Introduction
IRF540NSTRLPBF Power MOSFET
The IRF540NSTRLPBF is an Infineon HEXFET® single N‑channel power MOSFET in a surface‑mount TO‑263 (D2PAK) package designed for high-power applications.
Key Features
- N‑channel enhancement mode technology
- VDS = 100 V with continuous ID = 33 A
- Ultra‑low RDS(on) = 0.044 Ω for minimized conduction loss
- Fast switching capability with low gate charge QG = 47.3 nC
- 100% avalanche‑tested for high energy-handling capability
- Dynamic dV/dt rating providing robustness against voltage transients
- Operating temperature: −55°C to +175°C
- RoHS‑compliant, lead‑free construction
- Surface‑mount TO‑263 (D2PAK) package for high-density PCB design
Core Function
As a voltage‑controlled power switch, the IRF540NSTRLPBF controls high‑power current flow between the drain (D) and source (S) by applying a small voltage to the gate (G).
OFF state: VGS < VGS(th) (max 4 V) creates high impedance between D-S, blocking current flow.
ON state: VGS > VGS(th) enables low RDS(on), conducting up to 33 A continuously.
Operates in switching mode (saturation/cutoff) for minimal power loss, or in linear mode for current regulation within safe operating area.
ON state: VGS > VGS(th) enables low RDS(on), conducting up to 33 A continuously.
