XR120N02 产品概述

一、概述

XR120N02 是 XNRUSEMI(新锐)推出的一款高密度沟槽式 N 沟道 MOSFET,专为同步降压转换器及高电流开关电源系统设计。器件在低电压下提供极低导通电阻和良好的开关性能,适合高效电源级和功率密集型应用。符合 RoHS 与绿色产品要求,100% 保证雪崩能量耐量,并通过完整功能可靠性认证,可靠性指标可靠,能够满足工业级应用需求。

关键标称参数(典型/测试条件):

  • 类型:N 沟道沟槽式 MOSFET
  • 漏源电压 Vdss:20 V
  • 连续漏极电流 Id:120 A
  • 导通电阻 RDS(on):3.27 mΩ @ Vgs = 2.5 V
  • 阈值电压 Vgs(th):1.0 V
  • 总栅极电荷 Qg:70 nC @ Vgs = 4.5 V
  • 输入电容 Ciss:5.67 nF
  • 反向传输电容 Crss:416 pF
  • 功耗 Pd:69 W
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO-252-3L (DPAK)
  • 品牌:XNRUSEMI(新锐)

二、主要特性与优势

  • 极低导通电阻:3.27 mΩ(Vgs = 2.5 V),在低电压门极驱动条件下即可获得优异导通性能,有利于降低导通损耗,提高转换效率。
  • 合理的栅极电荷:Qg = 70 nC(4.5 V),在追求低导通损耗与可控开关速度之间取得平衡,适合主流门极驱动器。
  • 小电容矩阵:Ciss 与 Crss 值使开关损耗可预测,便于进行开关优化与 EMI 管理。
  • 强化可靠性:100% 雪崩能量耐量保证,并通过完整功能可靠性认证,适合需要长寿命与高可靠性的应用场景。
  • 工业温度等级:-55 ℃ 到 +150 ℃ 的宽温工作范围,适用于严苛环境。

三、典型应用场景

  • 同步降压(synchronous buck)转换器的高端/低端 MOSFET(尤其适合低电压、高电流点)
  • 服务器与通信电源的输出级与输入级电源管理
  • 电池供电系统与便携式电源的主开关器件
  • 电机驱动、DC-DC 模块、充电器与功率分配单元
  • 对可靠性要求高的工业与汽车电子(非典型车规认证需另议)

四、设计与布局建议

  • 门极驱动:鉴于器件在 Vgs = 2.5 V 下已提供极低 RDS(on),可采用低电压门极驱动策略以减少门极电压应力。但注意 Qg = 70 nC 在快速开关时会产生较大的瞬时驱动电流,门极驱动器需具备相应电流能力或通过串联门阻(Rg)控制开关速度以降低 EMI 与振铃。
  • Miller 效应与 Crss:Crss = 416 pF 表明在高 dV/dt 条件下存在明显的 Miller 偏置效应,建议在设计时考虑适当的 Miller 抑制(如降低驱动速度或增加阻尼),并在高侧/低侧切换节点使用合适的缓冲与钳位电路。
  • PCB 布局:为发挥低 RDS(on) 优势,应保证电流路径的铜箔尽可能宽且短,使用多层大功率平面、充足的过孔和底层散热铜柱来降低寄生电阻与热阻。有条件时在 DPAK 焊盘下加入散热焊盘并通过热过孔连接至内层/底层散热铜。
  • 并联与热均衡:当单片器件电流不足以满足系统需求时,可并联多片使用,但需注意器件间的电流均衡与门极驱动同步,必要时加入小电阻进行电流均衡与止振。
  • 热管理:器件标称Pd = 69 W(器件耗散能力与实际热阻、环境条件相关),在实际应用中应结合封装与 PCB 热阻评估结温并采取必要散热措施以保证长期可靠工作。

五、封装与焊接要点

  • TO-252-3L(DPAK)封装适用于表面贴装自动化装配,便于在电源模块与主板中实现高密度布局。
  • 焊接推荐遵循标准回流曲线,并在焊盘设计中保留足够的散热焊盘与热过孔,以确保散热路径良好。
  • 储存与处理遵守静电防护(ESD)规范,避免门极与泄漏引脚受损。

六、可靠性与合规

  • 器件通过完整功能可靠性认证并且 100% 保证雪崩能量耐量,增强在突发能量事件下的系统容错能力。
  • 满足 RoHS 与绿色产品要求,便于在环保合规项目中应用。

总结: XR120N02 将低导通电阻与可控开关性能结合在紧凑的 DPAK 封装中,适合要求高效率、高电流且对可靠性有较高要求的电源设计。合理的门极驱动、严谨的 PCB 布局与充分的散热设计,能够使该器件在同步降压转换器、服务器电源、工业电源等场景中发挥最佳性能。若需更详细的电气特性曲线、脉冲限制、热阻及典型应用电路建议,可提供器件规格书以供进一步设计校核。

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.
