To prevent this, a flyback diode is typically placed in parallel with the relay coil. The diode allows normal current to flow through the coil when the relay is energized, but when the relay is turned off, the diode provides a low-resistance path for the stored energy to dissipate, preventing the high voltage spike from damaging the circuit.
