XR15N12 产品概述

XR15N12 是 XNRUSEMI(新锐)推出的一款高性能沟槽 N 沟道 MOSFET,采用 TO252-3L(DPAK)封装,专为同步降压转换器及各类中低功率开关电源和电源管理应用设计。器件在单元密度和开关/导通性能之间取得良好平衡,适合在热受限的板上应用,同时兼顾开关速度与能量耗散控制。

一、主要规格

  • 器件型号:XR15N12
  • 极性:N 沟道(单个)
  • 漏源电压 Vdss:120 V
  • 连续漏极电流 Id:15 A(注:额定电流受散热条件影响)
  • 导通电阻 RDS(on):120 mΩ @ VGS = 10 V
  • 耗散功率 Pd:66 W(额定条件下)
  • 总栅极电荷 Qg:23 nC @ 60 V(典型测试条件)
  • 输入电容 Ciss:1.076 nF
  • 反向传输电容 Crss:20 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO252-3L(DPAK)
  • 其它:符合 RoHS 与绿色产品要求,100% 保证雪崩能量,通过全功能可靠性认证

二、产品特性

  • 高单元密度:沟槽栅结构带来更紧凑的单元布局,在相同芯片面积下提供更低的导通损耗与良好的开关特性。
  • 低 RDS(on) 与合理的 Qg 平衡:120 mΩ@10 V 的导通电阻在 120 V 器件类别中表现良好,同时 23 nC 的栅极电荷利于在高频切换时降低驱动能耗。
  • 开关性能:较小的 Crss(20 pF)有利于降低米勒效应,提高开关边沿可控性,便于在同步整流和高效率转换器中获得较低开关损耗。
  • 耐冲击与可靠性:器件保证 100% 雪崩能量,适合与有感性负载或出现反向瞬态的场合。通过全功能可靠性认证,适合工业级长期运行。
  • 宽温度范围:-55 ℃ 到 +150 ℃ 满足工业级与严苛环境的温度要求。

三、典型应用场景

  • 同步降压(Synchronous Buck)转换器的下桥或上桥开关
  • DC-DC 电源模块、服务器与电信设备电源管理
  • 电机驱动与功率开关(中低功率)
  • LED 驱动与照明电源
  • 电池管理与充放电控制(需考虑电压匹配与散热)
  • 工业控制与功率接口保护电路

四、封装与热管理建议

  • TO252-3L(DPAK)为散热与安装提供了表面贴装的便利,但相比更大的散热封装(如TO-220、TO-247)热阻更高。实际可通过合理的 PCB 散热设计(加大焊盘、增加散热铜箔,或配合底部散热过孔)来提高散热能力。
  • Pd 标称值一般以良好散热条件(如 PCB 大面积散热或理想热沉)为准,实际允许的连续电流需依据 PCB 热阻与环境温度重新评估。
  • 推荐在高功率应用中使用热仿真或实测温升来确定安全工作电流和散热措施。

五、使用注意事项与典型电路建议

  • 驱动电压:RDS(on) 规格在 VGS = 10 V 时给出,若采用逻辑电平驱动(如 VGS = 4.5 V)需评估导通损耗是否满足需求。
  • 栅极驱动与抗振动:推荐在栅极串联小阻(常见 5–22 Ω)以控制 dv/dt、减少振铃并限制瞬态电流。对感性负载,可加 RC 吸收网或 TVS 进行过压保护。
  • 并联使用:多片并联时需注意导通均流,良好的布线和对称散热设计能降低单片过载风险。
  • 开关布局:尽量缩短高 di/dt 回路的走线,减小寄生电感,以降低 EMI 与应力。

六、可靠性与合规性

  • 符合 RoHS/绿色产品要求,适用于环保合规项目。
  • 100% 雪崩能量保证,器件通过了全功能可靠性测试,适合工业和严苛运行环境。
  • 推荐在设计过程中参考器件的 SOA(安全工作区)曲线与热特性,确保长期可靠运行。

七、订购信息与支持

  • 品牌:XNRUSEMI(新锐)
  • 封装:TO252-3L(DPAK)单片封装,适合 SMT 流程。
  • 型号:XR15N12,如需样片或批量采购,请联系渠道或本品牌授权分销商获取最新规格书、可靠性报告及应用资料。技术支持可提供参考电路、布局建议与热设计指导。

总结:XR15N12 在 120 V 电压等级中提供了良好的导通性能、可控的开关特性与工业级可靠性,适合用于同步降压及各类中低功率功率管理场景。设计时应以实际散热条件为依据,优化驱动与 PCB 布局以发挥器件最佳性能。

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.
