XR304 产品概述

一、简介

XR304 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式双路 N 沟道 MOSFET,封装为 PDFN3333-8L。器件针对同步降压转换器及高频开关电源的功率级优化设计,在导通电阻与栅极电荷之间取得良好平衡,适用于要求高效率、小封装的电源、负载开关及电机驱动等场景。产品符合 RoHS 与绿色产品要求,100% 保证雪崩耐量(EAS),并通过完整的功能可靠性认证。

二、主要规格

  • 器件类型:双路 N 沟道 MOSFET(2 个 N 沟道)
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:20 A(单管额定)
  • 导通电阻 RDS(on):20 mΩ @ Vgs = 10 V
  • 耗散功率 Pd:6 W(封装限制)
  • 栅阈电压 Vgs(th):2.5 V(典型)
  • 总栅极电荷 Qg:5.2 nC
  • 输入电容 Ciss:490 pF
  • 反向传输电容 Crss:61 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:PDFN3333-8L(3.3 mm × 3.3 mm,8 引脚)
  • 认证与特性:RoHS、100% EAS 保证、完整功能可靠性认证

三、关键特性

  • 低导通损耗:在 10 V 驱动电压下,RDS(on) 典型值为 20 mΩ,适合功率级作为高侧或低侧开关使用,能在中小电流条件下维持较低的导通损耗。
  • 适中开关损耗:Qg = 5.2 nC、Ciss = 490 pF 和 Crss = 61 pF,表示在高频开关(几百 kHz)下具有可控的栅极驱动能量消耗和较小的米勒效应。
  • 小型封装,高单元密度:PDFN3333-8L 提供较小的 PCB 占用面积与良好的散热贴合性能,适合空间受限的电源模块。
  • 强化可靠性:100% 雪崩耐量测试与完整功能可靠性认证,适合对抗负载瞬态或开路条件下可能出现的应力情况。
  • 宽温度范围:-55 ℃ 至 +150 ℃,适应工业级工作环境。

四、典型应用

  • 同步降压(buck)转换器的高侧或低侧开关晶体管
  • 多相电源模块与笔记本/嵌入式系统的电源管理
  • 负载开关与电源隔离电路
  • 小型电机驱动与驱动器功率级
  • 汽车、工业控制中 30 V 以内的功率开关应用(需按系统级可靠性评估)

五、封装与 PCB 布局建议

  • PDFN3333-8L 为紧凑型 DFN/PDN 结构,建议在 PCB 上为底部热垫设计大面积铜箔并通过多盲孔或过孔连接到内部或背面散热层,以降低结-壳温升。
  • 开关结点走线应尽量短且宽,减小寄生电感,特别是高侧与低侧之间的回流路径;栅极驱动回路应使用紧凑布局,避免长走线引起振荡。
  • 在高频开关应用中,栅极驱动端建议并联小阻尼电阻(10–47 Ω)以抑制过冲;在空间允许时添加 RC 缓冲或 TVS 保护提高可靠性。
  • 串联源/漏侧电流检测或分流电阻时,注意其对热分布的影响及功耗能力。

六、热管理与可靠性

  • 标称耗散功率 6 W 为封装在特定热阻条件下的散热能力指标,实际可持续电流受 PCB 散热设计、环境温度及热阻影响。大电流工作时应以实际结温为准进行热仿真与测试验证。
  • 由于器件 100% 提供雪崩耐量(EAS),在出现负载突变或开路条件时具备更高的单脉冲耐受能力,但不应依赖雪崩能力作为常态保护手段,应配合合适的系统过流/过压保护。
  • 长期可靠性与温度循环性能已通过完整功能认证,适合工业级应用,但在汽车级或更严苛环境中,请参考厂方的详细可靠性报告和使用规范。

七、选型与使用要点

  • 驱动电压:为保证标称 RDS(on),建议在 10 V 栅压下使用;在 5 V 驱动下可工作但导通电阻会增加,需评估功耗。
  • 开关速度与 EMI:Qg 和 Crss 数值适中,能在数百 kHz 的切换频率下实现较好效率;若要提高开关速度需注意 EMI 并采取合适的滤波与布局措施。
  • 双路设计优势:封装内含两颗 N 沟道器件,适合在单模块中实现半桥或双路开关,简化 BOM 管理与布局。
  • 考虑安全裕量:设计时对电流与温升要预留裕量,避免长期工作在封装极限功耗附近。

八、结论

XR304 以其低 RDS(on)、适中的栅极电荷与小体积封装,为同步降压转换器和高密度电源设计提供了平衡的性能方案。适配 30 V 以内、20 A 级别的应用场景,结合合理的 PCB 散热和栅极驱动设计,可在效率与可靠性之间取得良好折衷。选择时请根据系统驱动电压、开关频率和热设计进行全面评估,必要时参考厂方数据手册和热特性曲线以完成最终验证。

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.
