I have lost count of how many of those I have blown up! I used two 100A SSRs to switch a short Mag motor (no PWM) and they regularly died if the motor came close to stalling. Internally, they have two FETs in TO-220 cases. The other problem with these SSRs is impact resistance; mine had a thin a brittle plastic shell that quickly shattered. I had to cut the top of the shell off and inject potting epoxy to make them rugged enough for combat use.

On the other hand, they are super easy to control and the screw-on terminals make wiring easy too.
