VBA1158N 是微碧半导体(VBsemi)推出的一款单通道 N 沟道 MOSFET,基于 Trench 制程工艺并采用 SOP-8 封装,面向小型电路板与中低功率开关应用。器件额定漏源耐压 150V,连续漏极电流 5.4A,适合要求中等耐压但受限于封装散热的小体积设计场景。
SOP‑8 封装便于小尺寸 PCB 布局,但散热能力受限。Pd 标称为 5.9 W,但实际可用功耗应按 PCB 铜箔面积、焊盘热阻和环境温度进行降额:
总结:VBA1158N 在 150 V 耐压与 SOP‑8 小封装之间提供了平衡,适合空间受限且需中等电压余量的电源与开关场景。关键是留意封装散热能力与栅极驱动设计,以确保在目标应用中的可靠性与效率。若需要更具体的热阻、结温曲线或完整参数表,请参考厂方详细数据手册。

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.
