6. Frequently Asked Questions
▶>
It is IR’s proprietary MOSFET structure offering very low RDS(on), high current capacity, and fast switching — ideal for power converters and switching supplies.
>
It is widely used in automotive designs, though not AEC-Q100 certified unless specifically marked.
>
Yes, IRL3705 and IPP075N15N3 offer surface-mount options, but require thermal considerations.
>
Due to its relatively high gate charge (170nC), a strong gate driver IC is recommended for efficient switching.
>
IRFB7537PBF handles significantly higher current and lower RDS(on), making it more efficient and robust in high-load applications.
