WSP4067是WINSOK(微硕)推出的一款单封装集成1个N沟道与1个P沟道的场效应管(MOSFET),采用SOP-8贴片封装,专为中低功率场景的开关、驱动及功率转换设计,兼具小体积、低损耗与逻辑电平适配性,适用于多种小型化电子设备。
WSP4067的参数设计平衡了功率能力与应用适配性,关键指标如下:
WSP4067采用标准SOP-8贴片封装,尺寸约为3.9mm×4.9mm(引脚间距1.27mm),具备以下优势:
基于参数特性,WSP4067主要适用于以下场景:
作为同步降压/升压电路的互补开关管(N沟道做下管、P沟道做上管),低导通电阻可将转换效率提升至90%以上,适配5V→3.3V、12V→5V等常见电压转换需求。
用于控制小功率负载的通断(如LED灯条、小型直流电机、传感器供电),7.5A连续电流可覆盖多数小负载,逻辑电平驱动无需额外驱动电路,简化电路设计。
互补MOSFET结构适合音频信号的推挽放大,低导通电阻可减少信号失真,适配便携式音频设备(如蓝牙音箱、耳机放大器)的小功率放大需求。
用于便携式设备的充放电控制、过流保护等功能,40V电压余量适配多串锂电池组,低损耗可延长电池续航时间。
WSP4067的设计针对中低功率场景优化,核心优势包括:
若需替换WSP4067,需重点匹配以下参数:
建议优先参考WINSOK官方推荐的替换型号,或咨询原厂技术支持确认兼容性。
以上概述基于公开参数整理,具体应用需结合实际电路需求参考官方 datasheet。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
