MMDT3904-TP 是 MCC(美微科)提供的一款双通道 NPN 双极性晶体管阵列,采用紧凑的表面贴装封装 SOT-363(6 引脚)。每通道为标准小信号 NPN 晶体管,具有 40V 的集电极-基极耐压、最高 200mA 的集电极电流能力和 300MHz 的特征频率,适合中频放大与通用开关应用,特别适用于高密度 PCB 设计与便携式电子设备。
MMDT3904-TP 使用 SOT-363 封装(微小型 6 引脚),利于自动化贴装与回流焊工艺。由于单通道额定功耗 Pd = 200mW,设计时应考虑封装的热阻和板上散热路径:
MMDT3904-TP 由 MCC(美微科)供应,可在常用电子元器件分销渠道采购。为获得完整的电气特性曲线、引脚定义、热阻与典型应用电路,建议下载并参考 MCC 官方数据手册,或联系技术支持获取封装图与推荐的 PCB 布局示意。
如需基于本器件的电路方案(偏置、电平转换或射频前端设计)示例,可提供具体应用场景与工作条件,我将协助给出可行的电路建议与参数计算。

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.
