XR3350M 产品概述

XR3350M 是 XNRUSEMI(新锐)推出的一款双通道 N 沟道 TrenchFET 功率 MOSFET,集成于 DFN3030-8L 表面贴装封装,专为高功率密度、低开关损耗和高电流处理场合设计。器件采用先进高单元密度沟槽工艺,兼顾极低导通电阻与超低栅极电荷,适合同步整流、DC-DC 转换、电机驱动及负载开关等应用。

一、主要电气性能亮点

  • 漏源电压 Vdss:20 V,适用于低压高电流系统。
  • 连续漏极电流 Id:50 A(单通道),满足高电流要求。
  • 导通电阻 RDS(on):3.2 mΩ @ Vgs=4.5 V,逻辑电平驱动即可实现极低导通损耗。
  • 阈值电压 Vgs(th):0.6 V,便于在低驱动电压下快速导通。
  • 总栅极电荷 Qg:36 nC @ 10 V,栅极驱动能量需求低,有利于降低开关能耗。
  • 输入电容 Ciss:2.61 nF,反向传输电容 Crss:322 pF,器件切换特性良好。
  • 工作温度范围:-55 ℃ 至 +150 ℃,耐热能力强。
  • ESD 防护:HBM 2000 V。

二、关键特性与设计优势

  • 先进 TrenchFET 结构与高单元密度工艺,使得在 20 V 级别下也能提供极低的 RDS(on) 与高电流承载能力。
  • 超低栅极电荷与较小 Ciss 有利于降低栅极驱动损耗,提升开关效率,尤其适合高频开关场合。
  • 优秀的 CdV/dt 抑制能力可减小器件间寄生耦合导致的误导通,提升同步整流和半桥拓扑的可靠性。
  • DFN3030-8L 表面贴装封装适合自动化贴装与窄板设计,有利于提高功率密度和制造一致性。
  • 环保无铅制造,符合现代电子产品合规要求。

三、典型应用场景

  • 同步降压(synchronous buck)转换器:作为高侧/低侧功率开关,可降低导通与开关损耗。
  • 高电流负载开关与电源管理:服务器、通信、电源模块中的负载切换与保护。
  • 电机驱动与电源逆变器:中小功率电机控制及驱动级。
  • 电池保护与电源路径管理:便携设备与储能系统中的高效开关元件。

四、封装与布局建议

  • DFN3030-8L 有利于热传导,但建议在 PCB 热层处采用大面积敷铜和多盏过孔(vias)将热量导入内层或散热层,以降低结至环境热阻。
  • 尽量缩短栅极、漏极与源极的走线,减小寄生电感,提升开关性能并降低振铃。
  • 栅极驱动路径应匹配合适驱动能力;由于 Qg=36 nC(@10 V),在高频应用中需选用驱动电流足够的驱动器以获得快速、受控的开关边沿。
  • 对于敏感电路,利用良好的地平面和旁路电容来抑制开关干扰,配合布局上的 CdV/dt 抑制特性可进一步提升系统稳定性。

五、使用注意事项

  • 虽然 Vgs(th) 低、在 4.5 V 已能实现低 RDS(on),但器件的最大 Vgs 和瞬态应遵循厂方极限(如未提供请参照样片或规格书确认),避免过压导致栅氧损伤。
  • 在高频或高电流切换场合需权衡导通损耗与开关损耗,合理选择驱动电压与死区时间。
  • 推荐在开发阶段进行热仿真与实测评估,确保在实际工作点下结温保持在器件额定范围内。

XR3350M 以其低 RDS(on)、超低栅极电荷、优良的 CdV/dt 抑制和 DFN 小封装特性,为追求高效率与高功率密度的设计提供可靠元件选择。如需更详细的电气特性曲线、封装引脚分配或参考布局,请联系 XNRUSEMI(新锐)获取完整规格书与参考设计。

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
