2SK3756 是东芝(TOSHIBA)生产的一款 N 通道射频功率 MOSFET,面向 470 MHz 频段的射频放大应用。器件在紧凑封装下提供较高的增益和输出功率,适用于便携式射频发射/驱动模块及中低功率无线通信终端的功率放大器(PA)或功率驱动级。
在厂家标注或典型应用中,2SK3756 在 Vds=4.5 V、Id≈200 mA 的偏置条件下可达到约 32 dBm 的输出功率,同时保持约 12 dB 的增益。这表明器件在中低电压供电、适中偏流条件下可实现高效率的射频输出,适合便携供电环境(如手持无线电、无线模块)或作为驱动级使用。实际性能会随匹配网络、负载、偏置点和散热条件变化,设计时须以完整数据手册和电路仿真为准。
2SK3756 采用 TO-243AA 外壳(供应商标识 SC-62),为紧凑型表面贴装封装。封装利于小型化电路板布局,但热阻相对较小器件需要关注:
总结:2SK3756(TE12L,F)是一款面向 470 MHz 频段的 N 通道射频功率 MOSFET,在 4.5 V/200 mA 的测试条件下可提供约 32 dBm 的输出功率和约 12 dB 的增益,适合中低功率无线发射和驱动应用,但设计时需重视偏置、匹配与散热管理以保证性能与可靠性。

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.
