Hi all,
In a car audio amplifier, there are four MOSFETs for the amplification, they are K1420. I just want to know if IRF540 is a good replacement or no.
comparing both mosfets datasheets, I found that IRF540 exceeds the k1420 in the main power, current and voltage characteristics, but rds(on) of IRF540 is about 0.07Ω while it is 0.04 for k1420. Also the rising and falling time (on & off) differs to about twice..
Any help?
Regards,
Hazim
