XR10N10S 产品概述

一 产品简介

XR10N10S 是 XNRUSEMI(新锐)推出的一款高性能沟槽 N 沟道 MOSFET,额定漏源电压 Vdss = 100V,连续漏极电流 Id = 10A,导通电阻 RDS(on) = 115mΩ(VGS=10V),阈值电压 Vgs(th)=2.5V。该器件具有高单元密度、低栅极电荷与合理的寄生电容(Ciss=610pF、Coss=40pF、Crss=25pF),适合多数同步降压转换器与开关电源应用。符合 RoHS 与绿色产品要求,并通过全面可靠性认证,100% 保证雪崩能量耐量。

二 关键参数解读与设计影响

  • 导通性能:RDS(on)=115mΩ(VGS=10V)说明在 10V 驱动下导通损耗较低,但在 5V 驱动下 RDS(on) 会明显上升,建议使用 ≥10V 的门极驱动以获得额定导通特性。
  • 开关性能:Qg=12nC(@10V)与 Ciss=610pF 表明对驱动器要求适中。举例:在 500kHz 工作频率下,门极驱动功耗约为 Pgate = Qg×Vgs×f = 12nC×10V×500kHz ≈ 0.06W(60mW),门极电流平均值约为 6mA,实际脉冲电流较大,应选用能提供峰值电流的驱动器。
  • 输出电容与开关损耗:Coss=40pF,对 100V 全摆幅切换时,每次换向消耗能量约 E = 0.5·Coss·V^2 ≈ 0.2μJ;在 100kHz 切换时相当于约 0.02W 的开关损耗(实际系统中受电流、死区与回路影响)。
  • 热限与功耗:封装耗散功率 Pd=5W,应与封装热阻和PCB散热方案配合使用。若在 10A 连续导通下按 RDS(on) 计算,Pcond = I^2·R ≈ 11.5W,明显超过封装 Pd,需外部散热或限制脉冲占空比。

三 典型应用场景

  • 同步降压转换器(主开关或同步整流)
  • 高效 DC-DC 转换模块
  • 电源管理与负载开关
  • 中小功率电机驱动与功率分配

四 热设计与可靠性建议

  • SOP8 小封装热阻较大,瞬态脉冲可允许较高电流,但长期连续 10A 需借助大铜面积散热、底层散热平面与多个过孔通到内层/底层散热层。
  • 设计时应计算总损耗(导通损耗 + 开关损耗 + 驱动损耗),并确保器件结温低于最大工作温度(-55℃~+150℃)的安全范围。
  • 产品已保证雪崩能量耐量,但在系统设计中仍建议避免频繁大幅度漏源电压尖峰,采取 RC、TVS 或合理的回路阻尼抑制振铃。

五 PCB 布局与驱动建议

  • 最小化高电流回路环路面积(电感与寄生电阻直接影响开关应力与 EMI)。
  • 在 MOSFET 的源极与驱动地之间采用短、粗的回路,并采用“凯尔文”式门极连接(将驱动信号与功率源分开)。
  • 推荐门极串联电阻 5Ω–15Ω(根据系统振铃与驱动能力调整),在高频切换时适当增加阻值可抑制振铃与降低瞬态应力。
  • 对于并联使用,应确保良好电流分享与一致的驱动网络。

六 包装与合规

  • 封装:SOP8,适合表面贴装自动化生产。需注意 SOP8 的散热局限,通过 PCB 热铜和过孔增强散热。
  • 环保与可靠性:符合 RoHS,经过全功能可靠性认证,适用于对可靠性有较高要求的工业与消费电子领域。

总结:XR10N10S 在 100V 等级中提供了平衡的导通电阻与开关特性,适合多数同步降压与中小功率开关应用。要达到标称电流能力,需在驱动与散热上做良好设计,避免长期在器件封装极限附近工作。若需并联或更高连续功率,建议评估更大封装或外置散热措施。

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
