When these inductive loads are tive load. The DC blocking voltage (VR) of the free-wheeling diode switched off, a counter emf can severely damage switch contacts can be found in the datasheet of a diode. The forward current and greatly shorten lifetime. should be equal or greater than the maximum current flowing through the load. Fig. 1 shows an inductive load with a free-wheeling diode con- nected in parallel. This free-wheeling diode provides a path for the To get an efficient protection, the free-wheeling diode must inductor current to flow when the current is interrupted by the be connected as close as possible to the inductive load! switch. Without this free-wheeling diode, the voltage across the coil will be limited only by dielectric breakdown voltages of the circuit or parasitic elements of the coil. This voltage can be kilo- volts in amplitude even when nominal circuit voltages are low (e. g. 12 VDC) see Fig. 2.
