VB2290 是 VBsemi(微碧半导体)推出的一款小封装 P 沟道场效应晶体管(P-MOSFET),采用常见的 SOT-23(TO-236)封装,面向便携电源管理和低电压大电流开关场合。器件在低驱动电压下具有较低的导通电阻与适中的开关电容,适合用作高端(高侧)开关、功率路径切换和反向极性保护等场景。
这些参数使 VB2290 在 2.5 V 至 4.5 V 的逻辑电平驱动下,既能实现快速切换,又能维持较低的导通损耗。
SOT-23 封装体积小,热阻较大,器件标称 Pd=1.6 W 是在良好 PCB 散热条件下的参考值。实际应用中建议:
VB2290 在 SOT-23 小封装中提供了适用于低压高侧开关的良好性能组合:低导通阻抗、逻辑电平驱动兼容和适度的开关特性。对空间受限且要求简单电源管理的电子系统,是一个实用且易于实现的 P 沟道 MOSFET 解决方案。根据实际工作电流与散热条件,合理布线与散热设计能够充分发挥其性能。

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.
