XR3400A 产品概述

一、产品简介

XR3400A 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道 MOSFET,采用小型 SOT23 封装,专为小功率开关与负载开关应用优化。器件在 30V 漏源耐压下提供优异的导通特性与开关性能,兼容 RoHS 与绿色环保要求,适合移动设备、电源管理与继电保护等对体积与效率有较高要求的场合。

二、主要参数概览

  • 类型:N 沟道沟槽 MOSFET(单个)
  • 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
  • 耗散功率 Pd:1.5 W(封装与环境依赖)
  • 阈值电压 Vgs(th):0.9 V(典型)
  • 栅极总电荷 Qg:4.8 nC @ Vgs = 15 V
  • 输入电容 Ciss:602 pF;反向传输电容 Crss:42 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT23

三、关键特性与优势

  • 低导通电阻:在 Vgs = 10 V 条件下 RDS(on) 仅 23 mΩ,可显著降低导通损耗,提高系统效率。
  • 低门限电压:Vgs(th) ≈ 0.9 V,利于在较低电压条件下启动导通。为获得标称 RDS(on),推荐驱动到 10 V。
  • 良好开关性能:适中的 Qg(4.8 nC@15 V)和平衡的 Ciss/Crss,使其在开关频率不太高的电源及负载切换应用中表现稳定。
  • 小尺寸封装:SOT23 适合空间受限的应用,便于表贴装配与自动化生产。

四、典型应用

  • 移动设备电源负载开关、智能手机与平板的电源切换
  • 低功率 DC-DC 转换器的同步/非同步开关器件
  • 电池保护与电源路径管理(电流限制、倒灌保护)
  • 小型继电/驱动应用及消费类电子设备的通断控制

五、使用与布局建议

  • 封装 Pd 受 PCB 冷却能力影响显著,建议在 SOT23 下方与周围使用较大铜面和散热过孔以提升热耗散。
  • 最短和最宽的走线以降低导通路径上的电阻与寄生电感,尤其是源-漏回路。
  • 驱动建议:为达到标称 RDS(on),栅极驱动电压应接近 10 V;若驱动电压受限,应进行实际 RDS(on) 测试并评估损耗。
  • 在快速开关场合加入合适的栅极电阻以抑制振铃;对感性负载添加缓冲/吸收元件以保护器件。
  • 裸片与焊接前避免静电损伤,建议在生产与测试中采用 ESD 保护措施。

六、可靠性与合规

XR3400A 通过严格的功能可靠性验证,工作温度范围覆盖 -55 ℃ 到 +150 ℃,并符合 RoHS 与绿色产品规范。为保证长期可靠性,建议在器件安全工作区(SOA)与热习性范围内使用,并参考完整版数据手册进行电气绝对最大额定值与热阻计算。

七、封装与选型提示

SOT23 小封装便于高密度布板,但限制了片上散热能力。选型时请结合实际工作电流、占空比与 PCB 散热设计进行功耗与结温评估。有关引脚定义、典型电路和更多电气特性,请参阅 XR3400A 完整数据手册或联系 XNRUSEMI(新锐)技术支持。

Sourcing availability signal

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
