WPM3028-8/TR 产品概述

一、概览

WPM3028-8/TR 是 WILLSEMI(韦尔)推出的一款高性能 P 沟道场效应晶体管,封装为 DFN-8L (3×3)。器件设计面向中低电压、高电流功率开关场合,具有极低的导通电阻和较大的输入/输出电容,用于高效能量传输与开关控制。器件额定工作温度范围宽 (-55℃ ~ +150℃),适合工业和汽车级环境。

二、主要电气参数

  • 型号:WPM3028-8/TR,P沟道 MOSFET(数量:1)
  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:22 A
  • 导通电阻 RDS(on):11 mΩ @ 10 V(按规格书测试条件)
  • 阈值电压 Vgs(th):1 V(典型/测试条件需参考数据表)
  • 总栅极电荷 Qg:38 nC @ 10 V
  • 输入电容 Ciss:2.106 nF @ 15 V
  • 输出电容 Coss:353 pF
  • 反向传输电容 Crss:274 pF @ 15 V
  • 功耗 Pd:43 W

三、性能要点与优势

  • 极低的 RDS(on)(11 mΩ)在大电流场合可显著降低导通损耗,提高转换效率。
  • 较高的 Id(22 A)和较大 Pd(43 W)允许在紧凑封装中处理较大的连续功率。
  • 较大的 Ciss 与 Qg 表明开关时需要考虑足够的驱动能力与栅极驱动能量管理;Coss/Crss 数据利于估算开关损耗与电压应力。
  • 宽温度范围(-55℃~+150℃)增强了在严苛环境下的可靠性。

四、典型应用场景

  • 高侧(P沟道)功率开关与负载断开(电源路径切换、背靠背保护)
  • 电池管理与电源选择(便于在正端进行简单的高侧控制)
  • 便携设备与工业设备中的低压 DC-DC 转换器(用作高侧开关或保护元件)
  • 逆流/反接保护、热插拔电源管理

五、布局与使用建议

  • 由于器件为 DFN-8L (3×3),请在 PCB 布局中为底部热焊盘设计充足的铜箔与过孔(热通道)以提升散热能力,保证 Pd 条件下的稳定性。
  • 栅极驱动:规格给出的 RDS(on) 与 Qg 均基于 10 V 驱动条件(注:P 沟道器件在高侧应用时需提供相应极性驱动以获得规定的 Vgs),驱动器需能提供足够的电荷并控制开关速度以兼顾开关损耗与电磁干扰。
  • 在高速开关应用中,Crss 带来的米勒效应需在驱动设计与缓冲网络中加以抑制,建议并联合适的栅极电阻与驱动缓冲。
  • 系统设计中应留意 Vdss=30 V 的限制,避免瞬态过电压造成击穿。

六、选型与可靠性考量

选择 WPM3028-8/TR 时,应结合系统电压余量、最大导通电流与散热条件评估实际工作点;在高频切换场合,需综合考虑 Qg、Coss/Crss 带来的动态损耗与驱动器需求。对于汽车或工业级应用,建议参考制造商完整数据手册以获取绝对最大额定、热阻与典型特性曲线,进行仿真验证与热设计。

总结:WPM3028-8/TR 在 DFN-8L 小封装中提供了低导通电阻与较高电流处理能力,适合需要紧凑布局且对开关效率与温度耐受有较高要求的高侧功率管理场合。

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
