WSP4807 P沟道MOSFET产品概述

一、产品基本属性与定位

WSP4807是WINSOK(微硕) 推出的一款双P沟道增强型MOSFET,采用SOP-8小型贴片封装,专为低压小功率场景下的开关控制、负载切换等需求设计。该器件整合2个独立P沟道MOSFET于紧凑封装内,既节省PCB空间,又简化电路设计,适用于消费电子、移动设备、小型家电等领域的低压应用。

二、核心电气参数解析

WSP4807的关键参数针对低压场景优化,核心表现清晰:

  1. 耐压与电流能力:漏源击穿电压(Vdss)达30V,覆盖12V、24V等常用低压直流系统;连续漏极电流(Id)为8.9A,满足多数小功率负载的持续工作需求。
  2. 导通损耗控制:在栅极电压Vgs=-4.5V(P沟道为负电压驱动)、漏极电流Id=5.6A条件下,导通电阻(RDS(on))仅32mΩ,低导通损耗可有效减少功率浪费,提升系统效率。
  3. 开关特性:栅极总电荷量(Qg)为20nC(Vgs=-10V时),输入电容(Ciss)1.004nF、反向传输电容(Crss)154pF,开关速度适中,兼顾开关损耗与导通损耗的平衡,适合100kHz以下的中等频率应用。
  4. 阈值与功耗:栅源阈值电压(Vgs(th))为-2.3V(漏极电流Id=250uA时),可被3.3V/5V MCU直接驱动,无需额外驱动电路;最大耗散功率(Pd)2.5W,小功率场景下无需复杂散热设计。

三、典型应用场景

WSP4807的参数特性使其适配多种低压应用:

  1. 低压电源开关:12V/24V直流电源的通断控制,双P沟道可实现双向开关或多路独立控制。
  2. 移动电子设备:移动电源、蓝牙音箱、便携式医疗设备的负载切换,低导通损耗延长电池续航。
  3. 电池保护电路:电池负极侧(低边)的过流/过放保护,P沟道特性适配电池驱动场景。
  4. 小型家电控制:加湿器、台灯、智能插座的开关控制,2.5W功耗满足小功率负载需求。
  5. LED驱动辅助:低压LED串的开关或调光控制,稳定的开关特性保障LED亮度均匀。

四、产品优势与设计提示

核心优势

  • 集成化设计:SOP-8封装内置2个P沟道MOSFET,减少元件数量与PCB面积,降低BOM成本。
  • 低压驱动友好:4.5V栅极电压下低导通电阻,可直接由MCU驱动,简化电路结构。
  • 效率与可靠性平衡:导通损耗低+开关损耗适中,兼顾系统效率与长期可靠性。

设计注意事项

  • 栅极防护:MOSFET易受静电损坏,组装/测试需采用ESD防护措施;栅极电压绝对值不超过20V(参考同类产品通用额定值),避免过压击穿。
  • 散热考量:若连续工作在8A左右大电流下,需适当增加PCB铜箔面积(建议≥10cm²),或搭配小型散热片。
  • 双管应用:两个P沟道为独立器件,可分别用于不同通道,也可并联提升电流能力(并联需确保参数匹配)。

五、总结

WSP4807作为一款高集成度的双P沟道MOSFET,以30V耐压、8.9A电流、低导通电阻为核心优势,适配低压小功率场景的开关控制需求。其紧凑的SOP-8封装、MCU直接驱动能力,使其在消费电子、移动设备等领域具有较高的性价比,是低压应用中简化电路、提升效率的理想选择。

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
