As far as I know esp spi can be up to 3.3V and 40ma max with around a 50% duty cycle. 3.3 x .04 = 0.132 / 2 = 0.066W. I want to use 0201 1/20W .05W series termination resistors, but according to the math, they could get too hot.

I know I dont understand something about this because I see designs with 0201 on spi all the time. Can somebody please explain this to me, thank you.

I cant find any info on the standard esd diodes used. I would apreciate any suggestions and reasons why. Thanks guys.

8-SOIC

TO-220

if the 8-SOIC is the SO-8, where is the heatsink?

The TO-220 is a standard through hole with its heatsink off the pcb so would they bend it to make the heatsink touch the pcb or would a bolt in attachable heatsink need to be used in that situation?

My current process is...

1. Ask all AI's (chatgpt, Grok, Gemini). I provide 2-3 requirments or minimums that have to be met like 100V 50ma minimum for example.
2. I search on digikey with my minumium specs and sort by Most Popular.
3. I look for common parts suggested by the first 2 steps and I look through there datasheets.

Is there any way I could optimize my part finding process any furthur or is that just about what everyone does?

Max VCEO = 150V current = 200ma switching speed = 10-30khz Power 15W.

Im looking at these right now, I dont know if there are better ones I should look at or maybe ones that are more commonly used.

btw. I will be driving them with a mcu like a esp32

Output of convertver max = 150V 150ma

Diodes Ive found so far

ES3D 3A 200V ~20ns

MUR120 1A 200V 25ns

MUR420 4A 200V ~25ns

Output of convertver max = 150V 150ma

Diodes Ive found so far

ES3D 3A 200V ~20ns

MUR120 1A 200V 25ns

MUR420 4A 200V ~25ns

My switching will be around 2-3A and the output voltage will be 150V max, 100khz.

Im looking on digikey and I asked AI but I dont really know which ones are the good ones that are commonly used.
