90 A, 60 V N-Channel — what it handles
The NP90N06VDK-E1-AY: That current rating puts it in the high-current tier for a TO-252 package — the tab carries the bulk of the thermal path, so the 147 W maximum dissipation at the case is the real limit.
The threshold voltage is 2.5 V max at 250 µA.
AEC-Q101 and the 175°C junction limit
This part is qualified to AEC-Q101. The maximum operating junction temperature is 175°C.
Package and rework — TO-252 reality
The NP90N06VDK--AY comes in a TO-252-3 (DPak) surface-mount package with two leads plus the tab.
