XR70N03F N沟道MOSFET产品概述

新锐半导体(XNRUSEMI)推出的XR70N03F是一款针对低电压大电流场景优化的N沟道增强型MOSFET,凭借低导通损耗、宽温度适应性及小封装特性,适用于便携电子、电动工具、电源管理等多领域,是高性价比的功率器件选择。

一、产品基本信息

XR70N03F为N沟道增强型MOSFET,由新锐半导体(XNRUSEMI)研发生产。器件采用PDFN-8L(5×6mm) 表面贴装封装,尺寸紧凑;工作温度范围覆盖**-55℃至+150℃**,满足工业级及部分车载环境的可靠性要求,可在极端温度下稳定工作。

二、核心电气参数解析

XR70N03F的参数围绕“低电压大电流”核心需求设计,关键性能如下:

  1. 耐压与电流能力:漏源击穿电压(Vdss)为30V,连续漏极电流(Id)达70A,可稳定承载中高功率负载(如电动工具电机、DC-DC转换器输出);
  2. 低导通损耗:导通电阻(RDS(on))仅5.2mΩ(测试条件:Vgs=10V,Id=30A),显著降低导通功率损耗(公式:P=I²R),减少散热需求;
  3. 功率与温度:最大耗散功率(Pd)为82.5W,结合宽温范围,可在高温环境下(如电动工具工作时)持续稳定输出;
  4. 栅极与开关特性:阈值电压(Vgs(th))为1.6V,兼容3.3V/5V栅极驱动(无需额外升压电路);栅极电荷量(Qg)60.5nC(Vgs=10V),输入电容(Ciss)2.016nF、反向传输电容(Crss)230pF,开关速度与导通损耗平衡良好,适合中等频率(100kHz~500kHz)应用。

三、封装与散热特性

XR70N03F采用的PDFN-8L(5×6mm)封装具有三大优势:

  • 小体积高密度:5mm×6mm的紧凑尺寸,节省PCB空间,适配笔记本、平板等便携设备的小型化设计;
  • 高效散热:表面贴装封装的热阻经优化,可有效传导82.5W耗散功率,配合PCB铜箔散热即可满足多数应用,无需额外散热片;
  • 工艺兼容性:封装结构抗机械应力,适合回流焊等批量生产工艺,良率稳定。

四、典型应用场景

XR70N03F的参数特性使其适用于以下场景:

  1. 便携电子电源管理:笔记本、平板的DC-DC降压转换器(如12V转5V/3.3V),满足高电流输出需求;
  2. 电动工具驱动:电钻、电动螺丝刀等小型电动工具的电机驱动电路,承载大启动电流;
  3. 电池保护与管理:便携式设备的锂电池保护电路,实现过充、过放、过流保护;
  4. 小型UPS与应急电源:小功率UPS的逆变/整流模块,提供稳定备用电源;
  5. 车载辅助电源:12V车载系统的USB充电、LED照明等小功率负载驱动,适应车载温度环境。

五、产品竞争优势

相较于同等级(30V/70A)MOSFET,XR70N03F具有以下核心优势:

  1. 低导通损耗:5.2mΩ的RDS(on)在同类产品中处于领先水平,DC-DC转换效率可超95%,减少能源浪费;
  2. 宽温可靠性:-55℃~+150℃的工作范围,覆盖工业级应用,降低环境温度对性能的影响;
  3. 驱动简化:1.6V阈值电压兼容主流MCU驱动,无需额外升压电路,减少BOM成本;
  4. 平衡开关性能:Qg与电容参数平衡,兼顾开关速度与导通损耗,适合中等频率应用;
  5. 性价比优势:新锐半导体的量产能力确保器件成本可控,适合中低端便携与工业应用。

XR70N03F通过参数优化与封装设计,为低电压大电流场景提供了高性价比的功率器件解决方案,可满足多数便携电子、电动工具及电源管理的设计需求。

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
