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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
