XR4N15L 产品概述

XR4N15L 是 XNRUSEMI(新锐)推出的一款高单元密度沟槽式 N 沟道 MOSFET,针对小功率开关与负载开关场合做了工艺与封装优化。器件在 150V 耐压等级下提供良好的导通性能与开关特性,适用于开关电源、充电器、工业控制与便携电源等多种应用场景。

一 性能与关键参数

  • 类型:沟槽式 N 沟道 MOSFET(单片,1 个)
  • 漏源耐压 Vdss:150 V
  • 连续漏极电流 Id:4 A
  • 导通电阻 RDS(on):245 mΩ @ Vgs = 10 V
  • 功耗耗散 Pd:3 W(封装及散热条件相关)
  • 阈值电压 Vgs(th):2 V(典型测试条件)
  • 门极总电荷 Qg:8.2 nC(典型测试条件,如 Vds = 75 V)
  • 输入电容 Ciss:450 pF;反向传输电容 Crss:14 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃

二 封装与热特性

  • 封装:SOT23-3L,小型低成本封装,便于表面贴装与高密度 PCB 设计。
  • 热管理:SOT23-3L 封装限制造成的散热能力有限,器件 Pd = 3 W 为理想热阻下的最大耗散。实际应用中需通过合理的铜箔面积、散热层与过孔(thermal vias)来增强热扩散,确保在高功率与高环境温度下可靠工作。

三 优势与适用场景

  • 优势:高单元密度沟槽工艺带来较低的导通电阻与较小的开关损耗;中等门极电荷量便于驱动,Crss 值较小有利于减小米勒效应。
  • 典型应用:
    • 低功率开关电源的低侧开关或续流开关
    • 便携设备与电池管理的负载开关
    • 线性/开关混合电路中的保护或切换器件
    • 小型电机驱动、电源轨切换、辅助电路开关

四 设计与使用建议

  • 栅极驱动:RDS(on) 标称值在 Vgs = 10 V 下给出,若使用 5 V 或更低栅压驱动,应评估导通电阻上升与功耗影响。Vgs(th) ≈ 2 V 表明不能将其视为严格的逻辑电平 MOSFET,在低电压驱动下需谨慎。
  • 开关速度与干扰:Qg = 8.2 nC 与 Ciss/Crss 表明开关速度适中。若需抑制振铃或 EMI,可并联栅极电阻(10–100 Ω)或增加 RC 缓冲网络;必要时在 Drain–Source 端采用缓冲电阻或 RC 吸收电路。
  • 热保护:在高负载或连续导通时通过 PCB 铜箔加大散热面积,并在布板时尽量缩短大电流走线,增加过孔实现多层散热。
  • 持续电流:Id = 4 A 为器件在一定温升与封装限制下的持续电流能力,实际可承载电流应按工作温度、散热条件与脉冲因数修正。

五 合规性与可靠性

XR4N15L 符合 RoHS 与绿色产品要求,并通过了全功能可靠性认证,适用于对环境与可靠性有一定要求的工业与民用产品。器件工作温度覆盖 -55 ℃ 至 +150 ℃,满足严苛环境下的可靠性需求。

六 典型电路参考(简要)

  • 作为低侧开关:源接地,漏接负载负端,栅极通过驱动 IC 或 MCU 驱动(建议加栅极限流电阻与逻辑电平匹配)。
  • 作为高压开关:在高压侧或离线电源中使用时,注意 Vds 峰值、开关过渡瞬态与能量吸收设计,必要时并联 TVS 或 RC 吸收网络。

总结:XR4N15L 在 150V 耐压区间内,以 SOT23-3L 小体积实现了平衡的导通与开关性能,适合多数小功率开关和负载开关应用。设计时需关注栅压驱动、散热与开关过渡保护,以发挥器件最优性能。若需更详细的电气特性曲线、封装尺寸与参考电路图,请提供需求以便进一步补充。

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
