WSP6946 产品概述

一、产品基本信息

WSP6946是WINSOK(微硕)推出的双N沟道场效应管(MOSFET) 器件,采用SOP-8表面贴装封装,集成2个独立的N沟道MOSFET单元,定位为中低压、中等电流场景的通用型功率器件,可满足工业控制、消费电子等领域的基础功率控制需求。

二、核心电气参数

WSP6946的关键参数围绕中低压应用优化,核心指标如下:

  • 漏源电压(Vdss):最大60V,支持12V/24V等中低压系统;
  • 连续漏极电流(Id):额定6.5A,可稳定承载中等功率负载;
  • 导通电阻(RDS(on)):50mΩ(@Vgs=4.5V,Id=4A),低导通电阻降低功率损耗,提升电路效率;
  • 耗散功率(Pd):2.5W,满足基础功率耗散需求;
  • 阈值电压(Vgs(th)):3V(@Id=250uA),栅极驱动门槛低,可直接由普通MCU逻辑电平驱动;
  • 栅极电荷量(Qg):20nC(@Vgs=10V),开关速度较快,适合高频开关应用;
  • 电容参数:输入电容Ciss=940pF,反向传输电容Crss=64pF,输出电容Coss=91pF,电容特性匹配开关电路设计。

三、封装与应用场景

3.1 封装特性

产品采用SOP-8表面贴装封装,具备以下特点:

  • 双管集成设计,节省PCB布局空间,替代2个独立MOSFET;
  • 引脚布局合理,便于电路布线与散热设计;
  • 兼容自动化生产,降低焊接成本与生产难度。

3.2 典型应用

结合参数特性,WSP6946适用于以下场景:

  1. 低功耗电源转换:DC-DC降压/升压电路(如5V转12V、12V转5V);
  2. 电池保护电路:便携式设备(移动电源、智能手环)的过充/过放保护;
  3. 小功率电机驱动:玩具电机、小型风扇、微型泵的驱动控制;
  4. LED驱动:小功率LED背光、指示灯的恒流/恒压驱动;
  5. 负载开关:电子设备的电源通断控制(如MCU控制的负载切换)。

四、性能优势

WSP6946在同类产品中具备明显优势:

  1. 低栅压导通性能:4.5V栅压下即可实现50mΩ低导通电阻,无需额外栅极升压电路,简化驱动设计;
  2. 宽温可靠性:工作温度范围-55℃~+150℃,符合工业级温度要求,适应户外、车载(低温场景)等 harsh 环境;
  3. 集成化省空间:双N沟道封装于SOP-8,减少器件数量与PCB面积,降低系统成本;
  4. 开关效率较高:栅极电荷与电容参数匹配,开关损耗低,提升整体电路效率;
  5. 驱动兼容性强:阈值电压3V,可直接由5V逻辑电平驱动,无需电平转换。

五、可靠性与适用范围

WSP6946的可靠性设计满足:

  • 长期工作温度稳定性,可在极端环境下持续运行;
  • 阈值电压一致性好,批量应用时性能波动小;
  • 电流与功率参数匹配,避免过载损坏。

该器件适用于消费电子、工业控制、汽车电子(低温场景)、通信设备等领域的中低压功率控制需求,是基础功率电路的可靠选择。

总结:WSP6946以低导通电阻、宽温范围、集成化设计为核心优势,平衡了性能与成本,适合多种中低压中等电流的开关与功率控制场景,是批量应用的理想器件。

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
