Infineon
A strong match with identical key parameters, likely differing only in tape and reel packaging.
Find substitutes for the Infineon IRF540NSTRLPBF, a 100V, 33A N-Channel MOSFET in a D2Pak package. This page analyzes potential replacements, highlighting key parametric differences to ensure design compatibility.
Many alternatives have different gate charge (Qg), impacting switching.
Most candidates share the same D2Pak package.
Direct replacement for IRF540NSTRLPBF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
IRF540NSTRRPBF is a direct packaging variant. For performance upgrades, consider candidates with lower Rds(on) but verify gate charge (Qg).
The main risk with other alternatives is a mismatch in gate charge (Qg), which affects switching speed and driver circuit requirements.
