WSP4407的性能特点使其适配多个功率转换场景,典型应用包括:
相比同类P沟道MOSFET,WSP4407具备以下突出优势:
12mΩ@10V的导通电阻是同类产品中的优势指标,导通时功率损耗(P=I²R)显著降低,尤其在大电流场景下(如10A持续电流),损耗仅1.2W左右,远低于高阻产品,有效提升系统能效。
连续13A漏极电流支持大多数低电压大电流应用(如12V系统下的10A输出),无需并联器件即可满足需求,简化电路设计,降低成本。
-55℃~+150℃的工作温度覆盖工业级标准,可适应低温环境(如户外设备)与高温环境(如电源模块内部),器件稳定性与寿命得到保障。
[email protected]的栅极电荷与合理的电容参数(Crss=345pF),既保证了开关速度(适合高频应用),又降低了电磁干扰(EMI),减少额外滤波电路设计。
为充分发挥WSP4407的性能,电路设计需注意:

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
