30N03A 是 UMW(友台半导体)推出的一款高性能 N 沟道功率 MOSFET,封装为 TO-252(DPAK),面向需要大电流、低导通损耗和紧凑封装的功率电子应用。器件额定耐压 30V,连续漏极电流最高可达 90A,典型导通电阻在不同栅压下表现优秀,适用于同步整流、DC-DC 转换、负载开关与电机驱动等场景。
30N03A 为单个 N 沟道 MOSFET,工作温度范围宽(-55℃ 至 +150℃),承受严格的工业环境。器件在 10V 栅压下的导通电阻非常低(RDS(on) = 3.9mΩ),在较低的栅压 4.5V 下仍保持良好导通(RDS(on) = 6.5mΩ),这使其在既有 12V/24V 系统和部分 5V 驱动场合均有良好适配性。
TO-252(DPAK)封装适合表面贴装工艺,便于自动化装配。尽管封装紧凑,器件最大耗散功率达到 105W(在良好散热条件下),设计时应重点考虑 PCB 散热与热阻:
总结:30N03A 在 30V、90A 级别中以低 RDS(on) 与良好的封装适配性突显出其在高电流、紧凑功率设计中的竞争力。合理的栅极驱动、热管理与 PCB 布局能发挥其最佳性能。

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.
