WPM3407 是 TECH PUBLIC(台舟电子)推出的一款低压 P 沟道场效应晶体管(P‑MOSFET),采用 SOT‑23 小封装,适合用于便携式电源管理与低功耗系统的高侧开关与保护电路。器件在 30V 漏源电压范围内提供约 4.1A 的连续漏极电流能力,具备较低的导通电阻和适中的开关能耗,适合在空间受限且需高侧控制的应用中使用。
注:为 P 通道器件,标称的 VGS、Qg 等多以绝对值说明;在实际电路中需注意门极相对于源极的极性(将栅极拉低于源极以导通)。
总结:WPM3407 在 SOT‑23 小封装中提供了 30V 耐压、约 4.1A 电流能力与较低的导通电阻,适合用于空间受限的高侧开关与电源管理场合。设计时需注意栅极驱动电压、热耗散与切换损耗,通过合理的 PCB 布局与门极抑制措施可获得稳定可靠的实际表现。若需更详细的参数曲线或封装尺寸信息,建议参考厂商完整数据手册并进行样片验证。

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.
