20N04-MS 是 MSKSEMI(美森科)推出的一款 N 沟道功率 MOSFET,面向中低压、高电流但受封装热限制的场景设计。器件在 40V 漏源耐压下,具有较低的导通电阻和适中的栅极电荷,适合作为开关管或低压差导通器件使用。其工作温度范围宽(-55℃ 至 +150℃),适应工业级环境。
20N04-MS 采用 SOT-89 小型封装,优点是体积小、适合空间受限的板上应用;缺点是热阻较高,耗散功率仅 1.5W(典型),无法像大封装那样直接承载长时间的大电流。推荐做法:
总结:20N04-MS 在 40V/25mΩ(4.5V 驱动)规格下,是一款适用于空间受限、需要中等导通电阻的 N 沟 MOSFET。封装限制了长期大电流能力,良好的 PCB 散热设计和合适的驱动电压是发挥其性能的关键。请以厂家完整数据手册为最终设计依据。

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.
