WSP4016 是 WINSOK(微硕)推出的一款 N 沟道功率 MOSFET,采用 SOP-8 封装,面向中低压开关和功率管理应用。器件在 40V 漏源耐压下能够提供较低的导通电阻与可观的连续电流容量,适合开关稳压、负载开关和电源保护等场景。
WSP4016 在 10V 栅压下表现出低至 8.5mΩ 的导通电阻,适合以 10~12V 驱动的功率级。Qg=20nC 与 Crss=70pF 表明该器件在开关时需要中等量级的驱动能量,开关速度与驱动强度、布局寄生电感相关。较低的 Coss 有利于降低换向能量。
SOP-8 封装的最大器件耗散 Pd=2.08W(典型条件),实际允许的持续电流受 PCB 散热能力限制。使用时应通过充分的铜箔面积、散热过孔和短电流回路来提高热扩散效率,必要时分摊功率或选用并联方案以降低结温。
推荐使用能提供稳定 10V 门极驱动的驱动器以实现标称 RDS(on)。阈值电压约 1V 表明在低电平驱动下器件可导通,但导通电阻会显著上升,建议避免在仅 3.3V 驱动下作为主功率开关使用,或在低压系统中评估温升与效率。
选型时应综合考虑 Vdss、RDS(on)、Qg、封装散热能力与目标工作点(频率、占空比、环境温度)。若系统驱动为 3.3V 或需更高持续功率,建议评估是否选用逻辑电平型 MOSFET 或更大封装以满足热性能需求。
WSP4016 以其 40V 耐压、低导通电阻与中等开关能量在中低压功率转换与开关应用中具有较高性价比;合理的驱动与散热设计可确保稳定可靠的长期运行。

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.
