WSE9968A N沟道MOSFET产品概述

WSE9968A是WINSOK(微硕)推出的N沟道增强型金属氧化物半导体场效应管(MOSFET),针对中低压中小功率应用场景优化设计,具备低导通电阻、高开关效率、宽温度适应性等特点,适用于便携式设备、电源管理、负载开关等多种场景。

一、产品基本定位

WSE9968A定位于中小功率高密度应用,采用SOT-89-3紧凑封装,单管N沟道结构,可满足100V以内电压范围、4A级连续电流的电路需求。其设计兼顾效率与成本,适合批量应用于消费电子、工业控制及车载周边等领域。

二、核心电性能参数解析

WSE9968A的关键参数围绕低功耗、易驱动、高可靠性优化,核心参数如下:

2.1 电压与电流能力

  • 漏源击穿电压(Vdss):100V,满足12V/24V/48V等中低压系统的耐压需求,预留足够安全裕量;
  • 连续漏极电流(Id):4.4A(25℃),可稳定承载中小功率负载的持续电流;
  • 脉冲漏极电流(隐含:通常脉冲电流会更高,适合短时过载场景)。

2.2 导通与开关特性

  • 导通电阻(RDS(on)):120mΩ(@Vgs=4.5V,Id=3.5A),低导通电阻直接降低导通损耗,减少散热需求;
  • 阈值电压(Vgs(th)):3V(@Id=250μA,25℃),与常见MCU/驱动IC的3.3V输出兼容,无需额外电平转换,驱动便捷;
  • 栅极电荷量(Qg):16nC(@Vgs=10V),低栅极电荷降低开关过程的能量损耗,提升开关效率,适合高频应用。

2.3 电容与温度特性

  • 输入电容(Ciss):980pF、反向传输电容(Crss):26pF、输出电容(Coss):46pF,电容参数匹配开关速度与EMI控制需求;
  • 耗散功率(Pd):3.5W(25℃),结合宽温度范围(-55℃~+150℃),可稳定工作于极端环境(如车载高温、工业低温场景)。

三、封装与可靠性设计

WSE9968A采用SOT-89-3封装(3引脚表面贴装),具有以下优势:

  1. 紧凑尺寸:封装体积小(典型尺寸约3.0×2.5×1.1mm),适合便携式设备、小型电源模块等高密度布局;
  2. 散热优化:引脚设计利于热量传导,配合3.5W耗散功率,可满足中小功率场景的散热需求;
  3. 可靠性保障:宽温度范围覆盖工业级与车载级应用,符合RoHS环保标准,长期工作稳定性高。

四、典型应用场景

WSE9968A的参数特性使其适用于以下场景:

  1. 电源管理模块:DC-DC降压/升压转换器(如12V→5V/3.3V)、线性电源辅助开关;
  2. 负载开关:便携式设备的电池供电开关、USB端口过流保护开关;
  3. LED驱动:中小功率LED串的恒流/恒压驱动(如台灯、小夜灯);
  4. 小型电机驱动:玩具电机、小型伺服电机、微型泵的驱动电路;
  5. 电池保护电路:锂离子电池组的充放电控制开关(配合保护IC)。

五、产品优势总结

WSE9968A相较于同类型产品,核心优势体现在:

  • 低导通损耗:4.5V栅极电压下120mΩ导通电阻,适合低电压驱动场景;
  • 易驱动性:3V阈值电压兼容3.3V系统,无需额外驱动电路;
  • 宽温适应性:-55℃~+150℃工作范围,覆盖工业与车载环境;
  • 高密度布局:SOT-89-3封装节省PCB空间,适合小型化设计;
  • 成本效益:平衡性能与成本,适合批量应用于消费电子及工业领域。

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
