XRT90N20T(XNRUSEMI 新锐)产品概述

一、产品简介

XRT90N20T 是一款 200V 耐压、N 沟道功率 MOSFET,采用 TO-220AB 封装,面向开关电源、逆变器、电机驱动和高压开关应用。主要参数:Vdss=200V、Id=90A(连续)、RDS(on)=25mΩ @ Vgs=10V、Qg=130nC @10V、Ciss=5.871nF、Crss=165pF、Coss=392pF、Vgs(th)=4V,器件额定耗散功率 Pd=375W(按器件规格条件)。品牌:XNRUSEMI(新锐)。

二、关键电气特性与设计要点

  • 导通性能:典型 RDS(on)=25mΩ(Vgs=10V),在大电流导通时导通损耗显著(Pcond = I^2·RDS(on))。例如:30A 时约 22.5W,60A 时约 90W,选择散热和热阻时必须充分考虑。
  • 门极驱动:Qg=130nC(10V),需较大瞬间驱动电流以实现快速开关。若驱动器峰值电流为 2A,则理论上充放电时间约 65ns;若为 1A 则约 130ns。门极驱动损耗 Pgate = Qg·Vdrive·f,例如 f=100kHz、Vdrive=10V 时 Pgate ≈ 0.13W。
  • 开关损耗:Coss=392pF,可近似估算每次开关的 Coss 损耗 0.5·Coss·V^2(V=关态电压)。以 V=200V 为例,每次切换能量约 7.84µJ,若开关频率 100kHz,对应约 0.78W(单次边沿)。因此在高频应用下开关损耗与门极损耗不可忽视。
  • 驱动电平与阈值:Vgs(th)=4V,建议采用 10V 门极驱动以达到标注的低 RDS(on)。5V 或更低门极驱动无法保证低导通电阻,影响效率。

三、封装与热管理

TO-220AB 封装便于散热片安装与穿孔安装,散热片或强制风冷几乎是高电流工作必需。背板(散热片/引线框)通常与漏极(Drain)相连,安装时注意绝缘或接地需求,使用合适的导热垫和均匀螺栓压紧以减少热阻。具体螺丝扭矩和散热条件请参考详细数据手册和系统热设计。

四、PCB 布局与保护建议

  • 布局:缩短信号和功率回路环路面积,Gate 与 Source 之间走短回路以减小感性耦合;驱动端使用 Kelvin 源引脚(若可用)或尽量将驱动参考点靠近器件。
  • 限制振铃:建议在门极串联 5–22Ω(根据布局与所需开关速度调整)以抑制振铃并控制 dV/dt。
  • 保护:添加 TVS、RC 缓冲或吸收网络限制峰值电压,使用合适的栅极钳位(避免超 Vgs),在高能量场合考虑软关断或能量吸收器件以避免器件进入大能量雪崩状态。
  • 焊接与可靠性:TO-220 引脚适合波峰或手工焊接,注意热循环与机械应力管理。

五、典型应用场景

  • 高压开关电源(LLC、反激、正激)
  • 功率因数校正(PFC)开关管
  • 电机驱动与工业逆变
  • 同步整流/降压/升压变换器

总结:XRT90N20T 以 200V/90A 的规格配合较低的 RDS(on)(在 10V 门极下)适合中高功率、高频率的电源与驱动场合。设计时需关注门极驱动能力与吸收/限压措施,以及充足的散热设计来保证器件在高电流条件下的可靠工作。若用于具体产品,请参照完整数据手册以获取最大额定值、热阻、浪涌性能和绝对极限参数。

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.
