WsD3056DN33 产品概述

一、产品简介

WsD3056DN33 是 WINSOK(微硕)推出的一款高性能沟槽式双 N 沟道 MOSFET,封装为 DFN-8 (3×3)。器件集成两颗 N 沟道场效应晶体管,针对同步降压转换器及各类开关电源、负载开关和功率分配场景做了性能与密度优化。产品符合 RoHS 要求,100% 通过功能可靠性认证,适合要求紧凑布局与高效率的电源设计。

二、主要参数与性能亮点

  • 电压与电流:Vdss = 30V,连续漏极电流 Id = 35A(具体允许值需按封装散热条件与环境温度作热度降额)。
  • 导通电阻:RDS(on) = 13 mΩ @ Vgs = 10V,适合低导通损耗应用,提升转换效率。
  • 开关特性:总栅极电荷 Qg = 7.2 nC @ 10V,Ciss = 620 pF,Coss = 85 pF,Crss = 30 pF,综合表现利于中高速开关(降低开关损耗与驱动负担)。
  • 阈值电压及功耗:Vgs(th) = 2.5V,最大耗散功率 Pd = 27W(在规定的散热条件下)。
  • 工作温度范围:-55 ℃ 至 +150 ℃,适配工业级环境。

这些参数表明 WsD3056DN33 在 30V 级别功率开关中具备良好的导通/开关折中,适合同步整流场合与高密度电源模块。

三、封装与可靠性

采用 DFN-8 (3×3) 小型封装,适用于高度集成的 PCB 布局。DFN 封装有利于降低寄生电感、缩短电流回路,但对 PCB 散热设计与焊盘布局要求较高。产品已通过功能可靠性测试并符合 RoHS,适合量产使用。实际热性能(如 θJA/θJC)与可靠额定需参考完整数据表并结合 PCB 铜箔面积与过孔设计评估。

四、典型应用

  • 同步降压转换器(高侧/低侧功率开关)
  • 电源管理与负载开关
  • 电池供电系统与便携设备的电源路径控制
  • 高密度服务器、通信设备的点对点供电模块

五、设计与使用建议

  • 栅极驱动:为实现标称 RDS(on),建议 Vgs 取 10V;若采用逻辑电平驱动(如 5V),请在原厂数据手册中确认对应 RDS(on) 与开关损耗。
  • 布局与散热:尽量缩短开关回路(电感—MOSFET—电容)走线,增大 PCB 铜箔与过孔用于散热,必要时在底部焊盘处采用热导垫或多层散热过孔。
  • 开关控制:基于 Qg 与寄生电容特性,选择合适的驱动器并在需要时串联小电阻以抑制振铃与限流冲击。
  • 可靠性裕度:按照应用环境对 Id、Pd 做热降额,避免长时间在最高额定条件下工作。并在布局中预留必要的测试与保护措施(过流、过温、ESD 防护)。
  • 并联与匹配:若需更低 RDS(on) 或更高电流,可考虑并联多颗 MOSFET,同时注意栅极走线匹配与电流均流问题。

结语:WsD3056DN33 针对 30V 级别的同步整流与功率开关应用提供了低导通阻抗与适中开关电荷的平衡方案,适合对体积与效率有要求的电源设计。选型时请参考完整数据手册以获得温度依赖、包络图及具体测试条件下的参数。

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
