IRFR3504ZTRPBF is a D-PAK N-MOSFET candidate but has lower voltage rating.
IRLR024NTRPBF is a 55 V D-PAK N-channel MOSFET. Current candidates require FAE review before use.
40 V candidate is below 55 V target
D-PAK matches, pinout not checked
Discrete MOSFET
Lifecycle fields are limited
Direct replacement for IRLR024NTRPBF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a 55 V or higher N-channel D-PAK MOSFET with verified pinout.
Lower VDS or unverified pinout can cause field failure.
