XR3400AL 产品概述

一、产品简介

XR3400AL 是新锐(XNRUSEMI)推出的一款高单元密度沟槽式 N 沟道 MOSFET,采用 SOT23-3L 小封装。器件针对小功率开关和负载开关场景进行了优化,兼顾较低的导通电阻和良好的开关性能,适合便携式电子、电源管理、负载切换及一般开关应用。产品符合 RoHS 与绿色环保要求,并通过了完整的可靠性认证。

二、主要电气参数(典型/额定)

  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:6 A
  • 导通电阻 RDS(on):23 mΩ @ Vgs = 10 V
  • 最大耗散功率 Pd:1.5 W
  • 阈值电压 Vgs(th):约 0.9 V
  • 总栅极电荷 Qg:4.8 nC @ Vgs = 15 V
  • 输入电容 Ciss:602 pF
  • 反向传输电容 Crss(Miller):42 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT23-3L
    (更多典型值与极限值请参考完整数据手册与封装图)

三、主要特点与优点

  • 低导通电阻:23 mΩ(10 V 驱动)可在小功率应用中降低导通损耗,提高效率。
  • 适度的栅极电荷:Qg = 4.8 nC,切换损耗与驱动功率适中,便于与小功率驱动器或 MCU 驱动接口配合。
  • 小体积封装:SOT23-3L 适合空间受限的设计与表面贴装工艺。
  • 宽温度范围:-55 ℃ ~ +150 ℃ 满足工业级环境的可靠性需求。
  • 环保合规:符合 RoHS 与绿色产品要求,并通过可靠性认证,便于产品认证与长期供应。

四、典型应用场景

  • 低压直流负载开关(如供电路径、外设电源开关)
  • 电池保护与电源管理(便携设备、移动终端)
  • 同步整流或降压转换器的小功率开关元件(低电流段)
  • 反向电流控制、功率切换与负载隔离
  • 小型直流电机驱动与智能开关类应用

五、设计与使用建议

  • 驱动电压:RDS(on) 给定值为 Vgs = 10 V 时测得,若采用 10 V 驱动可获得最低导通损耗;在 4.5 V 或 5 V 驱动下器件仍能工作,但导通电阻会显著增大,应评估功耗与温升。
  • 高端/低端开关选择:作为 N 沟道器件,优先用于低端(接地侧)开关;若用于高端(高侧)开关需配合升压栅极驱动或采用栅极驱动器/驱动电荷泵。
  • 开关损耗评估:栅极驱动功率近似为 Pgate ≈ Qg × Vdrive × fSW。例:在 Vdrive = 10 V、fSW = 100 kHz 时,Pgate ≈ 4.8 nC × 10 V × 100 kHz = 4.8 mW(可忽略);但在高频或频繁开关场合应考虑开关损耗与器件发热。
  • Miller 效应:Crss = 42 pF,会影响上升/下降沿与抗干扰能力。驱动电路应考虑合适的栅极电阻和抑制振铃的 RC 网络以改善开关过渡。
  • 热设计:封装为 SOT23-3L,Pd = 1.5 W(在规定散热条件下),实际应用中需做好 PCB 散热(增加铜箔、散热过孔、接地/电源平面扩展)以降低结温,防止热降额。
  • 保护措施:在带感性负载时建议并联 TVS 或二极管、使用减幅网络(RC)和合适的熔断/限流措施,避免瞬态电压损伤器件。

六、封装与可靠性

  • 封装型号:SOT23-3L,适合自动化贴片与紧凑型 PCB 布局。
  • 引脚与封装图请参见正式数据手册,建议在 PCB 设计阶段采用加大散热铜箔和多层过孔连通散热层的做法。
  • 可靠性:产品通过全功能可靠性认证,适合长期量产使用。符合 RoHS 与环保要求。

七、订购信息与技术支持

  • 型号:XR3400AL(XNRUSEMI / 新锐)
  • 标准封装:SOT23-3L,单只包装或带卷盘供选。

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
