Requires 10 V gate drive for minimum on-resistance. The headline on-resistance is 1.75 mOhm maximum at 55 A drain current with 10 V gate drive — this is the number that sets conduction losses in a high-current path like a motor drive or DC-DC converter output stage. Gate charge totals 294 nC at 10 V, and input capacitance is 16050 pF at 25 V drain-source — these drive the switching speed and gate-driver sizing. ## Thermal reality: 348 W at case, 1.8 W at ambient The power dissipation spec tells the real story: 348 W maximum when the case temperature is held at 25 °C, but only 1.8 W when the ambient air is 25 °C. That 200× ratio means this MOSFET will not deliver 110 A without a heatsink — the D²Pak tab must be soldered to a large copper plane or bolted to a heatsink to keep the junction below the 175 °C maximum. The operating junction temperature is rated to 175 °C, which is typical for automotive-grade power MOSFETs and gives some headroom in a thermally marginal layout. ## TO-263 (D²Pak) — surface-mount power footprint The NP110N055PUK--AY comes in a TO-263-3 package, also called D²Pak (2 leads plus tab). This is a surface-mount package with an exposed drain tab that must be soldered to the PCB copper pour for both electrical connection and heat spreading. The tab is the drain terminal — the PCB land pattern needs a large copper area with thermal vias to inner layers to pull heat away from the junction. ## Peer comparison: NP179N055TUK-E1-AY It shares the same 55 V drain-source rating, same 1.75 mOhm Rds(on) at 10 V, and same 175 °C junction temperature, but it is rated for 180 A continuous drain — 70 A more than the NP110N055PUK--AY. Its gate charge is lower at 240 nC, which reduces driver losses at high frequency. The NP179N055TUK--AY also carries AEC-Q101 automotive qualification, making it the preferred choice for under-hood or chassis-domain applications where the NP110N055PUK--AY lacks that certification.","metaTitle":"NP110N055PUK-E1-AY N-Channel MOSFET, 55 V, 110 A, TO-263","metaDescription":"NP110N055PUK-E1-AY N-Channel MOSFET, 55 V drain-source, 110 A continuous drain, 1.75 mOhm Rds(on) at 10 V.
