XR4N10L — 高性能沟槽N沟道MOSFET产品概述

一、产品简介

XR4N10L 是 XNRUSEMI(新锐)推出的一款高性能沟槽式 N 沟道 MOSFET,额定漏源电压 Vdss 为 100V,连续漏极电流 Id 为 4A,典型导通电阻 RDS(on) 为 120mΩ(Vgs=10V)。封装为 SOT-23-3L,单元密度高、栅极电荷适中,专为中小功率同步降压转换器和开关应用优化。器件符合 RoHS 与绿色环保要求,并通过 100% 雪崩耐量保证及完整功能可靠性认证。

二、主要电气参数(关键值)

  • Vdss:100V
  • Id(连续):4A
  • RDS(on):120mΩ @ Vgs = 10V
  • Vgs(th):约 2V(阈值电压)
  • 总栅极电荷 Qg:14.8nC(测量点注明为 50V)
  • 输入电容 Ciss:655pF;反向传输电容 Crss:24pF
  • 最大耗散功率 Pd:26.6W(注意实际散热依赖封装与 PCB 散热条件)
  • 工作温度范围:-55℃ ~ +150℃

三、典型应用场景

  • 同步降压(Buck)转换器的高端或低端开关
  • DC-DC 电源模块、小功率电源管理
  • 电池供电系统与备用电源切换
  • 小型电机驱动与功率开关应用

四、设计与使用要点

  • 栅极驱动:为了达到标称 RDS(on) 建议 Vgs 驱动至 10V;门槛电压约 2V,低压驱动(如 4.5V)可工作但 RDS(on) 增大,导通损耗上升。
  • 开关损耗与 Qg:Qg=14.8nC 表明在高频开关时栅极驱动能量不可忽视,驱动器需提供足够瞬态电流以控制开关速度与损耗平衡。
  • 散热管理:SOT-23-3L 封装散热受限,数据表 Pd 为在特定散热条件下的额定值;在 PCB 上应铺设大面积散热铜箔并多层过孔导热以降低结温。按 P = I^2·RDS(on) 估算稳态损耗,并进行结温计算与热仿真验证。
  • 布局建议:保持栅极回路短且粗,减小寄生电感;在栅极与驱动之间串联小阻(常见 5–20Ω)以抑制振铃并控制 dV/dt。源极旁并联 100nF 旁路电容以稳定驱动参考。
  • 感性负载保护:器件已做雪崩测试,但在实际感性开关应用中仍建议使用 TVS 或 RC 吸收器以限制过压和能量回流,保护器件并扩展系统可靠性。
  • 引脚与封装:SOT-23-3L 常见引脚排列为 Gate / Drain / Source(请以具体数据手册为准),在布局时把大电流回路放在 PCB 穿孔与大铜箔区。

五、可靠性与合规

  • 100% 雪崩耐量测试保证器件在受冲击时有更高鲁棒性,但不应作为常规能量吸收手段。
  • 符合 RoHS 与绿色产品要求,完成完整功能可靠性认证,适合工业与消费类产品设计。

总结:XR4N10L 在 100V 电压等级的中小功率开关应用中提供了良好的导通性能与开关特性,适合用于同步降压与一般功率开关场景。设计时重点关注栅驱、散热与 PCB 布局以发挥器件最佳性能,必要时参考完整数据手册进行功率与热裕度验证。若需进一步的寄生参数、SOA 曲线或 PCB 散热建议,可提供具体应用拓扑以便给出更针对性的设计建议。

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
