WSP4447 P沟道场效应管(MOSFET)产品概述

WSP4447是WINSOK微硕推出的一款P沟道增强型MOSFET,采用SOP-8表面贴装封装,以紧凑体积实现中功率开关与电源管理功能,适配消费电子、便携式设备等多场景需求。

一、产品基本信息

WSP4447属于单管P沟道MOSFET,核心定位为低导通损耗、宽温适应性的中功率器件,基本信息如下:

  • 品牌:WINSOK(微硕)
  • 类型:P沟道增强型MOSFET
  • 封装:SOP-8(表面贴装,8引脚)
  • 单管包装:1个/件
  • 核心应用方向:负载开关、电源管理、小型电机驱动等

二、关键电气参数解析

WSP4447的电气参数围绕“功率效率”与“开关性能”平衡设计,核心参数及意义如下:

2.1 电压与电流规格

  • 漏源电压(Vdss):40V(绝对最大额定值),支持12V、24V等低电压系统稳定工作,避免过压击穿;
  • 连续漏极电流(Id):11A(结温Tj≤25℃时连续额定值),覆盖10A以内小型负载(如直流电机、电源模块);
  • 导通电阻(RDS(on)):13mΩ@10V/13A(测试条件:Vgs=10V、Id=13A),低导通电阻直接降低导通损耗,提升电池供电设备续航;
  • 阈值电压(Vgs(th)):1.4V(典型值),适配3.3V、5V常见控制电平,简化驱动电路设计。

2.2 开关与电容特性

  • 栅极电荷量(Qg):32nC@10V(测试条件:Vgs=10V、Id=13A),中速开关范围,平衡开关速度与驱动功耗;
  • 电容参数:输入电容(Ciss)1.5nF@15V、反向传输电容(Crss)180pF@15V、输出电容(Coss)235pF@15V,平衡开关速度与EMI控制;
  • 耗散功率(Pd):2W(结温Tj=25℃额定值),结合SOP-8封装散热能力,支撑中功率负载连续工作。

三、封装与散热特性

WSP4447采用SOP-8封装,具备三大优势:

  1. 体积紧凑:PCB占用面积约6mm×5mm,适配手机、智能手环等便携式设备小型化需求;
  2. 散热效率:引脚与PCB热传导路径清晰,配合Pd=2W额定功率,满足结温范围(-55℃~+150℃)散热;
  3. 工艺兼容:支持回流焊、波峰焊等常规表面贴装工艺,适配自动化生产。

四、典型应用场景

WSP4447参数特性使其在多领域实用:

  • 便携式设备电源管理:手机、平板的电池负载开关(P沟道低侧开关,源极接电池正极);
  • 小型电源模块:DC-DC同步整流(低侧开关)、USB充电器过流保护;
  • 小型电机驱动:低功率直流电机(玩具电机、小型风扇)驱动;
  • 工业辅助电路:-55℃~+150℃宽温,适配户外设备(太阳能路灯控制器)。

五、核心竞争优势

与同封装同功率级竞品相比,WSP4447优势突出:

  1. 低导通损耗:13mΩ RDS(on)比同类产品低10%~15%,提升效率;
  2. 宽温可靠性:-55℃~+150℃结温范围,覆盖工业与消费级极端环境;
  3. 驱动兼容:1.4V低阈值,无需升压即可适配3.3V/5V控制;
  4. 成本效益:单管成本适中,适合批量应用于消费电子。

六、可靠性与环境适应性

WSP4447符合多项可靠性标准:

  • 温度覆盖:-55℃(低温存储)~+150℃(结温工作),满足车载、户外场景;
  • 封装可靠:SOP-8抗振动、冲击,符合IPC-J-STD-020焊接标准;
  • 参数一致:批次间偏差≤5%,提升终端产品稳定性。

综上,WSP4447是平衡效率、体积与可靠性的P沟道MOSFET,适用于成本敏感、空间紧凑且需宽温工作的中功率场景。

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
