XR40N02 产品概述

一、概述

XR40N02 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道 MOSFET,额定漏源电压 Vdss = 20V,连续漏极电流 Id = 40A,导通电阻 RDS(on) = 8mΩ(Vgs = 4.5V)。器件符合 RoHS 与绿色产品要求,100% 保证雪崩耐量,适合多数同步降压转换器与高频开关应用。

二、核心电气参数

  • Vdss:20V
  • Id(连续):40A
  • RDS(on):8mΩ @ Vgs = 4.5V
  • Vgs(th):0.75V(典型阈值)
  • Qg(总栅电荷):15nC @ 10V
  • Ciss(输入电容):1nF
  • Crss(反向传输电容):164pF
  • Pd:25W(耗散功率)
  • 工作温度:-55℃ ~ +150℃
  • 封装:TO252-3L

三、主要特性与优势

  • 低导通阻抗:在典型 4.5V 驱动电压下 RDS(on) 低至 8mΩ,适合低压大电流输出的同步整流或主开关应用。
  • 适中栅电荷:Qg = 15nC 在 10V 驱动下兼顾导通损耗与开关损耗,便于使用中等驱动能力的驱动芯片。
  • 高可靠性:100% 雪崩耐量测试,适合经常承受开关应力的系统。广泛温度范围保证工业级稳定性。
  • 体积与散热:TO252-3L(DPAK 类似)封装兼顾散热与 PCB 安装便利性,适合自动化回流焊装配。

四、典型应用场景

  • 同步降压转换器(同步整流器与低侧开关)
  • 高效率直流功率模块与电源管理(VRM/PMIC 辅助)
  • 电机驱动小功率级、锂电池保护(BMS)中低压段
  • 通用开关与负载开关场合

五、设计与使用建议

  • 栅极驱动:推荐驱动电压 4.5V ~ 10V,可在 4.5V 下实现规定 RDS(on)。驱动器平均电流约等于 Qg × f(例如 f = 500kHz 时 Iavg ≈ 15nC × 500kHz = 7.5mA),实际开关损耗受开关边沿时间影响,建议使用合适的驱动电阻控制 dv/dt 与 EMI。
  • 散热与布局:尽量缩短高电流回路(电感—MOSFET—电容)长度,使用大面积铜箔和过孔导热到多层内层或散热层,确保结温低于 150℃。TO252 的底部焊盘与引脚应良好焊接以提高散热能力。
  • 保护与可靠性:尽管器件 100% 雪崩耐量,但系统仍应考虑软栅与电流限制以防止长期应力。加入合理的 TVS 或吸收网络以抑制瞬态过压。
  • 测试与验证:在目标工作频率和电流下进行热仿真与实际温升测试,验证在最大工作点 Pd 与 PCB 散热条件下的结温与寿命。

六、合规与品质保证

XR40N02 满足 RoHS 与绿色产品要求,并经过完整的功能可靠性认证。厂方提供 100% 雪崩耐量检测,适用于对可靠性有较高要求的工业与消费类电源产品。

总结:XR40N02 在 20V/40A 等级中以低 RDS(on)、适中栅电荷和良好雪崩能力,提供了在同步降压与高频开关领域的性价比选择。合理的栅驱、良好的 PCB 散热与过压保护是发挥其性能与可靠性的关键。

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
