The NP100P04PDG-E1-AY: The NP100P04PDG--AY is a P-Channel MOSFET rated for 40 V Vdss and 100 A continuous drain, housed in a TO-263-3 D²Pak surface-mount package.
Thermal limits and derating
Maximum power dissipation is 1.8 W at ambient (Ta) and 200 W at case temperature (Tc). The 100 A continuous rating applies at 25 °C case temperature — derate linearly above that per the datasheet curve.
Gate drive threshold and logic-level compatibility
Maximum threshold voltage is 2.5 V at 1 mA drain current.
