WSF40P04 P沟道场效应管产品概述

WSF40P04是WINSOK(微硕)推出的高性能P沟道增强型MOSFET,核心规格为40V耐压、20A连续漏极电流及45W最大耗散功率,采用TO-252贴片封装,适用于低压功率转换、负载开关等场景,具备低导通损耗、宽温稳定等核心优势。

一、产品基本信息

WSF40P04的基础标识清晰反映性能定位:

  • 品牌与类型:WINSOK微硕出品的P沟道MOSFET;
  • 核心参数:漏源电压(Vdss)40V,连续漏极电流(Id)20A,最大耗散功率(Pd)45W;
  • 封装形式:TO-252(DPAK)贴片封装,单管1个装;
  • 工作温度:工业级宽温范围,-55℃至+175℃。

二、核心电气参数解析

关键参数直接决定性能表现,重点解析如下:

  1. 导通损耗与效率:导通电阻RDS(on)=42mΩ(Vgs=10V时),处于同类40V P沟道MOSFET领先水平,显著降低导通功率损耗,提升系统能效;
  2. 驱动特性:阈值电压Vgs(th)=2V,栅极电荷量Qg=20nC(Vgs=10V时),低阈值降低驱动电路设计难度,小Qg值减少开关损耗,提升开关速度;
  3. 电容特性:输入电容Ciss=840pF,反向传输电容Crss=60pF,输出电容Coss=92pF,低Crss抑制米勒效应,优化高频开关稳定性;
  4. 安全裕量:40V耐压+20A连续电流满足低压系统需求,宽温范围覆盖工业、车载等严苛环境。

三、封装与散热特性

TO-252封装具备以下特点:

  • 小型化设计:尺寸紧凑(6.0mm×5.0mm),适配空间受限的小型设备(如便携式电源、微型电机驱动);
  • 散热能力:引脚布局利于PCB敷铜散热,结合45W最大耗散功率,合理散热下可稳定工作于额定功率,避免热失控;
  • 焊接兼容性:支持回流焊工艺,适合自动化生产,提升组装效率。

四、典型应用场景

基于参数特性,典型应用包括:

  1. 低压DC-DC转换:12V/24V系统(如车载充电器、电源适配器),低导通损耗提升转换效率;
  2. 负载开关控制:电池保护电路、便携式设备电源通断(如笔记本、平板PMU),低驱动门槛简化设计;
  3. 小型电机驱动:低压直流/步进电机(如智能家居、小型机器人),20A电流满足动力需求;
  4. 工业控制:宽温适应工业现场温度波动,用于开关量控制、功率调节;
  5. 消费电子PMU:集成优化系统功耗,适配手机、平板等设备。

五、关键性能优势

WSF40P04在同类产品中具备核心优势:

  1. 高能效:低RDS(on)减少导通损耗,适合能效敏感场景;
  2. 易驱动:低Vgs(th)无需高压驱动,降低BOM成本;
  3. 宽温稳定:工业级温度范围,适配严苛环境;
  4. 快速开关:小Qg值提升开关速度,适合高频应用;
  5. 小型化适配:TO-252封装满足设备微型化趋势。

总结而言,WSF40P04是兼顾性能、成本与可靠性的P沟道MOSFET,适用于低压功率场景的多种应用,是电源设计、电机驱动等领域的实用选择。

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
