Product details

The IRF9540NSTRLPBF: The maximum Rds(on) is 117 mOhm at 14 A and 10 V Vgs. The total gate charge is 110 nC at 10 V.

Package and thermal path — D2PAK mounting

The maximum power dissipation is 3.1 W at 25°C ambient and 110 W at 25°C case — the difference reflects the thermal resistance of the board. For high-current designs, a 2 oz copper pour under the tab is typical.

Temperature grade and application envelope

The 100 V Vdss and 23 A Id rating suit it for 48 V bus converters, battery-protection circuits, and high-side load switches in power-train and motor-drive applications.

Frequently asked questions

Can IRF9540NSTRLPBF replace IRF9540N in a circuit?

The IRF9540NSTRLPBF is a surface-mount D2PAK variant of the IRF9540N series. The base product number is IRF9540. The electrical specifications — 100 V Vdss, 23 A Id, 117 mOhm Rds(on) — are consistent with the IRF9540N family. The main difference is the package: D2PAK vs through-hole. If the board layout accommodates the D2PAK footprint and the thermal path, it is a direct functional replacement.
