Infineon ISC028N04NM5ATMA1 属于英飞凌 OPTIMOS 系列 40V N 沟 MOSFET,封装为 TDSON-8FL。该器件针对中高电流开关应用优化,典型参数包括:Vdss = 40V,导通电阻 RDS(on) = 2.8 mΩ @ VGS=10V (I=50A),栅极电荷 Qg = 38 nC @10V,输入电容 Ciss = 2.7 nF,输出电容 Coss = 750 pF,反向传输电容 Crss = 130 pF。阈值电压 Vgs(th)=3.4V,工作结温可达 +175°C(Tj)。
适用于汽车或工业的 12V/24V 到点对点 DC-DC 转换、同步整流、降压转换器、功率分配开关、马达驱动及负载开关等需要 40V 耐压与低导通电阻的场合。
若系统可提供稳定 10V 栅压并需在 40V 级别实现高效率与大电流,ISC028N04NM5ATMA1 是良好选择。对于 5V 直驱或极高开关频率场合,应评估在更低 Vgs 下的 RDS(on) 及驱动损耗,或考虑更低 Qg 的版本。最终选型请以完整数据手册与实际 PCB 热模型验证为准。
总结:该器件在 40V 类别中以超低 RDS(on) 和较高电流承载为优势,适用于需兼顾导通损耗与开关性能的电源与驱动设计。

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.
