XR60N04B 产品概述

一、概述

XR60N04B 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 = 40V,连续漏极电流 Id = 60A,主要面向同步降压转换器及高电流开关应用。器件符合 RoHS 与绿色环保要求,100% 保证雪崩耐量(EAS),并通过完整的功能可靠性认证,封装为 TO252-3L(俗称 DPAK),便于表面贴装与大电流 PCB 散热设计。

二、主要电气参数

  • Vdss:40 V
  • 连续泄漏电流 Id:60 A
  • 导通电阻 RDS(on):14 mΩ @ Vgs = 4.5 V
  • 门阈电压 Vgs(th):2.5 V
  • 总栅电荷 Qg:16 nC @ 4.5 V
  • 输入电容 Ciss:1.639 nF
  • 输出电容 Coss:148 pF
  • 反向传输电容 Crss:122 pF
  • 功耗 Pd:34.6 W(视封装与散热条件)
  • 工作温度:-55 ℃ ~ +150 ℃

三、产品特点与优势

  • 低导通电阻:在 Vgs = 4.5 V 下 RDS(on) = 14 mΩ,对高电流、低压差场合有利,降低导通损耗。
  • 合理的栅电荷:Qg = 16 nC 在 4.5 V 门驱下兼顾开关损耗与驱动能量,适合中高速开关频率应用。
  • 较低的 Crss(122 pF):有利于减少 Miller 效应对开关瞬态的影响,但在高 dV/dt 场合仍需注意栅极驱动抑制。
  • 完整可靠性保证:100% 雪崩能量保证,增强了瞬态过压/能量吸收能力。

四、典型应用场景

  • 同步整流/同步降压(Buck)转换器的高边或低边开关。
  • 电机驱动、DC–DC 电源模块、服务器/通信电源、消费类高电流开关应用。
  • 需要表贴大电流能力且 PCB 散热可控的功率级。

五、设计与热管理建议

  • 封装 TO252-3L 依赖 PCB 铜箔与过孔散热,建议在 MOSFET 底部与大地平面使用较大面积铜箔并配合多孔过孔导热至背面散热层。
  • 额定 Id = 60 A 为器件极限值,实际连续电流能力受 PCB 散热与环境而定,应根据实际温升进行热仿真或实测。
  • 估算栅极驱动功耗:Pg = Qg × Vdrive × fSW。举例:Qg=16 nC,Vdrive=10 V,fSW=500 kHz,则 Pg ≈ 0.08 W(平均),开关损耗与能量更随频率与 dv/dt、di/dt 增加。
  • 为抑制开关尖峰与振荡,建议合理选择门极电阻并在必要时加 R-C 吸收或 TVS 限压。

六、可靠性与合规

  • 器件通过功能可靠性认证并保证 EAS(雪崩能量),提高在瞬态过压或感性负载断开时的安全性。
  • 满足 RoHS 与绿色产品要求,适合要求环保合规的产品线。

七、选型建议

  • 若系统门驱电压为 4.5 V 左右,XR60N04B 在 RDS(on) 与 Qg 之间取得良好平衡,适合作为低电压门驱的功率开关。
  • 对于采用 10–12 V 门驱且追求更低导通损耗的场合,可以比较同族在 Vgs=10 V 下 RDS(on) 的器件;若系统需极低开关损耗且频率极高,应评估 Qg/Crss 对驱动与开关损耗的影响。

总结:XR60N04B 以 40 V/60 A 的电气能力、14 mΩ 的低导通电阻(4.5 V 驱动)和适中的栅电荷,成为中高电流、同步降压和通用功率开关场合的实用选择。合理的 PCB 散热与驱动设计将充分发挥其性能优势。

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
