I would love to see something on digikey or mouser that allowed me to search for MOSFETs in a way that was less painful.
Let's say you wanted to do a special purpose switching power supply. Digikey doesn't have a column for gate capacitance (for the mosfet), or Q (for the inductor). All that manual work to read datasheets is terrible, especially if your design takes a little while to perfect and some of the components go end-of-life, so you have to replace them.
I personally like to graph the cost-efficiency curve so I actually have to tabulate lots of mosfets, inductors, and caps, then simulate them in a spreadsheet.
I know about the specialized design tools done by each manufacturer that will recommend parts and do a design for you based on your criteria. I want something that does a much broader search for parts though.
Maybe I should write one. :)
- PeanutNore 10y agoMouser does have a column for gate charge that you can sort by.
- TD-Linux 10y agoDigikey does have the gate capacitance, just specified in a weird way - gate charge @ voltage. Most higher power FETs are always specified @ 10V gate, so it's directly equivalent.
- sounds 10y agoThanks! I wasn't able to figure out if it really was directly equivalent. (Thanks also to sibling comment pointing out Mouser has the same.)
- nitrogen 10y agoIs the Octopart search engine still running? Or something like it?
