Hi All, So I have two large (25A @ 12v) fans that I am controlling via PWM and some MOSFETS. They are working but I am seeing 62v PTP with the scope at the Fets output. I have a schottky diode across the fan terminals at the fans, but am still getting the 62v spike briefly. Better way?

Clamping inductive kickback of PWM fans?

briefly.

(can you elaborate on that since you have a scope ? What is your idea of "briefly" ?
?
