SI2308DS-T1-GE3-VB是VBsemi(微碧半导体) 推出的N沟道增强型MOSFET,核心优势为「小封装、低导通损耗、宽温适配」,主打低压小功率场景的开关控制与电源管理。采用SOT-23-3贴片封装(尺寸约2.9×2.5×1.3mm),适合高密度PCB设计;参数覆盖60V耐压、4A连续漏极电流,可覆盖多数便携电子、小型电源及工业控制小模块的需求。
导通电阻是衡量MOSFET损耗的关键指标,该器件表现突出:
实际损耗计算:以4A连续电流为例,Vgs=10V时损耗仅1.2W(I²×R=4²×0.075),发热可控,无需额外复杂散热。
结合参数特性,该器件主要适配以下场景:
采用SOT-23-3贴片封装,尺寸紧凑,适合高密度PCB布局;VBsemi作为国内成熟厂商,器件一致性与可靠性经过批量验证,可满足量产需求。
该器件凭借「小封装+低损耗+宽温」的综合优势,成为低压小功率场景的高性价比选择。

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.
