Product details

The NP89N055PUK-E1-AY: The NP89N055PUK--AY: The NP89N055PUK--AY is a 55 V, 90 A N-channel MOSFET in the TO-263-3 (D²Pak) surface-mount package. Gate charge totals 102 nC at 10 V, which sets the drive current needed for the target switching frequency — a 100 kHz hard-switched converter draws about 10 mA from the gate driver.

Thermal budget and package reality

Power dissipation is rated 1.8 W at ambient (Ta) and 147 W at case temperature (Tc). Input capacitance is 6000 pF at 25 V drain-source — this dominates the switching loss at higher frequencies. The 4 V gate threshold at 250 µA is typical for logic-level drive, but the 10 V drive voltage for minimum Rds(on) means a 10 V rail or a bootstrap supply is needed to hit the 4 mOhm figure.

Sourcing posture and lifecycle

ROHS3 compliant.
