XR1005L 产品概述

一、简介

XR1005L 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道 MOSFET,封装为 SOT23-3L。该器件针对小功率开关与负载开关应用进行了优化,在导通电阻与开关效率之间取得良好平衡,同时满足 RoHS 与绿色产品要求,并通过了全功能可靠性认证,适合要求体积小、成本低且可靠性高的应用场合。

二、主要参数

  • 类型:N 沟道 MOSFET(沟槽式)
  • 漏源电压 Vdss:100 V
  • 连续漏极电流 Id:5 A(须依据封装热性能与散热条件进行退载)
  • 导通电阻 RDS(on):120 mΩ @ Vgs = 10 V
  • 最大耗散功率 Pd:2.5 W(SOT23-3L 封装)
  • 阈值电压 Vgs(th):2.5 V
  • 总栅电荷 Qg:18 nC @ Vgs=50 V(注:标称条件下测得)
  • 输入电容 Ciss:765 pF
  • 反向传输电容 Crss:33 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT23-3L

三、性能亮点

  • 低导通电阻:在 10 V 门极驱动下 RDS(on) 为 120 mΩ,可在中等电流条件下实现较低导通损耗。
  • 较小的栅电荷与电容:Qg=18 nC、Ciss=765 pF,有利于减小驱动功耗与提高开关速度,适合高频开关或对开关损耗敏感的系统。
  • 宽电压与温度范围:100 V 的耐压能力适用于多数工业与汽车附近中等电压域,-55~150 ℃ 的工作范围满足严苛环境需求。
  • 小尺寸封装:SOT23-3L 有利于空间受限的电路板布局和低成本量产。

四、典型应用

  • 小功率 DC-DC 开关、反向保护、负载开关与电源管理;
  • 机顶盒、家电、照明驱动等对体积与成本敏感的电子设备;
  • 高压侧低到中等电流转换场景,例如从 48 V 或 24 V 到低电压的开关元件。

五、设计与布局建议

  • 热设计与电流退载:SOT23-3L 的耗散功率仅 2.5 W,标称 Id=5A 在无额外散热的情况下通常不可持续工作。举例:若持续电流为 5 A,则导通损耗约 I^2·R ≈ 3.0 W(超过 Pd),必须通过 PCB 铜箔加厚或多层散热来退载,或限制工作电流/占空比。建议在目标工作条件下评估结温并按 datasheet 给出的热阻进行退载计算。
  • 栅极驱动:器件在 Vgs=10 V 时 RDS(on) 最优,若系统使用 10 V 驱动能获得最低导通损耗;阈值约 2.5 V,5 V 驱动下导通电阻会上升,应结合实际电流选择驱动电压。
  • 开关速度与驱动器:Qg=18 nC,若希望在 100 ns 完成 10 V 的开关,峰值栅电流约为 Qg / t ≈ 0.18 A,建议选配能提供瞬态电流的驱动器并适当串联栅阻(例如 10–100 Ω)以控制振铃和 EMI。平均栅驱动电流约等于 Qg·f(f 为开关频率),用于估算驱动器功耗。
  • 布局要点:短低阻的源回流路径、充足的铜面积用于散热、靠近 MOSFET 放置驱动和退耦电容,减小寄生电感与环路面积。

六、可靠性与合规

XR1005L 满足 RoHS 与绿色产品规范,并通过厂方的全功能可靠性认证。SOT23-3L 小封装便于自动化贴装与高良率生产,但在焊接工艺(回流温度)与潮湿敏感性方面应遵循供应商提供的装配指南。

七、使用注意

  • 请参阅完整数据手册确认 Vgs 最大额定值、脉冲能力、热阻等关键极限参数;设计时按实际工作点对 Id、Pd 进行热降额计算。
  • 在高频或高电流切换时,关注 Crss 导致的米勒效应和栅−漏耦合,对驱动策略进行优化以避免误触发或过大开关损耗。

总结:XR1005L 在 SOT23-3L 小封装中提供了 100 V 耐压与较低 RDS(on) 的良好组合,适合空间受限、需兼顾效率与成本的小功率开关与负载开关场景。但在设计时需特别注意封装热限制与栅极驱动匹配,以保证可靠运行。若需进一步的电气特性曲线或封装尺寸图,请索取完整数据手册。

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.
