Hi guys I have a drill brand name 'casals' that stopped working. When I opened it found a type of diode with switch that was burned. Would like to know what this diode was so I can change it.
Thanks.
In my experience... Burnt components are usually down to excess current flowing through them Once you change the diode check the motors current draw...
That most likely is a Universal (brushed) motor, I have never seen a diode on any of these before, be interesting to know the function of the diode in this case, are you sure it is in fact a diode?
Max.

Don't know exactly if is a diode cause it's broken in two but looks like a diode.
The thing I don't know what type cause with burnt no codes are visible
Perhaps the 'diode' is indeed a diode, either bypassed or providing half-wave rectification for a universal motor according to the speed selector position.

Sounds to me like a rectifier diode that's used to halve the voltage for low speed. If it now runs only on high speed, then it's failed short.
I would replace it with the highest current diode that you can make fit in the space.
If your mains voltage is 120, use at least a 200 volt diode. If 240, use at least a 400 volt one. But I would probably choose a 800 or 1000V part as it's not going to be much more money and will be more immune to the transients coming off the motor brushes.
