XRS8N10Q 产品概述

一、概述

XRS8N10Q 是新锐(XNRUSEMI)推出的一款 100V 等级 N 沟道 MOSFET,采用 Split Gate Trench MOSFET 技术并封装于 SOT-89-3。该器件针对低导通电阻和高开关效率进行了单元密度优化,兼顾小型封装的散热能力与开关性能,适合中低功率开关电源与电源管理场合。

二、主要参数

  • 类型:N沟道 MOSFET
  • 漏源电压 Vdss:100V
  • 连续漏极电流 Id:6.5A
  • 导通电阻 RDS(on):140 mΩ @ Vgs = 10V
  • 阈值电压 Vgs(th):3V
  • 总栅极电荷 Qg:4.3 nC @ Vgs = 10V
  • 输入电容 Ciss:206 pF
  • 输出电容 Coss:28.9 pF
  • 反向传输电容 Crss:1.4 pF
  • 耗散功率 Pd:2W(封装限值)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT-89-3

三、关键特性与优势

  • Split Gate Trench 结构带来较低的导通损耗,使在中等电流下效率更高。
  • 低总栅电荷(4.3 nC)有利于减小驱动损耗、提升开关速度,适合高频开关应用。
  • 适中的寄生电容(Ciss/Coss/Crss)在开关转换与回收能量时表现均衡,有利于 EMI 控制。
  • SOT-89-3 小封装在体积受限的板级设计中易于布局,同时提供相对较好的散热性能,适合密集电源管理模块。

四、典型应用场景

  • DC-DC 降压/升压转换器的功率开关管
  • 电源管理、负载开关与电池保护电路
  • 适配器与充电器中间功率级
  • 小型逆变与辅助电源模块

五、设计与实用建议

  • 在选择驱动电压时,以 Vgs = 10V 条件下的 RDS(on) 和 Qg 为参考,确保栅极驱动器能提供足够电流以快速切换。
  • 热设计需关注封装 Pd = 2W 的限制,评估 PCB 散热能力与环境温度,必要时增加散热铜箔或热通孔以降低结温。
  • 布局上应尽量缩短功率回路环路,减小寄生电感与电阻,尤其是在高频 DC-DC 应用中;栅极走线要短且并加阻尼以抑制振铃。
  • 评估器件在峰值电流与短时脉冲条件下的热应力,使用 I^2·R 损耗估算稳态和瞬态发热。

六、可靠性与选型注意

  • 工作温度范围宽,适合工业级环境。选型时确认系统最大结温与热冗余。
  • 使用时勿超过额定 Vdss(100V),并注意对浪涌与反向恢复能量的保护。
  • 封装和焊接应遵循制造商推荐的回流曲线和湿敏等级,以保证长期可靠性。

七、封装与采购

  • 封装类型:SOT-89-3,适合手板与量产 SMT 工艺。
  • 品牌:XNRUSEMI(新锐)。
  • 单颗器件适用于样机验证,量产时建议与供应商确认批次一致性与可追溯的质量报告。

总结:XRS8N10Q 以其 100V 等级、低 RDS(on) 与低栅电荷的组合,在有限封装空间内为中等电流的开关电源与电源管理提供了性能与成本的平衡方案。设计时重点关注驱动能力与热管理,可在多种电源拓扑中发挥良好效果。

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
