XR7002KW 产品概述

一、产品简介

XR7002KW 是 XNRUSEMI(新锐)推出的一款小封装、低栅极电荷的双 N 沟道 MOSFET(SOT363 封装)。器件耐压 60V,适合电池供电与便携式系统中作为开关与功率控制元件使用。采用先进沟槽(trench)工艺,兼顾较低的导通阻抗与小的门极电容,利于快速切换与低驱动损耗。产品通过无铅(RoHS)认证,符合现代环保要求。

二、主要电气参数

  • 型号:XR7002KW(双 N 沟道)
  • 漏-源电压 Vdss:60 V
  • 连续漏极电流 Id:200 mA
  • 导通电阻 RDS(on):典型 1.6 Ω @ VGS = 10 V
    • 规格保证:RDS(on) < 2.1 Ω @ VGS = 10 V;RDS(on) < 2.7 Ω @ VGS = 4.5 V
  • 阈值电压 VGS(th):约 1.7 V
  • 栅极总电荷 Qg:1.7 nC @ VGS = 10 V
  • 输入电容 Ciss:28 pF
  • 反向传输电容 Crss(Cgd):4 pF
  • 功耗 Pd:380 mW
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOT363(小体积,6 引脚)
  • 驱动接口:直接兼容 TTL/CMOS 逻辑电平
  • 环保:无铅 / RoHS 认证

三、特色与优势

  • 低栅极电荷(Qg 仅 1.7 nC),在驱动能力有限的场合(如 MCU 直接驱动或电池供电系统)可实现较快开关和低开关损耗。
  • 先进沟槽技术使得在较高耐压条件下仍能保持较好的 RDS(on) 性能,适合 60V 级别的低功率开关应用。
  • 小封装(SOT363)节省 PCB 面积,适合空间受限的便携设备与模块化电源设计。
  • 逻辑电平兼容,VGS(th) 约 1.7V,能在较低驱动电压下导通(但在 3.3V 下 RDS(on) 会较高,需评估导通损耗)。

四、典型应用场景

  • 电池供电系统:负载开关、电源路径切换与电源管理模块(PMIC)中的低功率开关。
  • 便携式与物联网终端:用于驱动继电器、小电机、LED 阵列或作为端口保护开关。
  • 开关电源的辅助开关、隔离控制以及低压侧开关场合。
  • 直接逻辑电平接口的开关控制:TTL/CMOS 驱动兼容,适合 MCU 直接控制(设计时注意 VGS 与 RDS(on) 的匹配)。

五、设计与应用建议

  • 驱动电压选择:要达到较低的导通阻抗,应优先使用 VGS = 10 V;若系统仅有 4.5 V 驱动,器件仍可工作,但 RDS(on) 会增加(规格保证 <2.7 Ω);在 3.3 V 或更低逻辑下需评估开关及导通损耗是否可接受。
  • 热设计:器件 Pd = 380 mW,实际允许功耗受 PCB 散热与环境温度限制。举例:在 Id = 200 mA、RDS(on) = 1.6 Ω 时,器件损耗约 64 mW(I^2·R),在此条件下工作裕度良好;但在更高阻抗或持续高温环境下应考虑散热和电流限流。
  • 开关速度与 EMI:低 Qg 与较小 Ciss 有利于快速切换并降低开关损耗,但在快速边沿情况下可能带来更多 EMI,建议适当增加门极阻抗或 RC 缓冲以抑制振铃。
  • PCB 布局:由于为小型 SOT363 封装,应优化铜箔散热面积与走线,必要时在器件下方或相邻区域设计散热铜铺,以提高热耗散能力。
  • 引脚与功能确认:XR7002KW 为双管封装,请在设计前确认完整数据手册中的引脚定义、极性与内部连接关系,以避免误连。

六、采购与可靠性

  • 封装:SOT363,便于表面贴装与自动化生产。
  • 环保与认证:无铅、符合 RoHS 要求。
  • 建议在量产前获取完整数据手册与样品进行电气、热特性与寿命验证,特别是用于关键电源路径或长寿命设备时。

总结:XR7002KW 面向需要 60V 耐压、低驱动功耗与小体积封装的低功率开关场合,兼顾了较低的栅极电荷与可接受的导通电阻,是电池供电与便携电子产品中常用的双 N 沟道 MOSFET 选择。为保证设计可靠性,请参考完整规格书并在目标应用下进行评估与测试。

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.
