Product details

Gate charge and switching speed

The NP109N04PUK-E1-AY: Total gate charge is 189 nC at 10 V gate drive. The input capacitance is 10800 pF at 25 V drain-source.

Thermal headroom and package

The TO-263 (D²Pak) surface-mount package exposes a large copper tab on the bottom for heatsinking. With proper PCB copper area and thermal vias, the device can dissipate up to 250 W at the case — but the 1.8 W at ambient rating reflects the bare-board limit without a heatsink.

Lifecycle and compliance

For new designs, the active lifecycle means no supply discontinuity risk from obsolescence.

Frequently asked questions

Is NP109N04PUK--AY RoHS compliant?

Yes, the NP109N04PUK--AY is ROHS3 compliant.

What is the closest functional second-source for NP109N04PUK--AY?

The NP179N055TUK--AY is a higher-voltage (55 V), higher-current (180 A) N-channel MOSFET in the same TO-263 package with a similar 1.75 mOhm Rds(on) at 10 V gate drive. It also carries an AEC-Q101 automotive qualification. While not a direct pin-for-pin replacement due to different voltage and current ratings, it shares the same package and gate-drive voltage, making it a candidate for designs that need more headroom.
