抑制开关瞬态。

六、合规与可靠性

  • 符合 RoHS 与绿色环保要求,适合各类环保制品认定与出口应用。
  • 100% 雪崩耐量测试并通过完整功能可靠性验证,适用于需要高可靠性的电源与功率电子产品。

总结:XR190N04G 以其低 RDS(on)、高电流能力与平衡的开关特性,适合用于高效率同步整流与功率转换场景。设计时应关注门极驱动能力与 PCB 散热布局,以发挥器件的最佳性能。如需详细的典型应用电路、温升曲线或 SOA 数据,建议参考器件完整数据手册或联系供应商获得支持。

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
