Please correct me if I'm wrong as this is the approach I'm taking with my build.  |
I've seen reasonable diodes in that package, but not good MOSFETs.
Avnet has a good price, $18.53, on the STPS200170TV1 diode in an ISOTOP package. That's 200A at 170V, which should be good for up to 150V traction voltage (the diode sees lower peak voltages than the MOSFET).
