I'm designing a circuit based on the LTC4091 typical application:
They use two Vishay SiS447DN P-Channel 20V MOSFETs. Unfortunately those parts are not in stock neither at Mouser nor DigiKey, so I'm looking into replacement parts. I'm not sure what to look for in a compatible MOSFET, besides the Vds = 20V.
I found this dual MOSFET chip : NVMD6P02 which shares some characteristics but Rds(ON), Id and Qd are off by at least an order of 10, so I'm not really sure it could be a good replacement.
If not, what would be a good replacement part, or more generally, what parameter to look for in an equivalent MOSFET ?
Edit : I'm currently designing the PCB so the package is not important as I can change it as long as I find a readily available equivalent part.
