Hi JF

Again thanks for the info.

I went shopping the other day and they didn't have the parts I was
looking for. So now I'm searching online to try and find them on some
online shops.

I found a pretty good webites to get datasheets. But I have to open
every one to see if it qualifies.

Do you know:
1. It seems like there's an international product numbering system for
electronic components (or does every manufacturer number their own
way?)
2. Is there a place where I can search all MOSFETS (e.g.) and find the
code for the ones that qualify for me. E.g. 5V gate and 200V for the
supply.

Regards & Merry Christmas
