Product details

40 V, 90 A N-Channel MOSFET for power rails and motor drives

The NP89N04PUK-E1-AY: This part targets low-voltage power conversion — synchronous rectification in 12 V and 24 V DC-DC stages, load switches, and motor-drive half-bridges where the 40 V ceiling provides margin for a 24 V bus. The 2.95 mOhm maximum on-resistance at 45 A with a 5 V gate drive means the part can be driven directly from a 5 V logic supply or a basic gate driver without a boost stage, keeping the BOM simple in low-voltage designs.

Without that thermal path, the 90 A rating is unreachable.

The TO-263-3 (D²Pak) with two leads plus a tab is a standard surface-mount power package.

Frequently asked questions

What is the maximum continuous drain current for NP89N04PUK--AY?

The continuous drain current is rated at 90 A at 25 °C case temperature. This rating requires adequate heatsinking — the TO-263 tab must be soldered to a low-thermal-resistance PCB copper area to achieve it.

Can NP89N04PUK--AY be used for high-frequency switching applications?

It is suited for switching frequencies up to about 100 kHz in hard-switched topologies. The 102 nC total gate charge and 5850 pF input capacitance are moderate — a gate driver with low output impedance (a few ohms) is needed to keep switching losses manageable at higher frequencies. For >200 kHz operation, a lower-Qg device would be more efficient.

Is NP89N04PUK--AY RoHS compliant?

Yes, it is ROHS3 compliant per the supplier's listing.
