WST3400S N沟道MOSFET产品概述

一、产品基本信息

WST3400S是WINSOK(微硕)推出的1个N沟道增强型MOSFET,专为小功率、低功耗场景设计。该器件采用紧凑的SOT-23封装,具备宽温度工作范围(-55℃~+150℃),可满足消费电子、工业控制等多领域的可靠性要求。核心参数针对低导通损耗与高效开关特性优化,适用于对体积、功耗敏感的便携设备及电源管理系统。

二、核心电气参数详解

1. 电压与电流规格

  • 漏源击穿电压(Vdss):30V,可覆盖5V、12V等常见低压直流电源系统,避免过压损坏;
  • 连续漏极电流(Id):5.6A(25℃下),支持中等功率负载的持续工作,峰值电流能力可应对瞬间负载波动。

2. 导通特性

  • 导通电阻(RDS(on)):45mΩ@2.5V Vgs、4A Id,处于同封装同电压等级器件的领先水平,可显著降低导通损耗(P=I²R),提升系统能效。

3. 开关特性

  • 栅极电荷量(Qg):[email protected] Vgs,低栅极电荷意味着开关过程中驱动功率低、速度快,适合高频应用;
  • 电容参数:输入电容(Ciss)600pF、反向传输电容(Crss)91pF、输出电容(Coss)112pF,优化了开关瞬态损耗,进一步提升效率。

4. 阈值与功率参数

  • 阈值电压(Vgs(th)):1V@250uA Id,低阈值可兼容1.8V、2.5V等低压逻辑电平,降低驱动电路设计难度;
  • 耗散功率(Pd):1W(25℃下),支持额定功率范围内稳定工作,降额设计可扩展至更高功率场景。

三、封装与物理特性

WST3400S采用SOT-23封装,典型尺寸约2.9×2.5×1.1mm,便于高密度PCB布局,可有效缩小终端产品体积。封装材料具备良好热传导性,配合-55℃~+150℃的宽温范围,可在极端环境(如户外设备、工业控制模块)下保持稳定性能,满足可靠性要求。

四、关键性能优势

  1. 低导通损耗:45mΩ的低RDS(on)大幅减少导通功率消耗,尤其适合电池供电的便携设备,延长续航时间;
  2. 高效开关特性:低Qg与优化电容参数降低开关损耗,提升DC-DC转换器等高频应用的效率;
  3. 易驱动设计:1V低阈值兼容多种低压驱动电路,无需额外升压,简化系统设计;
  4. 宽温可靠性:-55℃~+150℃覆盖绝大多数应用场景,包括工业级环境与高温便携设备;
  5. 小体积集成:SOT-23封装便于在小型化产品(如蓝牙耳机、智能手环)中集成。

五、典型应用领域

  1. 便携电子设备:智能手机、蓝牙耳机、智能手表的电源开关、负载管理电路,利用小封装与低功耗提升续航;
  2. 小功率DC-DC转换器:作为同步整流管或开关管,应用于5V转3.3V、12V转5V等低压电源系统;
  3. 电池保护电路:锂离子电池过充/过放保护,低导通电阻减少电池能量损耗;
  4. 小型电机驱动:玩具电机、小型风扇的驱动电路,支持5.6A连续电流满足负载需求;
  5. 工业控制模块:工业传感器节点、小型控制单元的电源管理,宽温特性提升可靠性。

WST3400S凭借低功耗、小体积、宽温可靠性等优势,成为低压小功率场景的理想MOSFET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
