I'm picking a MOSFET for a PWM motor control circuit and happened to stumble across several high-amp kits that are available for sale on the net that are using IRF7862PBF and IRF8734PBF. They seem to be very similar in characteristics and capable of handling up to 17A continuous current so I was going to order them for my project but then I noticed that they seem to have a very high Rds. Am I reading this wrong or is it true that they have around 3Mohm ON resistance? Why would you want Rds this high? I thought you want Rds as low as possible for switching circuits.
Thank you!
Thank you!
