XR5N10Q — 100V SOT89-3L 高密度沟槽式N沟道MOSFET 产品概述

一、产品简介

XR5N10Q(品牌:XNRUSEMI 新锐)是一款面向同步降压和开关电源等中高压、高密度开关场合的沟槽式N沟道MOSFET。器件在SOT89-3L小封装中提供了较低的导通电阻和适中的栅极电荷,兼顾导通损耗与开关损耗,是对空间、成本和性能有综合要求的电源设计的理想选择。符合RoHS与绿色环保要求,100%保证雪崩能量,具备完整功能可靠性认证,适合量产应用。

二、主要电气参数(典型/额定)

  • 类型:N沟道功率MOSFET
  • 漏源耐压 Vdss:100 V
  • 连续漏极电流 Id:5 A
  • 导通电阻 RDS(on):150 mΩ @ Vgs = 10 V
  • 阈值电压 Vgs(th):2.5 V(典型触发门限)
  • 总栅极电荷 Qg:26.2 nC @ Vgs = 10 V(用于评估驱动需求与开关损耗)
  • 输入电容 Ciss:1.023 nF
  • 输出电容 Coss:40 pF
  • 反向传输电容 Crss(Crss/Crss):25 pF
  • 耗散功率 Pd:16.4 W(在指定环境与散热条件下)
  • 工作温度范围:-55 ℃ 至 +150 ℃

三、主要特性与优势

  • 低导通电阻与适中栅极电荷:150 mΩ 的导通电阻在 SOT89 小封装中兼顾了导通损耗;26.2 nC 的栅极电荷在需要较低驱动电流的驱动器时表现良好。
  • 100V耐压:适合常见的48V总线或高压侧开关应用。
  • 小体积封装:SOT89-3L 占板面积小,适合对面积敏感的应用,并利于自动贴片生产。
  • 完整可靠性保证:100% 雪崩能量保证与功能可靠性认证,适合要求稳健性的产品线。
  • 环保合规:符合RoHS和绿色产品要求,便于后续产品认证与量产。

四、典型应用场景

  • 同步降压(synchronous buck)转换器的高侧或低侧开关管(依据电路拓扑与驱动)
  • 中小功率开关电源(SMPS)和电源管理模块
  • 电池供电系统与充电管理电路
  • DC-DC转换、负载开关和反向电流控制场合
  • 需要雪崩能量承受能力的瞬态保护场合

五、设计与使用建议

  • 驱动电压:器件标称 RDS(on) 在 Vgs = 10 V 时给出,若驱动电压低于 10 V(如 5 V 逻辑驱动),导通电阻将显著上升,应根据实际Vgs重新评估导通损耗;推荐使用合适的门极驱动器以提供快速、稳定的栅极电压。
  • 开关损耗评估:总栅极电荷 Qg = 26.2 nC 在高频切换时会带来较大的驱动能量消耗(Edrive ∝ Qg·Vdrive),需为驱动器与驱动路径计算功耗并考虑门阻以控制振铃。
  • 直通与开关平衡:Ciss/Coss/Crss 参数用于估算开关瞬态和回灌能量;在高 dv/dt 场合注意 Crss 导致的米勒效应,必要时采用米勒电阻或栅极缓冲。
  • 散热管理:器件在 SOT89 封装下 Pd = 16.4 W(在理想散热条件下),实际布局必须考虑PCB铜箔面积、过孔和散热路径以降低结温;在高电流或持续开关工作下建议增大散热面积或采取热沉方案。
  • 保护与可靠性:建议在输入端或开关节点增加 TVS、RC缓冲或能量吸收网络以降低瞬态应力,利用合适的熔断与保护电路避免极限工况带来损坏。

六、封装与焊接注意

  • 封装:SOT89-3L,适合表面贴装工艺。
  • 焊接:遵循标准回流焊工艺曲线,避免超过器件最大结温与封装热应力;焊盘设计应兼顾机械强度与热传导,推荐扩大散热铜箔与多层过孔连接散热层。

七、可靠性与合规

  • 100% 雪崩能量保证,适合存在能量回灌或高能量瞬态的电路。
  • 满足RoHS与绿色环保要求,适用于多区域产品认证的环境与生态合规要求。
  • 完整功能可靠性认证说明器件已通过必要的应力与寿命评估,适合商用与工业级量产需求。

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
