30CTQ045 diode in motor driver

Hi everyone,

I’m designing a small motor driver / power supply circuit for robotics, and I’m considering using the 30CTQ045 diode as part of the output / protection stage. 
.

From what I saw:

It’s a fast switching diode rated for fairly high current and voltage (check the datasheet for exact specs).

It seems like a good candidate for clamping, reverse protection, or in the output stage of a driver.

Project Context

It’s for a robotic platform or small autonomous vehicle.

The motor driver stage works at 12 V (or potentially up to 24 V) with PWM switching at maybe 20–50 kHz.

I want to incorporate safety / protection: reverse voltage, back-EMF suppression, and prevent voltage spikes from damaging downstream electronics.

Questions 

Has anyone here used the 30CTQ045 diode or a similar fast diode in a motor driver or robotics power circuit? What was your experience with switching losses, heat, and reliability?

For motor driver protection / clamping, would you place this diode across the motor, in series with supply, or as a flyback / freewheel path?

In PWM / switching circuits, do you recommend adding RC snubbers, TVS diodes, or other suppression around diodes like this for better performance?

From layout/design perspective, how do you manage trace lengths, thermal paths, and whether to use heat sinks or copper pours to help dissipate heat from the diode?

Thanks to anyone who takes time to share your experiences or suggestions. I want to make sure the protection / power stage is robust before I commit to board fabrication.
