  • 额外特性:符合 RoHS/绿色要求;100% 雪崩能量保证;具备完整功能可靠性认证

二、核心特性与优势

XR190N04T 以低导通电阻与高电流能力为核心,针对高效能开关应用进行优化:

  • 低 RDS(on)(2.7 mΩ @10 V)显著降低导通损耗,适合大电流路径,有利于提高系统效率与降低发热。
  • 190 A 的连续漏极电流能力配合 TO-220AB 便于在中功率至大功率场合实现可靠的散热与安装。
  • 相对适中的栅极电荷(Qg = 80 nC @20 V)在提供低导通电阻的同时,将开关损耗与驱动需求控制在可接受范围,有利于同步降压转换器中开关频率与效率的平衡。
  • Ciss 与 Crss 指标反映了开关过程中 Miller 效应与驱动响应,可用于精确评估开关过冲、切换损耗及驱动器选型。
  • 器件通过 100% 雪崩能量保证和完整的可靠性认证,适合对开关应力与长期可靠性有较高要求的设计。

三、典型应用场景

  • 同步降压(Buck)转换器的高侧或低侧开关管
  • 服务器与电信电源、点-of-load(POL)转换器
  • 电机驱动、功率管理模块与高效率整流电路
  • 需较高浪涌电流与良好热管理的功率开关场合

四、设计与使用建议

  • 散热:Pd = 61 W 为器件在良好散热条件下的参考耗散,实际应用中请依据系统热阻与散热方式(散热片、风冷或强制风冷)计算结温,确保在额定工作温度范围内运行。
  • 驱动:推荐的栅极驱动电压为接近 10 V 以实现标称 RDS(on);若采用更高驱动电压,需权衡器件安全极限与驱动器能力。为抑制开关振铃与过冲,可在栅极串联适当的阻尼电阻,并在必要处增加 RC 吸收或缓冲网络。
  • 布局:减小栅极-源回路与功率回路的环路面积,缩短大电流走线,优化散热铜箔面积与过孔布局,尽量降低寄生电感以减少开关应力。
  • 开关性能调优:考虑 Crss(317 pF)带来的 Miller 效应,在高 dV/dt 场合通过驱动策略与合适的阻尼组件控制开关过渡,以降低 EMI 与峰值应力。
  • 可靠性:在存在反向恢复能量或高能脉冲情况下,利用器件雪崩保证特性设计保护电路,并进行必要的软启动、限流与过温保护设计。

五、可靠性与合规

XR190N04T 满足 RoHS 与绿色产品规范,生产过程中进行严格的质量控制与功能测试。器件提供 100% 雪崩耐量保证,并通过相关可靠性认证,适用于需长期稳定运行与高可靠性要求的工业与通信电源系统。

总体而言,XR190N04T 以低导通损耗、高电流承载能力与良好开关性能,适合用于各种同步降压与高效率功率转换场合。在实际设计中,合理的驱动、布局与散热处理将最大化器件性能并提升系统可靠性。

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
