SI2302DS-T1-GE3-VB 为 VBsemi(微碧半导体)推出的一款 SOT-23 封装 N 沟道功率 MOSFET,关键参数如下:Vdss = 20 V,连续漏极电流 Id = 6 A,导通电阻 RDS(on) = 22 mΩ @ Vgs = 4.5 V,耗散功率 Pd = 1.3 W,阈值电压 Vgs(th) = 1 V @ Id = 250 μA;栅极总电荷 Qg = 8.8 nC @ 4.5 V;输入电容 Ciss = 865 pF,输出电容 Coss = 105 pF,反向传输电容 Crss = 55 pF。工作结温范围 -55 ℃ ~ +150 ℃(Tj)。
总结:SI2302DS-T1-GE3-VB 在 20 V 档位提供了低 RDS(on) 与小封装的平衡,适合便携电源管理与低压开关场合,但在高功率或高频应用中需重视散热与驱动设计。

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.
