WST2011 P沟道场效应管产品概述

WST2011是WINSOK(微硕)推出的双P沟道增强型MOSFET,针对低电压、小功率应用场景优化设计,以紧凑封装、低导通损耗和宽温适应性为核心优势,广泛适配便携电子、电源管理等领域的小型化需求。

一、产品定位与核心价值

WST2011聚焦3.3V/5V低电压系统的功率控制,主打“小封装+高效率+易驱动”三大特性:

  • 双P沟道集成于SOT-23-6L封装,节省PCB空间50%以上(对比单管封装);
  • 低导通电阻(115mΩ@2.5V/1A)减少导通损耗,提升电源转换效率;
  • 栅极电荷([email protected])低,开关速度快,适配高频应用。

二、核心电气参数详解

WST2011的参数设计精准匹配低电压场景,关键指标如下:

1. 电压与电流特性

  • 漏源击穿电压(Vdss):20V,满足单节锂电池(3.7V)、5V系统的安全电压范围;
  • 连续漏极电流(Id):3.2A,支持小功率负载(如小型电机、LED阵列)的持续工作;
  • 脉冲漏极电流:结合连续电流可支持瞬时峰值电流(如启动瞬间),适配动态负载需求。

2. 导通与驱动特性

  • 导通电阻(RDS(on)):115mΩ@2.5V/1A(栅极驱动电压2.5V时),导通损耗仅115mW(1A负载下),远低于传统三极管;
  • 阈值电压(Vgs(th)):1.5V@250uA,栅极驱动门槛适中,可直接由3.3V MCU输出驱动,无需额外放大电路;
  • 栅极电荷量(Qg):[email protected],开关过程中栅极所需电荷少,降低驱动功耗,提升开关频率上限。

3. 电容与功率特性

  • 输入/输出/反向传输电容:Ciss=750pF、Coss=95pF、Crss=68pF,低Crss可减少米勒效应,避免开关时误导通;
  • 耗散功率(Pd):1.4W(单管),双管集成后总功率适配小功率应用,无需额外散热片即可稳定工作。

4. 温度适应性

  • 工作温度范围:-55℃~+150℃,覆盖工业级宽温需求,可在极端环境(如户外便携设备、高温车间)稳定运行。

三、封装与引脚配置

WST2011采用SOT-23-6L封装(6脚小外形晶体管封装),尺寸仅2.9mm×1.6mm×1.1mm,具备以下优势:

  • 引脚间距0.95mm,适配高密度PCB布局;
  • 6脚设计支持双P沟道独立/并联使用(可配置为单路大电流或双路独立控制);
  • 表面贴装工艺,兼容自动化生产,降低焊接难度。

四、典型应用场景

WST2011的参数与封装特性决定了其在以下场景的突出表现:

1. 便携电子设备

  • 手机、蓝牙耳机、智能手环的电源路径管理(如电池与外设的通断控制);
  • 可穿戴设备的低功耗负载开关(如传感器供电切换,减少待机电流)。

2. 低电压电源管理

  • 5V转3.3V/1.8V的DC-DC降压电路(作为同步整流管,提升转换效率);
  • 锂电池保护电路的充放电控制(双P沟道实现充放电路径独立控制)。

3. 小功率负载驱动

  • 小型直流电机(玩具电机、智能门锁电机)的低速驱动;
  • LED背光/指示灯的调光控制(通过PWM调节栅极电压,实现亮度线性调节)。

4. 工业控制模块

  • 传感器节点的电源切换(宽温范围适配户外工业场景);
  • 小型继电器的驱动替代(无触点,提升可靠性)。

五、可靠性与选型优势

WST2011通过温度循环、湿度老化、ESD防护等多项可靠性测试,满足RoHS环保要求,选型优势包括:

  • 成本效益:双管集成降低物料成本与PCB面积,减少BOM数量;
  • 设计简化:易驱动特性无需额外驱动电路,缩短研发周期;
  • 性能均衡:低导通损耗与低栅极电荷兼顾效率与开关速度,适配多场景需求。

综上,WST2011是一款针对低电压小功率应用的高性价比双P沟道MOSFET,以紧凑封装、高效性能和宽温适应性,成为便携电子、电源管理等领域的理想选型。

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
