If you only download 10 datasheets, make it these. These parts are the "Rosetta Stone" of the MOSFET world. If you memorize these, you have a portable equivalent book in your head.
How much current the part can handle.
Creating a custom spreadsheet is the only way to have a reliable 'book' for your specific applications. all mosfet equivalent book datasheet
For SMD parts (like "K72" or "1P"), the part number is not printed. You need an SMD codebook. If you only download 10 datasheets, make it these
Even with a perfect datasheet, beginners make three fatal errors: If you only download 10 datasheets
: A massive repository where you can search for "All MOSFET Equivalent Book" to find scanned versions of historical data books and current technical datasheets. Haseeb Electronics
