Relay Diode Schematic. This is particularly important when the relay circuit shown below is triggered with a transistor imagine a transistor replacing switch next to the battery. It is in the reverse biased position when the relay is turned on.
Note that the placement of the diode does not prevent a voltage spike from travelling to some downstream load. In this schematic the resistor r in parallel with the flyback diode wiring represents the coil s intrinsic dc resistance. Flyback diode wiring in a relay circuit.
