XR30N02(XNRUSEMI 新锐)产品概述

一 产品概述与主要参数

XR30N02 是一款高单元密度的沟槽N沟道功率MOSFET,面向同步降压等开关电源开关应用。主要参数如下:

  • 数量:1个N沟道
  • 漏源电压 Vdss:20 V
  • 连续漏极电流 Id:30 A
  • 导通电阻 RDS(on):12 mΩ @ Vgs = 4.5 V
  • 最大耗散功率 Pd:5 W
  • 阈值电压 Vgs(th):0.7 V(700 mV)
  • 总栅极电荷 Qg:10.5 nC @ 10 V
  • 输入电容 Ciss:700 pF;反向传输电容 Crss:105 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L(DPAK)
  • 符合 RoHS,100%保证雪崩耐量,具备完整功能可靠性认证

二 特性与优势

  • 低导通电阻(12 mΩ @ 4.5 V)在中低电压(如12 V母线、5 V/3.3 V降压调节)场景下可显著降低导通损耗,提升效率。
  • 较高的连续电流能力(30 A)适用于高电流点负载与多路输出场合,但需配合良好散热。
  • Qg=10.5 nC(@10 V)和Ciss/Crss值表明在保持较低导通损耗的同时,驱动电荷适中,有利于实现快速开关且驱动功耗可控。
  • TO252-3L 封装适合表面贴装,便于模块化设计和中等功率散热方案。
  • 100%雪崩耐量和完整可靠性认证,适合高可靠性要求的产品设计。

三 典型应用

  • 同步降压转换器(主/同步开关)
  • 点-of-load(POL)稳压模块与服务器电源
  • 电池管理与便携电源开关
  • 通信电源、工业电源和车载辅助电源(符合电压等级要求时)

四 设计与驱动建议

  • 驱动:推荐使用 4.5 V~10 V 的栅极驱动电压以在效率与开关应力之间取得平衡;若采用 10 V 驱动,驱动损耗 Pgate = Qg × Vdrive × fs(例如 fs=500 kHz 时,Pgate ≈ 10.5e‑9×10×5e5 ≈ 0.0525 W)。
  • 栅极电阻:5~20 Ω 常用于抑制振铃与限流,具体值依据PCB寄生电感和驱动器能力调整。
  • Miller 效应:Crss = 105 pF,注意在快速开关时 Miller 电容引起的电压翻转与开关损耗,必要时增加栅极阻尼或采用驱动器有源回灌控制。

五 热管理与可靠性提醒

  • 虽然标称 Id 可达 30 A,但器件的实际连续电流能力受散热条件限制。按 RDS(on) 12 mΩ 计算:I = 30 A 时导通压降 ~0.36 V,对应导通损耗 P = I^2×R ≈ 10.8 W,远超 Pd = 5 W,因此高电流场合必须通过散热片、铜箔加厚、底部大焊盘和多盏过孔来散热并降低结温。
  • 建议在热仿真与实际样机验证中确认结温(Tj)不超过额定范围,以保证长期可靠性。
  • 本器件100%保证雪崩耐量,有利于应对瞬态过压,但不能替代良好的过压保护与电路设计。

六 封装与合规

  • TO252-3L(DPAK)表面贴装封装,适合自动贴装与回流焊工艺。建议在PCB设计时预留足够的散热铜箔和多孔过渡,以提高热传导效率。
  • 满足 RoHS 与绿色产品要求,适用于环保合规项目。

七 选型与设计提示

  • 若系统工作在高占空比、高电流场景,应优先做热设计与Junction温度评估,必要时选择更大Pd或外加散热方案。
  • 选型时结合开关频率、驱动电压与系统效率目标:低 RDS(on) 有利于降低导通损耗,适中 Qg 有利于降低驱动功耗与控制EMI。
  • 在并联或多相设计中注意匹配RDS(on)与导通均衡策略,确保热均匀性。

XR30N02 面向高效同步降压与中高电流点负载场景,在保证可靠性的前提下提供较低导通损耗与合理的开关性能,是空间受限且需表面贴装的中功率设计的优选。请在最终应用中结合实际散热条件与试验数据进行确认。

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
