AOD442 是友台半导体(UMW)推出的一款60V额定电压的N沟增强型功率MOSFET,采用TO-252(DPAK)封装。凭借低导通电阻与较高的额定电流,适用于开关电源、同步整流、降压转换及功率管理等中功率场景。其关键电气参数包括:Vdss = 60V、连续漏极电流 Id = 37A、RDS(on) = 16mΩ@Vgs=10V(20mΩ@Vgs=4.5V),栅极电荷 Qg = 47.6nC(10V),输入电容 Ciss = 1.92nF,反向传输电容 Crss = 116pF,输出电容 Coss = 155pF,工作温度范围 -55℃ ~ +175℃,耗散功率 Pd = 60W。
TO-252(DPAK)为表面贴装封装,热阻相对较小,但在高电流或高占空比工作时仍需依靠PCB散热。推荐:
AOD442 在60V额定、低RDS(on)与中等Qg的配置上具有均衡的性能,适合中功率开关与同步整流等应用。设计时要重点关注栅极驱动能力、PCB散热与寄生参数抑制,才能在保持高效率的同时保证可靠性。若需替代或并联使用,请核对热阻、二次特性及并联分流一致性,确保系统稳定运行。若需要详细的绝对最大额定值、完整特性曲线与封装图,请参考厂方数据手册或联系供应商获取原始资料。

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.
