I am checking out some diodes in a snubber circuit and would like to know if they are hefty enough. Does anyone know the calculations or rule of thumb for calculating what size a diode needs to be.
The schotsky diode are placed across the coil in a relay. The resistance of the coil is 1.3kOhms and the voltage is 24 volts. That means that the coil is drawing 18mA. The diodes are rated for 1 amp. I don't know the inductance of the coil.
Thanks
Bill
